The US House of Representatives has passed a bill to counter what it calls the “arbitrary detention, torture, and harassment” of Uighur Muslims in China.
The bill calls for “targeted sanctions” on members of the Chinese government – and names the Communist Party secretary in the Xinjiang autonomous region, Chen Quanguo.
The bill still needs to be approved by the Senate and President Trump.
China’s foreign ministry reacted angrily, calling the bill “malicious”.
The passing of the bill comes days after Mr Trump signed into law a bill that supports pro-democracy protesters in Hong Kong – leading to condemnation from China.
