(Bloomberg) -- The U.S. will add eight more Chinese companies including top drone maker DJI and AI giant Megvii Technology Ltd. to an investment blacklist for alleged involvement in surveillance of the country’s Uyghur minorities, the Financial Times reported, citing two people briefed on the move.

The eight, which also include supercomputing giant Dawning Information Industry Co. or Sugon and Yitu Technology, will join the Treasury Department’s list of sanctioned Chinese military-industrial complex companies on Thursday, the FT said. American investors are barred from investing in companies bearing that label. The companies named were already on a separate blacklist that bans them from accessing American technologies.

The move comes days after Washington sanctioned SenseTime Group Inc. over the alleged oppression of Uyghur Muslims in the Xinjiang autonomous region, forcing the AI leader to postpone its Hong Kong IPO. It threatens to escalate tensions between Washington and Beijing, who are tussling over everything from technology supremacy to human rights.

Secretary of State Antony Blinken, who is touring Asia this week, criticized China’s “aggressive actions” in the region on Tuesday while laying out plans to more closely integrate U.S. allies and security partners.
