Seems like self-identification answers these questions.

Nation-building is a fairly new concept.

This belief is really niche, globally- and reacting like it’s a morally correct perspective is weirdly a form of cultural imperialism.

I am talking from a purely political perspective, and since China has a one party system with only one broad political ideology allowed, I thought it would be obvious that I meant the political leaders of the Communist Party of China. (I cannot be more specific than that because I don't know the spectrum of political thoughts that is allowed within that ideology in the CPC).
