Taiwan is a matter of perspective. From the Chinese perspective, there was a civil war and the KMT lost. That's also the official position of the US, the EU and most countries in the world. It's called the One China policy. And China seems happy to maintain the status quo and leave the situation unresolved. Is it really imperialism to say that ultimately there will be reunification?

Even if you accept Tibet as imperialist, which is debatable, it was in 1950. You want to compare that to US imperialism, particularly since WW2 [1]? And I say "debatable" here because Tibet had a system that is charitably called "serfdom" where 90% of people couldn't own land but they did have some rights. However, they were the property of their lords and could be gifted or traded, you know, like property. There's another word for that: slavery.

It is 100% factually accurate to say that the People's Republica of China is not imperialist.
