Video surveillance company Hikvision said the USA listing had "no factual basis". On Tuesday, the company said that there were "no changes" to those plans, although a banker close to the situation was skeptical.

The possibility, nearly particular to draw a intelligent response from Beijing, targets 20 Chinese public security bureaus and eight corporations including video surveillance firm Hikvision, in addition to to leaders in facial recognition abilities SenseTime Neighborhood Ltd and Megvii Technology Ltd. A New York Times investigation in April found the Chinese government was using a huge network of facial recognition software to track Uighur people, and named all three companies as participants in the programme.
The US government has added eight firms specialising in facial recognition to the so-called "entity list" of foreign firms which are banned from trading with US companies.
Washington is adding 28 Chinese companies, government offices and security bureaus to a United States blacklist over their alleged role in facilitating human rights abuses in China's Xinjiang region.
"In Xinjiang, the Chinese government prevents Muslims from praying and reading the Quran, and it has destroyed or defaced a great number of mosques", Sullivan said. China counters that the "vocational training centres" combat extremism.

"The US Government and Department of Commerce can not and will not tolerate the brutal suppression of ethnic minorities within China", Commerce Secretary Wilbur Ross said.

Some of the firms added to the list trade on Chinese exchanges, which weren't open yet when the announcement was made in the U.S. "It now looks less likely".
China's Vice Premier Liu He and U.S. Trade Representative Robert Lighthizer are expected to meet on Thursday for the latest high-level talks aimed at resolving the dispute.
Ross said Monday's action will ensure USA technologies "are not used to repress defenseless minority populations".
