The U.S. and China are collaborating less on projects across scientific disciplines amid a culture of fear in both countries
China’s scientific collaboration with other countries has declined since the pandemic, driven by falling partnerships with the United States, an analysis shows.that political tensions between China and the United States, combined with the pandemic, have affected research collaborations between the two countries. But it takes time for evidence of this sort of decline to accumulate in research databases.’s news team is editorially independent of its publisher, Springer Nature.
The drop in internationally co-authored papers is mainly due to China’s declining share of papers published with US researchers, which fell by 6.4% between its peak in 2017 and 2023 — the largest decline of any country included in the analysis. The findings were presented at the Zhongguancun Forum in Beijing on 25 April.
The crackdown on perceived foreign interference in both the United States and China is making researchers more cautious about collaborating, says Zhang. Restrictive policies and the climate of fear could end up driving talent away from certain countries and fields, leading to a “brain drain and a loss of valuable human capital”, she says.
