“…In 2018, US authors of science and engineering articles collaborated most frequently with partners from China (25.71%), and vice versa (43.65%) (NSB, 2019). The trend of weakening collaboration between China and the US since 2017 has already been identified (Zhu et al, 2021; Jia et al, 2022; Crow, 2022a; Baker, 2022), and the number of researchers with dual US–China affiliations is falling (Noorden, 2022). Studies have also shown that the US has benefited significantly from such partnerships (Lee and Haupt, 2020), and strategies requiring US allies to ‘decouple’ from China in key fields of R&D will potentially hurt ‘Five Eyes’ partners far more than either the US or the European Union (Flagg et al, 2021).…”
