American and Chinese scientists are decoupling, too

THERE ARE lots of ways to measure China’s rise. It is the world’s second-biggest economy, its biggest manufacturer and its biggest creditor. In 2021 it passed another milestone. That year, for the first time, Chinese scientists published more papers than their counterparts in America or the European Union (see chart 1). It is not just the quantity that is improving. The Index, run by the publishers of the journal of the same name, tracks contributions to the world’s best-regarded health and natural-sciences journals. Chinese researchers rank first in the natural sciences, and second overall.Cause for celebration, no doubt, in Beijing. In Washington, though, the news may have been less welcome. America is increasingly dismayed by China’s rise—and especially its growing scientific and technological prowess. Under Donald Trump, the previous Republican president, and Joe Biden, the current Democratic one, it has imposed tariffs, rules and subsidies designed to hobble China’s high-tech firms while boosting its own. China has retaliated, moving against some big American tech companies. Twenty years ago, politicians endorsed globalisation and free trade. Now “decoupling”, national security and “friend-shoring” are the hot topics.
