Chinese scientists living in the United States have for decades contributed to research efforts driving developments in advanced technology and science. But a growing number of them may now be looking elsewhere for work, as deteriorating geopolitical relations fuel extra scrutiny of Chinese researchers and Beijing ramps up efforts to recruit and retain talent. Between 2010 and 2021, the number of Chinese scientists leaving the United States has steadily increased, according to new research published last month. If the trend continues, experts warn that the brain drain could deal a major blow to U.S. research efforts in the long run.

“It’s absolutely devastating,” said David Bier, the associate director of immigration studies at the Cato Institute. “So many of the researchers that the United States depends on in [the] advanced technology field are from China, or are foreign students, and this phenomenon is certainly going to negatively impact U.S. firms and U.S. research going forward.”

From semiconductor chips to artificial intelligence, technology has been at the forefront of U.S.-China competition, with both Washington and Beijing maneuvering to strangle each other’s sectors. Cooperation, even in key sectors like combating climate change, has been rare.

From 2010 to 2021, the number of scientists of Chinese descent who left the United States for another country has surged from 900 to 2,621, with scientists leaving at an expedited rate between 2018 and 2021, according to research published in the Proceedings of the National Academy of Sciences (PNAS). Nearly half of this group moved to China and Hong Kong in 2010, the study said, and a growing percentage of Chinese scientists have relocated to China over the years.

While this number represents a small fraction of the Chinese scientists in the United States, the uptick reflects researchers’ growing concerns and broader apprehension amid a tense geopolitical climate. After surveying 1,304 Chinese American researchers, the report found that 89 percent of respondents wanted to contribute to U.S. science and technology leadership. Yet 72 percent also reported feeling unsafe as researchers in the United States, while 61 percent had previously considered seeking opportunities outside of the country.
