US Treasury Secretary Janet Yellen last week wrapped up a four-day visit to China on a note of cautious goodwill signalling progress in relations following a summit between US President Joe Biden and Chinese President Xi Jinping in California in November last year. It is unclear whether Ms Yellen’s visit, which followed a phone chat between Messrs Xi and Biden the week before, will yield concrete policy actions immediately, though her down-to-earth style, enthusiasm for Chinese food, and dexterity with chopsticks earned her generous praise from the state-controlled media. But the timing of the visit, her second in nine months, is significant. The Biden administration is nearing the completion of a review of whether to renew duties imposed in 2018 by Donald Trump on Chinese imports worth billions of dollars. The US has also restricted China’s access to advanced semiconductor and other technology, saying it could be used for military purposes. At the same time, the slowing Chinese economy has prompted a rethink in Beijing. Late last month, US business leaders attending the annual China Development Forum met Mr Xi as part of the Chinese administration’s efforts to boost foreign investment.
