Video surveillance company Hikvision said the US listing had “no factual basis.”
“(We) call on the US government to re-examine based on the principle of fairness, justice and non-discrimination, and remove Hikvision from the entity list,” it said.
Artificial intelligence firm Megvii, which is backed by e-commerce giant Alibaba, said in a statement it “strongly” protests against the decision, which it said “reflects a misunderstanding of our company.”
Megvii said only one percent of its revenue in 2018 was from projects in Xinjiang, while no revenue at all was generated from the region in the first six months of 2019.
AI company SenseTime said it was “deeply disappointed” and would “work closely with all relevant authorities to fully understand and resolve the situation.”
The blacklisting of the companies follows Washington’s earlier move to stop technology giant Huawei and other Chinese firms from obtaining government contracts.
Hikvision was also included in that ban, which will preclude any US federal agency from purchasing telecom or technology equipment from the firms and comes amid concern that Huawei is linked to Chinese intelligence.
The US fears that systems built by Huawei could be used by Beijing for espionage via secret “backdoors” built into telecom networking equipment.
