I think people are misunderstanding Turkey's current moves. I wrote about Turkish FM visit to China and what he said in detail in another post
here.
I actually think Turkish FM visited Xinjiang and interacted with the locals precisely to assuage the exaggerated claims of some Turkish people who trust the western narrative.
But of course, he can't just totally dismiss and be silent of the concerns otherwise he'd be accused of selling to the Chinese (in fact Al Jazeera already ran a hit piece about this topic accusing him of silence). And it's important to see the comments in their full context:
I actually read it as him saying that there is no problem and what China really needs is a better PR team and his visit to Xinjiang is aimed at helping China achieve exactly that.
