You should understand what you're reading. The only example really is the annexation of Tibet in 1950, which was obviously controversial but it's also complicated because it ended the practice of slavery in Tibet. Yes, slavery.

Korea? China ended up getting involved to support the North Korean government so China (and the USSR) didn't have a US client state on their border.

Laos? This was bad because China supported the Khmer Rouge.

Vietnam? Military assistance to the North Vietnam government to resist a US imperialist invasion. Did China invade? No. Do they occupy it now? No.

The rest are basically just minor border disputes with Vietnam, Burma, India, etc. And China hasn't really been involved in any foreign military action since 1979, 47 years ago. I'll stack that up against the US in particular as well as the European colonial powers (even in modern times).
