Huawei has been found guilty of surveillance of Uighurs. Tencent has been found guilty. The UN had to push them out of the 75th UN anniversary because of that. Human rights groups raised concerns. The i5 Tech is also involved in Canadian universities, including Queen's and York. So is Hikvision, a facial recognition technology company, that got a major deal with the European Parliament to put in facial recognition cameras to detect COVID heat from people's bodies. It turns out they were involved. The EU had to cancel that program and that budget because the company was involved in monitoring the Uighurs as well. It's pretty expansive.
