Uyghurs, Tibet, and Taiwan, for starters. Taiwan in particular could become a conflict if push came to shove. Hard to say. (No nation will go to bat for the Uyghurs or Tibet, though.)
It doesn't change the fact, that as an European I really wish we had a better relationship with China and ditched US and their backward policies. It's OK to point out atrocities made by big empires, they are all guilty anyway.
