China’s Foreign Ministry on Saturday announced the assets of two Canadian human rights groups have been frozen in retaliation for their advocacy on behalf of the oppressed Uyghur Muslims and Tibetans.

The two Canadian entities affected by China’s sanctions are the Uyghur Rights Advocacy Project (URAP) and the Canada Tibet Committee. Twenty members of the two organizations were listed by name, 15 of them from URAP.

The regime in Beijing said both groups will be prohibited from doing business with Chinese organizations or individuals, and members of the Canadian groups will be barred from traveling to China, Hong Kong, or Macau.
