China: for Taiwan, they are in the planning phase. (Vietnam, Hong Kong, Tibet, Aksai Chin, Korea, Scarborough Shoal do not count in your view of course). Not saying they are worse than the US.

What China did to the Han Chinese makes them worse than ANY other modern country. The great leap forward and the cultural revolution have not comparison. Add in the chinese invasion of Tibet in 1959 and 1979 invasion of Vietnam and they are butchers and imperialists.
