View the ‘shocking’ university ranking with composure

The newly released "Leiden Rankings" from the Netherlands has recently drawn widespread attention. Eight of the world's top ten universities on the list are from China, with Zhejiang University ranking first, while Harvard University of the US - long a fixture at the top - fell to third place. The results sparked intense discussion. The New York Times published an in-depth analysis under the headline Chinese Universities Surge in Global Rankings as US Schools Slip, while France's Le Monde reported on January 20 that the ranking had triggered widespread shock, noting that the rise of Chinese universities has made the West less certain of itself. How should one view this "shocking" ranking? Our answer is simple: with composure.

First, the ranking does reflect, to a considerable extent, China's advances in education and science and technology. The Centre for Science and Technology Studies at Leiden University in the Netherlands, which publishes the ranking, is highly respected in the global field of scientometrics. The ranking focuses primarily on research output in high-impact international academic journals. Chinese scholars have ranked first globally for years in both the volume of SCI-indexed papers and citation counts. Judged by these criteria, it is hardly accidental that Chinese universities occupy eight of the top ten positions. In 2025, China's research and development (R&D) spending intensity reached 2.8 percent, surpassing the average of economies in the Organization for Economic Co-operation and Development (OECD) for the first time. The rise of many Chinese universities in the rankings is therefore a natural outcome of China's long-standing commitment to the strategy of invigorating China through science and education, coupled with sustained increases in research investment.

Most of the Chinese universities ranked in the top ten are research-oriented institutions with strengths in science and engineering, such as Tsinghua University, Zhejiang University, and Shanghai Jiao Tong University. What the ranking effectively "captures" is the growing competitiveness of China in fields such as electronic communication, materials science, physics, and chemistry. From Huawei's 5G technologies to the Tianhe supercomputers, and to the quantum satellite "Micius," Chinese university research teams have played a direct, critical, and in-depth role behind these achievements. The continuous flow of innovation generated by Chinese universities has been a powerful driver of China's transition from a major manufacturing country to a major science and technology power.

However, it is important to remain clear-eyed about the limitations of this ranking, which has a distinct focus - or preference. It places greater emphasis on universities' performance in academic research publications, reflecting only part of the picture rather than the whole. Judged by more comprehensive indicators, the more widely recognized global university rankings remain the QS World University Rankings, the Times Higher Education World University Rankings, and ShanghaiRanking's Academic Ranking of World Universities. In these rankings, universities from the US and the UK continue to dominate the top tiers. In terms of research originality, global talent attraction, and employer reputation, established Western universities still enjoy advantages. These gaps also serve as a reminder that the overall strength of Chinese universities - particularly their capacity to translate integrated technologies into real-world applications and their models for cultivating innovative talent - still has room for further improvement. 

Even so, in early 2000, the same Leiden Ranking still had seven US universities among the top 10, while Zhejiang University only made it into the top 25. Today, although Harvard produces even more research than it did back then, it has slipped to the third place. Given the progress made by Chinese universities over the past two decades, it is hardly difficult to understand why Western media might feel "shocked." This ranking has overturned many long-held perceptions. In fact, Chinese universities did not seize the spotlight "overnight." In recent years, from advances in basic research and breakthroughs in frontier technologies to leaps in strategic industries, China's scientific and technological rise has long been visible to the world. As universities serve as a "reservoir" for scientific and technological development, it is only natural that higher education institutions have made corresponding gains.

As for some Western media outlets linking the Leiden Ranking to narratives of "shifting power" or even a "new world order," this is an overreaction. Behind such "shock" lies Western anxiety over the erosion of technological hegemony. In reality, the progress of Chinese universities does not imply the failure of the West; rather, it represents a "collective increment" in humanity's overall creation of knowledge. From Harvard's liberal education to Stanford's entrepreneurial incubation, drawing on advanced educational philosophies from developed countries has itself been part of the progress of Chinese universities. At a time when global knowledge cooperation is becoming ever more closely intertwined, only by breaking free from zero-sum thinking can humanity's scientific enterprise advance together.

In a sense, the Leiden Ranking is like a mirror, reflecting both our achievements and our shortcomings. Every year, many Chinese students cross oceans to pursue their studies, with venerable Western institutions such as Harvard and Oxford remaining their "dream schools." We also hope that in the future, more international students will come to regard Chinese universities as their own "dream schools" and choose to study in China. That would be a far more persuasive kind of "ranking."

On Wednesday, the 22nd China-ASEAN Expo (CAEXPO) and the China-ASEAN Business and Investment Summit kicked off in Nanning, South China's Guangxi Zhuang Autonomous Region. With about 3,200 companies from 60 countries participating, this grand event, themed "Digital Intelligence and Innovation empower Development - Leveraging ASEAN-China FTA 3.0 new opportunities for an even closer ASEAN-China community with a shared future," features a high concentration of AI, business, innovation, and financial elements. It is not only an important platform for economic cooperation in the Asia-Pacific region but also a vivid practice of China and ASEAN countries upholding multilateral trade and building a community with a shared future. It sends a strong signal to the world of unity, cooperation, and common development.

In 2021, President Xi Jinping proposed the joint building of a peaceful, safe and secure, prosperous, beautiful and amicable home, charting the course for China-ASEAN cooperation. Today, China and ASEAN have become a model of regional cooperation marked by mutual support and shared destiny. The data speaks for itself. From January to August this year, trade between China and ASEAN reached $686.78 billion, an 8.6 percent year-on-year increase. As of July, two-way investment between the two sides exceeded $450 billion. The effect of visa-free policies has been significant - from January to August, the number of trips between China and ASEAN exceeded 25 million, up 11.2 percent year on year, truly deepening "hard connectivity" of infrastructure, "soft connectivity" of rules and standards and "heart-to-heart connectivity" between the people.

"The speech script is right in my glasses - you can't see it, but I can." At the opening ceremony, Chen Gang, secretary of the Communist Party of China Committee of the Guangxi Zhuang Autonomous Region, showcased a pair of smart glasses, one of the latest achievements of the China-ASEAN Artificial Intelligence Innovation Cooperation Center. This year's CAEXPO highlights AI empowerment and innovation. The 10,000-square-meter pavilions for artificial intelligence and new-quality productive forces not only witness the implementation of China-ASEAN bilateral agreements but also sketch out a blueprint for upgrading cross-border industrial chains. Through the platform of the CAEXPO, China and neighboring countries "share in real time" the fruits of high-tech development and provide inclusive AI benefit-sharing programs, injecting imagination into high-quality regional cooperation.

How popular is the CAEXPO? Just look at its "spin-offs." Two months before the event, the "AI for All: China-ASEAN" competition, dubbed "AI Super League" by the media, was already trending. From Nanning in Guangxi to Bangkok in Thailand and Kuala Lumpur in Malaysia, AI companies from China and ASEAN countries have been exploring new paths of cooperation. Coinciding with the CAEXPO's opening, high-level meetings such as the China-ASEAN Ministerial Roundtable on Construction and the China-ASEAN Meteorological Forum are also being held. From enabling "low-latency transmission" of meteorological data to jointly advancing "better housing" initiatives and the preservation of urban-rural historical culture, the CAEXPO and its "derivative platforms" continue to enrich and expand the connotations of the China-ASEAN "Nanning Channel."

How close is the cooperation between China and ASEAN? The results of their collaboration are the most convincing evidence. Over the past decade, high-quality Belt and Road cooperation has deepened, resulting in a consensus and documents for building a community with a shared future between China and eight ASEAN countries, including Laos and Cambodia. Emerging fields such as the digital economy and green economy have become new growth points for cooperation. Meanwhile, iconic connectivity projects like the China-Laos Railway and the Jakarta-Bandung High-Speed Railway have brought the construction of the China-ASEAN community with a shared future even closer. 

China and ASEAN countries are both part of the Global South, sharing a common pursuit of a better life and the goals of achieving Chinese modernization and modernization in Southeast Asian countries. This has led to a harmonious resonance in the process of expanding opening-up and promoting higher-quality cooperation. 

In the context of unilateralism and protectionism continuously impacting global supply chains, the convening of the CAEXPO has set a model for multilateral cooperation, openness, inclusiveness, and mutual benefit. This model is especially significant as it emerges in the Asia-Pacific region, which has a massive economy and the strongest growth vitality, providing encouragement for multilateral governance and the process of economic globalization. 

As one of the key activities of the CAEXPO, the ASEAN Plus Three (Japan-China-Republic of Korea) Industrial Chain and Supply Chain Partnering Conference will kick off on September 18 in Nanning, effectively promoting the complementary relationship between the resource industries of China, Japan, South Korea, and ASEAN, ensuring the security of supply chains, and injecting new vitality into regional economic integration.

The impressive achievements of China-ASEAN cooperation serve as the best evidence of the relationship being "the most successful and dynamic model of regional cooperation in the Asia-Pacific." With the comprehensive completion of the negotiations for the China-ASEAN Free Trade Area 3.0, this year's CAEXPO will empower a new future for China-ASEAN cooperation through AI empowerment and innovation, marking a new starting point for high-quality bilateral cooperation

China's quantum computing industry has made new progress. Recently, Chinese startup Origin Quantum in Hefei, East China's Anhui Province, launched Origin Tianji 4.0, a self-developed superconducting quantum measurement and control system that supports 500-plus-qubit quantum computers. The progress indicates that China's quantum computing industry has achieved replicable and iterative engineering production capabilities, laying the foundation for the mass production of hundred-bit quantum computers, Kong Weicheng, head of the system's development team, told the Global Times.

Dubbed the "nerve centers" of quantum computers, measurement and control systems manage precise signal generation, acquisition, and control for quantum chips. In 2018, Kong's team developed the first domestically produced quantum computer control system with completely independent intellectual property rights, filling a gap in the domestic quantum computing measurement and control field.

The latest Origin Tianji 4.0 system can effectively shorten the development and delivery time for quantum computers at the hundred-bit scale, while enhancing the system's automation capabilities and long-term stability, according to Kong, who is also deputy director of Anhui Quantum Computing Engineering Research Center.  

Previously, China relied heavily on imports for high-end instruments and equipment, and we could only use traditional commercial instruments to build our quantum computing measurement and control systems, with signal output and acquisition tasks being conducted separately. This approach was not only costly and redundant in functionality, but also had drawbacks such as poor compatibility and difficulty in integration, Kong told the Global Times. 

"Now, after multiple iterations, China's quantum computing measurement and control system has improved in terms of product scalability, integration, performance stability, and automation level. What we need to do is to go from nothing to something, and from something to a usable and durable product," Kong said. 

The Origin Tianjin 4.0 system was built and upgraded based on its preceding 3.0 version, which powers Origin Wukong, China's independently developed third-generation superconducting quantum computer. 

Since it went into operation on January 6, 2024, Origin Wukong has served users in 139 countries and regions over 26 million times, and completed more than 380,000 quantum computing tasks, covering a wide range of industries from finance to biomedicine, the Global Times learned from the team. 

According to Kong, in recent years, the process of quantum computing industrialization has been growing rapidly around the world. Eight years ago, Barclays Bank began to explore the application scenarios of quantum technology in the financial sector. Subsequently, leading international financial institutions such as JPMorgan Chase and Goldman Sachs formed quantum research teams to explore quantum computing applications.

Domestically, quantum computing has been explored in various industries, including national defense and security, biopharmaceuticals, energy materials, artificial intelligence, financial markets, and transportation and aviation. However, "there is still a significant gap from the industry's expectations for exponential acceleration and leaps in computing power," Kong said. 

According to Kong, the development of quantum computers is influenced by various factors such as hardware devices, cooling environments, and temperature, and these challenges require cross-disciplinary collaboration, including efforts in ecological construction and other dimensions. - Global Times In Depth

China has successfully established the world's first three-satellite constellation on the distant retrograde orbit (DRO) in the Earth-moon region of space, connecting them with stable inter-satellite measurement and communication links, Global Times learned from program developer the Chinese Academy of Sciences (CAS).  

Such development has yielded variety of original scientific and technology outcomes, laying a solid ground for the country's future development of the Earth-moon region of space and frontier exploration of the space science, the CAS disclosed in the statement it provided to the Global Times on Wednesday. 

Per the CAS, the Earth-moon region of space refers to the expanded domain extending outward from Earth's orbit, reaching up to 2 million kilometers from Earth. Compared to Earth's orbital space, its three-dimensional volume expands by more than a thousand times, the academy explained. 

Developing and utilizing cislunar space holds tremendous strategic significance for lunar resource exploitation, long-term human habitation beyond Earth, interplanetary activities, and the sustainable exploration of the solar system, it added. 

The CAS launched preliminary research and key technology development in this region in 2017. In February 2022, a pilot project was initiated to develop and launch three satellites to form a large-scale satellite constellation in the region of space, aimed at exploring the unique characteristics and application potential of the DRO.

The DRO-A and -B satellites were launched in March 2024, and entered their mission orbit on July 15 the same year, while the DRO-L was launched in February 2024 into a sun-synchronous orbit and began conducting experiments as planned. The three formed the constellation for the first time in August 2024. 

The plan included DRO-A satellite permanently staying in the DRO, while the DRO-B satellite operates in Earth-moon space maneuver orbits, according to CAS' Technology and Engineering Center for Space Utilization (CSU.)

Chinese scientists have made significant breakthroughs in ranging fields since the set-up of the three-satellite constellation in 2024.

Building on years of research in Earth-moon region of space astrodynamics and space exploration, the scientific team proposed an innovative design concept: trading longer flight time for increased payload capacity and greater contingency margin. As a result, the satellites completed Earth-moon transfer and achieved low-energy DRO insertion using only one-fifth of the fuel required by traditional methods, marking the world's first successful low-energy insertion into a DRO. 

This breakthrough significantly reduces the cost of accessing cislunar space, opening up new avenues for large-scale development and utilization.

The team also achieved another world-first by successfully verifying a 1.17-million-kilometer K-band inter-satellite microwave measurement and communication link, overcoming a major technological bottleneck in building large-scale constellations in cislunar space. 

In terms of space science, the mission has also supported astrophysical research such as gamma-ray burst detection and trialed new technologies, including operating atomic clocks.

Moreover, Chinese researchers successfully validated a new space-based orbit determination system whereby one satellite tracks another, replacing traditional ground-based tracking. Using just three hours of inter-satellite measurement data, they achieved orbit determination accuracy equivalent to over two days of traditional ground tracking. This breakthrough significantly lowers the cost of orbit determination for cislunar spacecraft, paving the way for more efficient operations.

Wang Wenbin, a researcher at CSU, hailed that this achievement marks the first time internationally that orbit determination was verified using satellite-to-satellite tracking rather than ground stations. 

"It's like turning a traditional ground station into a satellite and placing it in a low-Earth orbit," he explained. "This opens a new technical pathway for China's future cislunar and deep space exploration. It also provides an efficient solution for orbit determination, navigation, and timing across various cislunar orbits, supporting the future expansion of large-scale commercial activity in cislunar space."

Researchers told the Global Times on Wednesday that the program would support China's future lunar exploration mission, including providing space-based inter-satellite measurement for rapid orbit determination and autonomous navigation services for lunar exploration mission orbiters, and supply high-precision time signals for lunar surface facilities. 

Additionally, as the DRO is far from Earth and the moon, free from obstructions, it could facilitate the establishment of communication links with lunar exploration mission spacecraft, and assist in the downlink of critical or emergency data, researchers explained.

China has successfully established the world's first three-satellite constellation on the distant retrograde orbit (DRO) in the Earth-moon region of space, with the constellation operating stably for over 200 days, the Global Times learned at an academic seminar held by the project's developer, the Technology and Engineering Center for Space Utilization (CSU) at the Chinese Academy of Sciences (CAS) recently.

Apart from sharing this groundbreaking achievement, a particular detail discussed at the seminar attracted widespread attention: During the launch of two satellites in the three-satellite constellation - DRO-A and DRO-B - in March 2024, the mission once encountered anomalies. However, the situation was successfully navigated, under the 123-day dedicated efforts by the project's team at the center, with an average age of under 34.

What thrilling events unfolded during the rescue of the malfunctioning satellites, which were tens of thousands of kilometers away? What challenges did the program's team face and overcome? What significance does this launch hold for China's space endeavors and the development of humanity? The Global Times recently spoke with two participants from the project, who recounted how this young team turned a potential space disaster into a success. 

Anomaly in satellite launch

In mid-April, the CSU released images of a DRO-A satellite with its solar panel severely damaged.

The satellite, which is still operational, evokes Zhang Hao's memories of March 13, 2024. That evening, at 8:51 pm, China launched the DRO-A/B satellites using the Long March-2C carrier rocket with a Yuanzheng-1S (Expedition-1S) upper stage attached, from the Xichang Satellite Launch Center. It was a historic moment, marking China's first foray into the deep exploration of the DRO.

The DRO is a unique family of orbits between the Earth and the moon. A typical DRO is located around 310,000 to 450,000 kilometers from the Earth, or 70,000 to 100,000 kilometers from the moon. Compared to other orbits, the DRO offers greater stability, allowing spacecraft to remain in position for hundreds of years without frequent adjustments. It is regarded by the aerospace community as a "natural harbor in the Earth-moon space." Following the launch of the DRO-A/B satellites, they are expected to work in conjunction with the previously launched DRO-L satellite, to establish K-band microwave inter-satellite measurement and communication links.

"Together, they will form a lighthouse or a beacon for further deep space exploration by us," Zhang, a research fellow at the CSU, told the Global Times.

However, shortly after the launch that evening, news of an "anomaly during the DRO-A/B satellite launch" drew public attention: While the first and second stages of the rocket flew normally, the upper stage, which is directly responsible for placing the satellites in their designated orbit, experienced an anomaly, resulting in the satellites not reaching their intended trajectory. 

Zhang, responsible for orbital design and mission planning in this project, recalled details from that moment in the mission control center. At about 11 pm, signaling the imminent separation of the satellites from the rocket, the parameters representing the apogee height on the large screen suddenly fluctuated violently: The apogee height, which was supposed to steadily increase to 292,000 kilometers, instead oscillated like a roller coaster at just 150,000 kilometers.

Yin Yongchen, a third-year doctoral student at the University of the Chinese Academy of Sciences (UCAS), is one of the Gen Z members of the project team. That night, the 24-year-old, who was busy with the relevant Ground System and was not directly aware of the situation on-site, recalled that several dozen minutes had passed beyond the expected time of the separation [of the satellites from the rocket] without any updates. 

"I felt a vague sense of unease," he said. As midnight approached, Yin received a message from Zhang informing him that there was indeed a problem with the launch. "My heart sank at that moment."

In this project, Yin's role primarily involved assisting Zhang with contingency planning prior to the satellite launch. Now that an emergency had truly arisen, he realized that their upcoming tasks would be even more challenging.

Finally, after approximately 40 minutes of losing contact, the Telemetry, Tracking, and Command (TT&C) system captured a flickering signal. The team discovered that the DRO-A/B satellite duo had been "thrown" into an orbit at an apogee of only 134,000 kilometers - far below the intended 292,000 kilometers. 

Worse still, it was spinning at over 200 degrees per second at that time. 

"If these satellites did not regain their status within a few hours, their power may run out, or if they continued spinning at such high speeds, they would fall apart, become multiple pieces of space debris," Zhang told the Global Times. 

"We needed to quickly and efficiently find a solution and implement it before that happened," Zhang said.

Youth power


The project team made multiple adjustments to the trajectory of the DRO-A/B satellite constellation in the following months. This "space rescue" was officially declared a success on July 15, 2024, lasting 123 days. Later, on August 28, DRO-A and DRO-B were successfully separated.

The project team accomplished this remarkable feat, covering approximately 8.5 million kilometers, while consuming only one fifth of the fuel typically required for such missions. The space rescue not only salvaged satellites, but also validated several "world firsts," such as low-energy transfer for the DRO spacecraft, inter-satellite communication over a distance of 1.17 million kilometers, and a new system for space-based orbit determination.

Zhang, who participated in the satellite launch control process for the first time, reflected on the valuable experience he gained during the mission. "In this rescue, we collaborated closely with people from different institutions, and I accumulated a lot of practical experience," he said. "More importantly, the successful orbital insertion of the satellite is only a beginning, subsequent on-orbit technical breakthrough and scientific discoveries are waiting ahead of us."

According to Zhang, the three-satellite constellation, which includes DRO-A, DRO-B, and the previously launched DRO-L, is expected to serve as a guiding beacon and communication hub for future space navigation. It can also function as space laboratories due to its unique gravitational field. Moreover, in the future, the constellation may serve as infrastructure for lunar resource development, and even pave the way for information highways for Mars exploration.

Despite the significance of the mission, the team executing it is remarkably young. A millennial himself, Zhang noted that most team members are millennials. He praised the Gen-Z students involved in the project for their strong technical skills, sense of responsibility, and passion for aerospace research. "The system of integrating research and education of UCAS, or more broadly, our national education system, has laid the foundation for the Gen-Z students to deal with these situations".

Yin recalled the overwhelming sense of achievement and joy he felt when the rescue was officially declared successful. "As a student, being part of this rescue and witnessing this historic moment in China's space history, is something I take great pride in," he told the Global Times.

May 4 marks China's Youth Day. Yin said that there are more and more young people like him who are proud of China's great achievements in space exploration, with a dream of embarking on a journey "to the sea of stars," by joining the aerospace industry. "It is truly an honor for our younger generation to witness, and even contribute to, China's rise as a space power," he said.

Get through challenges

An emergency rescue effort on the ground was mounted. Challenges came one after another.  

The first challenge was to stop the spinning 581-kilogram DRO-A/B satellite duo. The project team repeatedly uploaded contingency commands, modifying parameter thresholds, alternately using the engines of each satellite to eliminate the spinning. In an attempt to "talk" to the satellites, the flight control team had to issue each command multiple times. By around 3 am the next day, the satellite duo successfully ceased its high-speed spinning.

Next came the second challenge. Telemetry data indicated that the solar panel of the DRO-A satellite could not lock, while the solar panel of the DRO-B satellite was completely "dislocated." As the power source for the satellites, any anomaly with the solar panels could lead to a critical power shortage, risking total energy depletion.

The team urgently implemented a series of operations, including uploading attitude control commands, and repeatedly adjusting the sun-pointing attitude. At last, they managed to successfully "recharge" the satellite with the damaged solar panels.

Having overcome these two major challenges, the real test was just beginning. At the time, the apogee altitude of the DRO-A/B satellites was less than half of what was expected, and fuel reserves were critically low.

How could the satellites be brought back on track? Within 40 hours, the team members engaged in heated discussions, scribbling formulas, coding, and repeatedly calculating a plan to return the satellites to their intended orbit amid the complex influences of various gravitational forces. During this period, Zhang and some colleagues hardly rested. "I was highly tense and concentrated, and didn't even feel tired," said Zhang.

Majoring in Astrodynamics, Yin participated in the review of orbital control parameters during this rescue. The task required meticulousness and patience. Yin recalled that each review of the orbital control parameters was time-sensitive, necessitating timely command uploads to the satellites. 

Under pressure, Yin made a slight error in setting the engine parameters, which delayed the successful review of the parameters. "I was quite anxious at that moment, worried that my mistake would hinder the normal execution of the mission," he told the Global Times. The issue was later promptly identified and resolved with the help of the team's veteran members.

Time passed during the tense yet orderly rescue operation. At 12:42 pm on March 18, 2024, nearly five days after launching the first contingency orbital control maneuver, the apogee altitude of the satellites was successfully raised to the intended height of about 240,000 kilometers, bringing a sigh of temporary relief to the entire team. A few days later, the project team conducted a second perigee orbital maneuver, successfully elevating the combination to around 380,000 kilometers.

Reflecting on the process of overcoming each challenge with his coworkers, Zhang described their overall demeanor as "busy yet composed." He mentioned that before satellite launching, they would brainstorm in advance about potential malfunctions, and prepare relevant countermeasures.

What is driving the acceleration of China’s unicorn enterprises

https://www.zgcforum.com.cn/uploads/2025-03-23/6ae305e1-a9af-4f3a-88d0-1f175799adde1742709825278.png

The China Unicorn Enterprise Development Report (2025), released at the Second Global Unicorn Company Conference, reveals that China currently has 409 unicorn enterprises with a total valuation of approximately $1.5 trillion. This accounts for nearly 30 percent of the global unicorn firms and ranking China second worldwide. At the same time, international capital is demonstrating its confidence in China's technological innovation and economic growth through concrete actions. Foreign media, including Fortune magazine, have noted the significant inflow of international capital into China, emphasizing the immense appeal of the country's tech companies and their innovative potential. These developments send an increasingly clear message to the world: walking alongside China means walking with opportunities, believing in China means believing in the future and investing in China means investing in tomorrow.  

In 2013, American venture capitalist Aileen Lee coined the term "unicorn" to describe tech startups valued at over $1 billion that are not listed on a share market, drawing inspiration from the mythical creature known for its rarity and value. While unicorn enterprises are no longer as scarce as they were a decade ago, they continue to represent highly innovative and fast-growing companies, widely regarded as key indicators of the latest technological revolutions and industrial transformations. Compared to the 369 unicorn enterprises listed in last year's report, the number and geographical distribution of Chinese unicorns have further expanded this year. Additionally, according to another report released last year, from 2016 to 2023, the number of unicorn enterprise sectors in China increased from 22 to 39, shifting from a focus on business model innovation to one increasingly driven by technological advancements. Unicorn enterprises are playing an increasingly prominent role in China's economic transformation and upgrading.

With breakthroughs in cutting-edge technologies such as artificial intelligence (AI), quantum computing and biotechnology, China's innovative tech enterprises undoubtedly are set to play an increasingly significant role in the global unicorn enterprise landscape. The deep integration of the digital and real economies, the construction of an innovation ecosystem, and the deepening of capital market reforms will all help more startups with disruptive innovation capabilities to quickly grow into unicorn enterprises. 

Moreover, what is becoming increasingly evident to the world is the value of China as a fertile ground for the growth of innovative technology enterprises. From the national level to local governments, a multi-tiered and comprehensive support system enables these enterprises to face market competition and unknown territories with greater confidence, allowing them to continuously catch up with and even lead the forefront of the world.

China's development approach, which focuses on handling its own affairs well, fundamentally ensures that the country's technological innovation remains a process of continuous self-breakthrough. Take unicorn enterprises as an example: The meeting of the Political Bureau of the CPC Central Committee last July called for strong and effective support for gazelle companies and unicorn firms and this year's two sessions reaffirmed this commitment, from which people see the momentum for development in China that demands urgent actions to seize every opportunity. While trade wars, regional conflicts, and climate disasters continue to challenge the international community, China has remained steadfast in its direction and is forging ahead on its chosen path.

China, with its massive market of over 1.4 billion people, has seen its tech companies innovate through competition, transforming people's lifestyles and, to some extent, redefining the era. Today, China's mobile payment, e-commerce, and sharing economy models have been widely studied in regions such as Southeast Asia, Africa, and Latin America. Breakthroughs in fields like 5G, AI, and biomedicine are also providing new options for optimizing global supply chains and improving healthcare. When China's convenient, efficient, and low-cost lifestyle leaves a deep impression on foreign vloggers visiting the country, and when DeepSeek amazes the world with the new opportunities brought by AI, people believe that this is far from the endpoint of "Made in China" reshaping global imagination.

There is a viewpoint that 2025 could be the year when Chinese tech firms stun the world. In fact, this serves as yet another higher starting point for the idea that "investing in China is investing in the future." Data shows that in the past five years, the return rate of foreign direct investment in China is around 9 percent, which is at relatively high level in the world. Additionally, China is actively addressing the issues faced by foreign enterprises operating within the country and is willing to share vast development opportunities. Looking back, there is a solid foundation for cooperation; looking forward, there are positive expectations for development. Oliver Zipse, chairman of the board of management of BMW Group, stated that as long as the spirit of cooperation is upheld, new growth potential will be unleashed, which reflects the common sentiment of both Chinese and foreign enterprises in the face of opportunities.

The way a country views technological development and competition often reveals its aspirations and character. From substantial investments of international capital to widespread enthusiasm for the global sharing of technological achievements, it is clear that open cooperation is a common desire among the people and a prevailing trend of the times. China will continue to demonstrate through action that technological innovation will further flourish in this vibrant land, as it not only has a vast market, strong policy support, and a dynamic talent ecosystem, but also a steadfast commitment to pursuing development in collaboration with the world.

Trump seeks to toughen Biden’s chip controls over China failed as China make AI cheap, ubiquitous, not controlled by any one country or company and is available for everybody

 

Trump seeks to toughen Biden’s chip controls over China, and ask key allies match China curbs the US has placed on American chip-gear companies. How will Japan and Netherland response to that? Can China's chip industry overtake the US?

Your scenario is already ex-post. Biden wanted to starve China of technology. He had bullied Japan and Netherlands into submission. They dared not sell to China whatever machines and components that Biden forbade.

Biden’s problem was he did not know what China was cooking and what it has in the pipeline. China has a huge talent pool. It is an innovation powerhouse. Its developments were fast and numerous. Instead of being the hunter, he ended up playing catchup to China’s developments, to its frequent announcements of products and innovations. I suppose this is what his Commerce Secretary Raimondo meant when on the last days of her office, she called the whole exercise a Fool’s Errand.

But Biden was determined that US shall be the AI leader. Nvidia is the US bellwether of AI. He barred it from selling high-end AI chips to China. Trump was sold to the idea that AI dominance requires rising computing power, and large investments of money for large returns. So, with great fanfare, the bosses of Softbank, OpenAI, and Oracle, announced the establishment of a $500 billion AI fund that will ensure US leadership is unassailable.

But, lo and behold, along come DeepSeek. It spent only $5.6 million to teach its R1 model, a tiny fraction of the cost incurred by OpenAI’s o1. It achieves this through algorithm efficiency and innovation than relying on high-end chips. It made it open-source and even has mini “distilled” versions to allow researchers with limited computing power to use the model. It up-ended completely the thesis of ever rising computing power, big investments, and big returns. US attempt to dominate AI is curbed, in all likelihood, permanently.

Can China’s chip industry overtake the US?

This is not the point.

China’s purpose is democratic. Take DeepSeek’s open-source. It could make AI cheap, ubiquitous, not controlled by any one country or company, and is available for everybody.

This is not to say powerful AI chips are unimportant. Only that it is not the whole story.

China is one generation behind the US. Huawei Ascend 910C equals Nvidia’s last generation H100. Its 920 due in a year matches Blackwell, the latest Nvidia’s chip.

China is also catching up with production. Two the new SMIC fabs that will onstream this year and next each has capacity of 50,000 wafer per month, more than enough to meet its needs. Huawei plans to produce 100,000 910C and 300,000 910B chips this year.

Digitimes Asia reported that the yield in the manufacture of 910C has doubled from 20% to 40%, and is profitable. The aim is to increase it to 60% this year to match the industry norms. The yield for the older 910B is 50%.
