My question aims to know what kind of procedures did the Chinese government (allegedly) take since 2014 in Xinjiang, and why to begin with. And what can we know about the region in the current time, like can a random tourist go and see with their own eyes the truth, and maybe film it ?

There are Youtube videos and a Wikipedia page "documenting" human rights infringements, while China and the Marxist forums deny anything harmful. Now that almost nobody is bringing it up, I want to know what was legitimately documented. Investigating the origins and later developments of the case on my own would be so hard.
