Trade war: 14 more Chinese companies blacklisted by US

However, Beijing denied the alleged abuses.

In the latest statement, the US Commerce Department said the companies had been "implicated in human rights violations and abuses in the implementation of China's campaign of repression, mass detention, and high technology surveillance against Uyghurs, Kazakhs, and other members of Muslim minority groups in the Xinjiang Uyghur Autonomous Region."

The latest blacklisted entities include: China Academy of Electronics and Information Technology; Xinjiang Lianhai Chuangzhi Information Technology; Shenzhen Cobber Information Technology Co; Xinjiang Sailing Information Technology; Beijing Geling Shentong Information Technology; Shenzhen Hua'antai Intelligent Technology; and Chengdu Xiwu Security System Alliance.

The action follows its decision last month to add five other companies and other Chinese entities to the ban over allegations of forced labour in the far western region of China.
