Huawei worked on several surveillance systems promoted to identify ethnicity, documents show

Huawei and its partners have provided some of these surveillance products to authorities in the northwest Xinjiang region, where the Chinese Communist Party has sought for decades to control and assimilate the Uighurs, a Turkic ethnic minority, most recently through a massive "reeducation" program. Among them, according to documents from Huawei's website, was a facial recognition system used by police in the Xinjiang capital Urumqi, and a highway surveillance camera system for the region.
