China, US diplomats in Brazil tussle on Twitter over Xinjiang
- Chinese ambassador hits back over claims of sterilisations in far western region and payments to scientists at American universities
- Dispute echoes larger disagreements between the two countries

On Saturday, the US embassy’s Twitter account quoted FBI director Christopher Wray accusing China of paying scientists at American universities “to secretly bring our knowledge and innovation back to China – including valuable research, funded by the federal government”. It added: “Is this happening in Brazil?”
Chinese ambassador Yang Wanming reacted on Sunday, with a tweet which read “this man comes to Brazil with a special mission, which is to attack China with rumours and lies. We advise you to stop doing activities of this kind … An ant tries to knock down a giant tree, ridiculously exaggerating its ability.”
In March, Congressman Eduardo Bolsonaro, the president’s son, blamed China for the pandemic, prompting the Chinese ambassador to respond that his words were “an evil insult against China and the Chinese people”.
