The US government has blacklisted 28 Chinese companies, including some of the world’s most valuable AI startups, for being complicit in China’s effort to crackdown on its Uyghur Muslim population.

The majority of China’s Muslim population live in Xinjiang, a Northwestern region in between Kazakhstan and Mongolia. Millions of Uyghurs have been subjected to constant surveillance and thrown into internment camps.
