China and the US are set to resume trade talks in Washington on Thursday against a backdrop of heightened diplomatic tension.
This week the US government blacklisted 28 Chinese entities it said were “implicated” in human rights abuses.
The US also imposed additional visa restrictions for Chinese government officials.
Without progress, the US will increase tariffs on $250bn worth of Chinese goods from 25% to 30% next Tuesday.
The latest diplomatic disagreement could complicate the talks.
Although many of the blacklisted entities are government security bureaus, the eight companies named include some of China’s leaders in artificial intelligence.
The blacklist could restrict the access of those companies to US microchips, which they currently rely on for many of their products and services.
