What I’ve noticed is there wat more of a Chinese identity than there is for other countries. Usually if a white person moves to another country and has children the children grow up identifying with that country.
But go to China Town anywhere in the world and it really does look like China, the newspapers are all Chinese newspapers for example (not that nationality in Chinese actual Chinese).
White people used to have an identity that held. Like Britisher for example. But I doubt any Aussies would say they are a Britisher.
The only exception is Americans than are actually American and 99% German but have 1% Irish so they tell everyone are Irish (but they actually know nothing about Ireland).
