WASHINGTON (Reuters) – U.S. President Donald Trump plans to sign legislation calling for sanctions on Chinese officials responsible for oppressing Uighur Muslims, a source familiar with the matter said on Monday without offering a time frame for the signing.

The bill, which passed the U.S. House of Representatives and the Senate with bipartisan support last month, calls for sanctions against those responsible for repression of Uighurs and other Muslim groups in China’s Xinjiang province, where the United Nations estimates more than a million Muslims have been detained in camps.

The Chinese embassy in Washington repeated a prior statement noting that the bill “blatantly smears China’s counterterrorism and deradicalization measures and seriously interferes in China’s internal affairs,” which China “deplores and firmly opposes.”

“We urge the US to immediately rectify its mistake, stop using Xinjiang-related issues to intervene in China’s internal affairs and refrain from going even further down the wrong path,” the embassy added.

The bill’s progress comes amid growing tensions between Washington and Beijing over the coronavirus pandemic’s origins and a recent Chinese bid to curb Hong Kong freedoms via a new national security law. China denies mishandling the outbreak and has said the United States should stop interfering in Hong Kong and Chinese affairs.

Trump said last week he was not considering imposing sanctions on Chinese President Xi Jinping personally over Beijing’s push to impose the legislation in Hong Kong. But the Republican president recently ordered his administration to begin eliminating special U.S. treatment for Hong Kong to punish China, and said Washington would also impose sanctions on individuals seen as responsible for “smothering – absolutely smothering – Hong Kong’s freedom.”

The Uighur legislation, proposed by Republican Senator Marco Rubio, singles out Xinjiang’s Communist Party secretary, Chen Quanguo, a member of China’s powerful Politburo, as responsible for “gross human rights violations” against them.

Bloomberg earlier on Monday reported news of the bill’s signing.
