The U.S has blacklisted 28 Chinese companies from purchasing any American products for being implicated in human rights violations and other abuses in China's Xinjiang region.
The U.S Department of Commerce said the action constricts the export of items subject to the Export Administration Regulations (EAR) to entities that have been implicated in human rights violations and abuses in China's campaign targeting Uighurs and other predominantly Muslim ethnic minorities in the Xinjiang Uighur Autonomous Region.
"The U.S Government and Department of Commerce cannot and will not tolerate the brutal suppression of ethnic minorities within China, Secretary of Commerce Wilbur Ross said.
"This action will ensure that our technologies fostered in an environment of individual liberty and free enterprise are not used to repress defenseless minority populations, he said.
Located in Xinjiang Uighur Autonomous Region and throughout China, these entities have all been implicated in the implementation of China's campaign of repression, mass arbitrary detention, and high-technology surveillance, the Department of Commerce said.
The entity list identifies persons or organisations reasonably believed to be involved, or to pose a significant risk of being or becoming involved, in activities contrary to the national security or foreign policy interests of the U.S.
