Beijing: A rise in US visa denials for Chinese academics and intensified scrutiny of alleged links to Beijing over fears of potential espionage are having a chilling effect on long-standing research collaboration, researchers say.
American and Chinese scientists have co-authored thousands of papers each year, far outpacing the output from scientific collaborations between any other two nations, according to a 2018 survey by academic database Nature Index.But it is getting tougher for researchers to work together on projects and share data for peer review, as American institutions tighten rules for accepting foreign funding and intensify vetting of foreign partners, several researchers said.
