It is a fascinating place! I don't know as much as I'd like on the subject as I've only really just begun digging into it but I can make a couple recommendations as to reading material and the like, if you're interested! It is pretty difficult to get info on what is currently happening in the area but there's a decent amount of material available on the 50s to the 80s (and the pre-CCP era).
As to my dissertation, it is pretty embryonic at the moment but I'm comparing Indian and Chinese minority policies in the 50s and 60s, particularly in Xinjiang and Kashmir. They're both predominantly Muslim, exceptionally important to the idea of the Chinese and Indian nation-states, and basically represented the 'frontier' to both central governments. And I guess I'm just interested in comparing the two modern countries in general, as they're actually a bit more similar than people generally suspect.
