The BBC’s China correspondent John Sudworth said – if it became law – the bill would mark the most significant international attempt to pressure China over its mass detention of Uighurs and other Muslim minorities.
It also accuses China of “systematically discriminating” against Uighurs by “denying them a range of civil and political rights, including the freedoms of expression, religion, movement and a fair trial”.
The bill details some of the policies allegedly carried out by China against Muslims in Xinjiang.
Pervasive, high-tech surveillance – including the collection of DNA samples from children
The use of QR codes outside homes to gather information on how frequently individuals pray
Facial and voice recognition software and “predictive policing” databases
The Uighur bill calls for sanctions on Chinese officials who are “credibly alleged to be responsible for human rights abuses in Xinjiang”.
It also names Mr Chen, who has been dubbed the “architect” of the camps.
The bill calls on Mr Trump to “condemn abuses” against the Uighurs, for China to immediately close all the camps, and to “ensure respect for internationally-guaranteed human rights”.
Republican Thomas Massie, from Kentucky, voted against the Uighur bill. He also voted against the Hong Kong bill.
China, which denies any mistreatment of Uighurs, said the bill was an affront to its policies in Xinjiang and amounted to interference in its internal affairs.
“This bill deliberately smears the human rights condition in Xinjiang, slanders China’s efforts in de-radicalization and counter-terrorism, and viciously attacks the Chinese government’s Xinjiang policy,” a foreign ministry statement said.
It said the policy in Xinjiang was “about fighting violence, terrorism and separatism”, adding that “thanks to those efforts, Xinjiang hasn’t seen a single terrorist attack over the past three years”.
The statement also said “the international community speaks highly of China’s Xinjiang policy”.
China also reacted angrily to the Hong Kong bill – suspending visits by US Navy ships and aircraft to Hong Kong, and issuing sanctions against US-based human rights groups.
In contrast, the World Uyghur Congress (WUC), a human rights group, hailed the bill for rebuffing what it called “China’s continued push of extreme persecution” in Xinjiang.
Dilxat Raxit, spokesman for the WUC, said the organisation looked forward to President Trump signing the bill into law.
