Human-rights groups and the United Nations are using Saturday’s two-year anniversary of a landmark U.N. report to call for action on the document which said that China may have committed crimes against humanity in the Xinjiang region.

U.N. High Commissioner for Human Rights Michelle Bachelet released the report on Aug. 31, 2022, just minutes before her four-year term ended.

China has vigorously denied any abuses in Xinjiang and issued a 131-page response to the report defending its record. Foreign Ministry Spokesperson Lin Jian said this week that China fully protects the rights of all ethnic groups.

The 2022 report said the extent of arbitrary and discriminatory detention of Uyghurs and other Muslims in the western Xinjiang region may be an international crime.
