The violations identified in the latest study include torture, mass detention, and religious persecution.
According to Human Rights Watch’s World Report for 2022 China expanded its repression of ethnic minorities in Tibet and Xinjiang in 2021, severely restricting religious freedom and implementing coercive assimilationist tactics aimed at producing an unified national identity.
State actions in Xinjiang, in particular, constituted crimes against humanity.

Abuses included widespread detention and enforced disappearances.
Torture, mass surveillance, cultural and religious persecution, forced labor, and family separation were also reported by the rights group, which added that information flows from the region had been largely suppressed during the year.
“Authorities maintained tight control over information, [and] access to the region, already blocked, was further constrained due to COVID-19 movement restrictions,” HRW said.
Some Uyghurs detained by police were confirmed to be imprisoned, “including famed professor Rahile Dawut, albeit her stated offense, sentence length, and place of jail remained unclear,” according to the report.
“There were also reports of Uyghurs dying in detention, including biotech researcher Mihriay Erkin, 31, businessman Yaqub Haji, 45, and poet and publisher Haji Mirzahid Kerimi, 82,” HRW said.
