China is actively recruiting top American scientific talent, with at least 105 scientists leaving U.S. universities and corporations to join Chinese Communist Party-funded institutions since 2024. This influx of expertise aims to bolster China's ambitions in dominating critical fields like medicine, space, and technology.
Nearly half of these recent defectors are in biotechnology and medicine, indicating a concentrated effort by China to surpass the United States in medical innovation. Other specialists work in areas including space science, climate change, computers, and semiconductors.
Notable figures include Charles Lieber, former chair of Harvard's chemistry department, who was convicted in 2021 of lying about his ties to China. He has become the founding director of a research institute in Shenzhen, reportedly funded by the Chinese government, with a promised salary of $750,000 plus $150,000 in living expenses. His new lab focuses on developing AI super-soldiers, leveraging his decades of research at Harvard, which previously received significant funding from the U.S. Department of Defense.
Virologist Haitao Hu, who led vaccine development for major viral infections, including HIV, at a U.S. military research facility, left the University of Texas last December for the Chinese Academy of Sciences Institute of Microbiology. Similarly, Zhonghua Gao, a leading researcher in brain development and studies on autism and cancer funded by the National Institutes of Health, departed Pennsylvania State University's College of Medicine in January to join Shenzhen University of Advanced Technology.
Biologist Xianzhong Xu returned to China in May. He was previously affiliated with the University of Michigan, where four researchers from his lab were arrested a few months prior for allegedly conspiring to smuggle biological material. No evidence suggests Xu was involved in that scheme.
Omar Yaghi, a recipient of last year's Nobel Prize in chemistry for his work on sponge-like materials for water and gas capture, left the University of California Berkeley earlier this month for Tsinghua University in Beijing. He is now leading an institute focused on accelerating new material discovery using artificial intelligence.
Astrophysicist Liang Dai, who studies black holes and was a Sloan Research Fellow, moved from Johns Hopkins University to Fudan University this spring.
Experts suggest China's aggressive recruitment is a strategic move to gain an advantage over the U.S. in the global competition for scientific talent. "Both China and the United States recognize that the battlelines being drawn in the global war for scientific talent are critical for national security," said Jack Burnham, senior research analyst at the Foundation for Defense of Democracies' China Program. He noted that factors such as "paralyzed federal science funding, concerns over immigration status for foreign workers and students at US universities, and its own pool of increasingly cutting-edge researchers" may be contributing to China's success in luring talent.
China has been investing heavily in research and development, particularly in pharmaceuticals, and has surpassed the U.S. in clinical trial volume since 2024. Dr. Roberta Shapiro, professor at Columbia University Medical Center, suggested that some scientists are attracted to China due to perceived greater freedom to advance treatments, contrasting it with regulatory restrictions in the U.S.
The FBI has previously warned that Chinese talent programs are part of a broader effort to acquire foreign technology and expertise to advance China's strategic and military objectives. FBI counterintelligence assistant director John Brown stated that "the Communist government of China has proven that it will use any means necessary to advance its interests at the expense of others" to erode U.S. competitive advantages and become a global superpower.
