The ethnic cleansing Uyghur concentration camps are probably the biggest one. Also threatening Taiwan, which is a lovely country I would hate to see destroyed. Besides that the social control the government exerts is pretty frightening to me (I've lived in China).
All that said I still see China as less of a direct threat right now.
Some good points, I was aware of them, but comparing to the current US it doesn't seem as bad.
I just don't know how bad the Uyghur was/is considering the propaganda that both sides would push, with China not letting independant investigators or reporters do anything in and the whole US manufacturing consent media and US government propaganda. Then them calling it a genocide while Palestine is not.
You do realize that most of this is US propaganda, right? Xinjiang is like a fully developed economy and Uyghurs are doing well. I visited Beijing last summer and asked some Uyghur workers who discussed their conditions openly.
The re-education camps were for a small part of the Uyghur populace that were involved in terrorism against other Uyghurs and Chinese.
All that said I still see China as less of a direct threat right now.
