Mr Xi, meanwhile, issued a warning to Mr Biden that US support for Taiwanese independence was like "playing with fire.... and those who play with fire will get burned", according to Chinese state media quoted by Reuters. The White House said that President Biden "underscored that the United States remains committed to the 'One China' policy". "[It] strongly opposes unilateral efforts to change the status quo or undermine peace and stability across the Taiwan Strait."
The One China policy is a cornerstone of Sino-US relations. Under this, the US recognises and has formal ties with China rather than the island of Taiwan, which China sees as a breakaway province to be reunified with the mainland one day.
