Chinese-Born Fields Medal Winners Reignite Debate Over China’s Research System

Two Chinese-origin mathematicians, Hong Wang and Yu Deng, became the first pair of mathematicians of Chinese heritage to jointly receive the Fields Medal, widely regarded as the “Nobel Prize of mathematics,” the BBC reported. 

Wang and Deng received the award alongside American mathematician John Pardon and Canadian mathematician Jacob Tsimerman. Each recipient received a prize of CAD $15,000 (approximately 72,000 yuan RMB).

The groundbreaking achievement generated widespread attention on Chinese social media platforms. Topics such as “Fields Medal” and “Chinese mathematicians win Fields Medal for the first time” attracted millions of views on platforms including Weibo and Xiaohongshu (Little Red Book). Many users described the achievement as “a source of pride for Chinese people.”

However, while celebrating the accomplishment, a deeper question has also drawn attention: Why did these top mathematicians achieve the highest recognition in global mathematics only after leaving China and entering research systems in the United States and Europe?

From a Chinese prodigy to the pinnacle of global mathematics

Hong Wang was born in 1991 in Guilin, Guangxi, China. She demonstrated extraordinary mathematical talent from an early age. During primary school, she skipped grades, and at the age of 16, she entered Peking University.

Initially, Wang chose to study earth sciences, but after one year she transferred to the Department of Mathematics. After graduation, she pursued further studies at Paris-Sud University in France and the École Polytechnique, eventually earning her Ph.D. from the Massachusetts Institute of Technology (MIT) in the United States.

Today, Wang is a professor at New York University (NYU) and also a permanent professor at the Institut des Hautes Études Scientifiques (IHES) in France.

She received the Fields Medal for solving the “Kakeya conjecture,” a problem that had challenged mathematicians for more than a century.

In 1917, Japanese mathematician Soichi Kakeya proposed the following question: If a pencil rotates around in space, what is the smallest possible area swept out by its movement?

Wang and American mathematician Josh Zahl made a breakthrough by studying the geometric structures involved in three-dimensional space and published their related research last year.

Wang told Agence France-Presse (AFP) that the reason the problem has attracted mathematicians is that similar phenomena naturally appear across multiple different areas of mathematics.

Another Fields Medal recipient, Yu Deng, is a professor of mathematics at the University of Chicago. He solved Hilbert’s Sixth Problem, proposed by German mathematician David Hilbert in 1900. 

The problem asks: How can the laws governing the motion of microscopic particles be used to derive and explain the behavior of the macroscopic world?

Deng Yu made a breakthrough on this century-old problem by studying the laws governing the motion of gases. He said that being placed alongside the great mathematicians he had long admired was “a tremendous honor.”

Behind major mathematical breakthroughs: The role of US and European research systems

It is worth noting that although both laureates were born in China, their academic and research journeys have been highly internationalized.

Both Wang Hong and Deng Yu studied at Peking University, but later chose to pursue their careers overseas. Wang went to MIT for her doctoral studies, while Deng moved to the United States and earned his Ph.D. from Princeton University. Both eventually established their academic careers at leading American universities.

This has sparked discussion about China’s model for cultivating scientific talent.

International science publications such as The Economist and Nature have repeatedly pointed out that China’s investment in scientific research has grown rapidly in recent years, and the country now ranks among the world leaders in the number of academic papers published. However, in fundamental scientific fields—particularly areas such as mathematics and theoretical physics, which require long-term independent exploration—universities in the United States and Europe continue to maintain strong appeal.

The reason is not only funding, but also the research environment. The U.S. university system has long emphasized academic freedom, international collaboration, and researchers’ autonomy in choosing their fields of study. Fundamental mathematics research often requires decades or even a lifetime of accumulation and does not necessarily produce immediate economic returns.

Many top Chinese students receive strong mathematical training during their undergraduate years, but during the doctoral stage and throughout their research careers, they often choose the United States or Europe because these regions offer a more established ecosystem for basic research.

Beijing promotes a ‘science and technology powerhouse,’ but faces challenges in attracting overseas talent back

Chinese official media gave extensive coverage to the two mathematicians’ Fields Medal achievements, presenting them as an important symbol of China’s rising strength in mathematics.

However, the achievements have also highlighted a persistent challenge: while China has expanded investment in science and technology and emphasized becoming a global scientific power, attracting and retaining top overseas research talent remains a major issue.

Chinese mathematician Shing-Tung Yau—the first Chinese-born mathematician to receive the Fields Medal— told BBC that the Chinese mathematical community had been waiting for this moment for decades.

At the same time, Beijing has in recent years launched a series of talent recruitment programs aimed at attracting overseas scientists back to China, including the “Thousand Talents Program” and the National Overseas High-Level Talent Recruitment Program.

However, critics argue that the fundamental issue is this: if scientific talent was nurtured in an open and free research environment overseas, then what truly attracts them back is not only funding and laboratory facilities, but also academic freedom, institutional conditions, and long-term opportunities for stable development.

Some overseas Chinese scientists have said that while China’s research infrastructure and funding have improved rapidly in recent years, basic research still requires a more open academic culture.

‘Scientific democracy’ and the competition for talent: Institutional challenges facing China’s model

In recent years, China has promoted the goal of becoming a “scientific and technological powerhouse” and emphasized that technological development should serve national strategies. Some official commentary has described attracting overseas talent as part of the concept of “scientific democracy” or a vision of global talent sharing.

However, Western observers argue that the real competition for talent is not merely about providing research funding—it is also a competition between institutional environments.

They point out that future strategic fields such as artificial intelligence, biotechnology, and fundamental mathematics require not only national investment, but also an environment that allows scientists to explore freely, challenge existing ideas openly, and make independent judgments.

After learning that Hong Wang had received the Fields Medal, French President Emmanuel Macron called to congratulate her and wrote on social media that she represented the excellence of France’s research and education system. He also encouraged more scientists to choose France.

This episode highlights the reality of global competition for talent: countries around the world seek to attract top scientists, but what ultimately determines whether talent stays long term is often not simply the size of laboratories or the amount of funding, but the level of research freedom and the quality of the institutional environment.

The success of the two Chinese mathematicians is not only a triumph of individual talent, but also a result of the international scientific research ecosystem.
