The number of scholars who declare affiliations in both China and the United States on research papers has dropped by more than 20% over the past 3 years, an analysis conducted for Nature has found. That slump seems to be part of a pattern of waning US–China collaboration that is starting to show up in research databases. The number of papers that were collaborations between authors in the United States and China — the world’s two largest research producers — also fell for the first time last year.
