A decent post on the topic (CW: r*ddit). The meatiest parts:

Approximately 50% of what you hear is outright propaganda, as we know the CIA’s affiliates churn out. We also see CIA assets pushing narratives on Reddit. The next 25% is poorly researched speculation by an evangelical end-timer, and the final 25% is an accurate description of the PRC’s response to far right, religious terrorism and separatism.

First, let’s just establish using safe, American sources that a bunch of Uyghur people went to fight with ISIS in Syria, then returned. Let’s also establish that there have been consistent terrorist attacks with significant casualties and that the CIA and CIA front-groups have funded and stoked Islamic extremism across the world for geopolitical gain.

Now, we need to consider potential responses.

The CPC could give up and surrender Xinjiang to ISIS. This option condemns millions of people to living under a fundamentalist Islamic State, including many non-Muslims and non-extreme Muslims. This option creates a CIA-aligned state on the border, and jeopardises a key part of the Belt and Road initiative, which is designed to connect landlocked countries for development and geopolitical positioning. This option also threatens the CPC’s legitimacy, as keeping China together is a historical signifier of the Mandate of Heaven.

The next option is the American option. Drone strike, black-site, or otherwise liquidate anyone who could be associated with Islamic extremism. Be liberal in doing so. Make children fear blue skies because of drones. When the orphaned young children grow up, do it all again. You can also throw a literal man-made famine in there if you want.

The final option is the Chinese option. Mass surveillance. Use AI to liberally target anyone who may be at risk of radicalisation for re-education. Teach them the lingua franca of China, Mandarin. Pump money into the region for development. When people finish their time in re-education, set them up with state jobs. Keep the surveillance up. Allow and even celebrate local religious customs, but make sure the leaders are on-side with the party...

Could China’s approach be done better? Almost certainly. Is it the most humane response to extremism we’ve seen so far? That’s for you to decide.
