The Trump administration announced sanctions on Thursday aimed at Chinese Communist Party officials whom the United States believes have been involved in carrying out human rights abuses against Uighurs and other minorities in China.

The Treasury Department’s Office of Foreign Assets Control revealed the sanctions against a Chinese Communist Party entity and four Chinese Communist Party officials “in connection with serious rights abuses against ethnic minorities” in the Xinjiang Uyghur Autonomous Region in western China. These designations under the Global Magnitsky Human Rights Accountability Act include XUAR Chinese Communist Party Secretary Chen Quanguo and former XUAR Deputy Party Secretary Zhu Hailun. The Xinjiang Public Security Bureau was also targeted by U.S. sanctions, and the U.S. also designated XPSB Director and Communist Party Secretary Wang Mingshan and former XPSB Party Secretary Huo Liujun.
