The US government has blacklisted 28 Chinese organizations for their alleged involvement in perpetrating systematic abuses against the Uyghur Muslim minority residing in the country’s Xinjiang province.

To that effect, eight technology companies have been added to the Entity List — including Dahua Technology, Hikvision, IFLYTEK, Megvii Technology, Sense Time, Xiamen Meiya Pico Information Co. Ltd., Yitu Technologies, and Yixin Science and Technology Co. Ltd. — effectively prohibiting them from trading with US companies.
