On the last day it could, the Trump State Department officially declared that the Peoples’ Republic of China is committing “genocide” in Xinjiang Province against the mostly Sunni Muslin Uighr minority, the previously dominant group in the province. New SecState Antony Blinken has publicly stated that he agrees with this judgment. However, reportedly the State Department is reviewing this decision, as it is doing with many other parts of US foreign policy, including such things thought to be fairly straightforward such as rejoining the JCPOA nuclear agreement with Iran that Biden ran on rejoining and should. So whether or not this last minute action by Pompeo at State remains official or not is up in the air at the moment.
There is no question that the PRC’s policy towards the Uighurs is simply awful, not remotely defensible. Ir involves having large numbers of people in reeducation camps as well as lots of torture. This is combined with the more general program of simply having Han people fully dominating the province, which parallels a similar program in Tibet, although somehow currently the central government is not engaging in quite as unpleasant programs regarding the native ethnic Tibetan population as is happening regarding the Uighurs.
