China on Sunday said it will take “necessary measures” to respond to the U.S. blacklisting of Chinese companies over their alleged role in abuses of Uyghur people and other Muslim ethnic minorities, AP reported.
The Commerce Ministry said the U.S. move constituted an “unreasonable suppression of Chinese enterprises and a serious breach of international economic and trade rules.”
China will “take necessary measures to firmly safeguard Chinese companies’ legitimate rights and interests,” the ministry's statement said.
No details were given, but China has denied allegations of arbitrary detention and forced labor in the far western region of Xinjiang and increasingly responded to sanctions against companies and officials with its own bans on visas and financial links.
The U.S. Commerce Department said in a statement Friday that the electronics and technology firms and other businesses helped enable “Beijing’s campaign of repression, mass detention and high-technology surveillance” against Muslim minorities in Xinjiang.
The penalties prohibit Americans from selling equipment or other goods to the firms. 
The U.S. Commerce Department said 14 companies were added to its Entity List over their dealings in Xinjiang, and another five for aiding China's armed forces.
