When it comes to the allies and actions leftist Uyghurs might want, it depends a lot on the social positions of the people involved. I agree with a lot of what the OP says, but agree with @NDLoubere that the co-construct of capitalism-colonialism must always be refused. https://twitter.com/Dave_Brophy/status/1286091142975467521

I also find the OPs view of left action problematic in its erasure of Uyghur voices. In the years of fieldwork I did in the Uyghur region I have not found evidence to support the OPs claim that Uyghurs overwhelmingly view themselves as East Turkistani & loath the Chinese state.

Very few saw opposing China and establishing the nation state of East Turkistan as an intentional objective or life goal. The vast majority of Uyghurs I’ve interviewed were, however, concerned with basic human and civil rights protections.

They want to remain the authors of their own personal and collective history, they want institutions that protect their interests and give their children a better future. Until 2017, nearly all of them saw potential for this to happen within the Chinese state.

By framing Uyghur sovereignty as the OP did – East Turkistan or nothing – an entire spectrum of self-determination is elided. And no space is left for Uyghurs who see autonomy differently.

Here is a non-exhaustive, fully-debatable, working list of the types of allies/actions my leftist Uyghur friends might want to see:

1. Instead of focusing energy on critiquing the right wing cooption of Uyghur internment and unfree labor as an anti-China talking point, leftists could focus their energy on showing the urgency of the situation and how it is linked to global capital and Islamophobia.

2. While educating themselves about Uyghur needs, leftists can assist Uyghurs in diaspora in documenting and translating the crisis of dispossession and domination that is produced through the reeducation system;

And help them publish their stories, preserve cultural traditions, apply for grants etc: building institutions that are funded autonomously and responsible to the Uyghur community *and* allies on the Left.

3. Leftist Uyghurs would like to see western corporations held legally & morally accountable for their complicity in Uyghur dispossession. Ultimately this would look like reparations that provide autonomous funding for Uyghur institution building. See here https://www.workersrights.org/communications-to-affiliates/new-wrc-report-hetian-taida-badger-sport-china/

4. The American right wing is certainly the wrong group to do this, but multi-billion dollar technology companies who automate racism/Islamophobia (whether it is Amazon or Sensetime) should be held accountable. Brands & producers who profit from Uyghur unfree labor should also.

5. This might start with labor-rights solidarity movements, but, ultimately, requires global legal instruments that target companies who expropriate the data & labor of minoritized people to reduce this colonial/racial violence.

6. Finally, all leftist Uyghurs I know, tell me that the urgency of the situation demands that democratic, antiracist governments and institutions require public supply chain transparency on goods and services in the Uyghur region (but would be good everywhere);

And, if clear evidence is established and made fully legible, apply multilateral targeted sanctions or penalties on companies which profit from crimes against humanity.

As my Uyghur friends have told me many times, regardless of whether or not such sanctions "work," they produce a moral cost and they tell Uyghurs that their suffering is real and their lives have value.
