Admittedly I don’t know many because I haven’t lived there but from what I know white people that have moved to Africa or Asia they think of their children as from that country.
But they much more often marry locals. Asians tend to marry within their ethnicity or even their family and tend to think of themselves as that previous nationality.
How many white people are elected in Asian and African countries? They don’t seem as well received as the locals compared to the west.
