Okay, I assume you genuinely care about the people of Xinjiang, so don't you think it's worth to try and know those things?
I'm not trying to attack you personally, but have do you have a rough idea of what the solution to this region's problem should be?
Because I really really doubt the west is gonna support a creation of another Muslim country in central Asia.
And this is not some abstract shit, because these stories are used to justify specific policies that the US takes in regard of China, but said polices never ever seem to be related to Xinjiang and are instead just broad attempts to hurt China economically. And again, there is a very simple move that the US and the EU can do tomorrow to support the Xinjiang independent movement, and it's so off people radar that most don't even know that this is something that might make sense to ask their own government to do.
China official foreign policy ethos is the Five Principles of Peaceful Coexistence, which generally can be summed up as "don't start nothing, ain't gonna be nothing" (and in less dumb joke terms, it means that China at least officially believe that whatever happen inside a country's borders is their own fucking business).
Now obviously, no country ever live up to their ideals perfectly, but generally speaking, unlike the IMF, China don't force structural changes to a country's economy as a condition to get loans.
