In response to Re: toe the line (heretosay (aka China Apologist))

How about the US?

I'd have thought that a foreigner employed there legally who has bought an apartment, and who has a US wife can get US nationality automatically after a fixed period of residential and uninterrupted time in the country provided he has a clean criminal record. In the UK, that period is 2 years.

That is a very different situation from China, where there must be very very few foreign teachers who can get Chinese nationality easily!

So, I'd say western countries are truly immigration countries, unlike China! China cherrypicks to a great extent - no comparison.
