Likewise you haven't disproven my thesis that China is not closed to immigrants.

A good friend of mine (white European) was approached by a Chinese company and now works in China. I'll ask him how hard the paperwork was the next time I meet him, but I have a feeling his employer did the bulk of it.

That's fine, since nobody attempted to disprove that in the first place.

The idea that they're at a disadvantage to Ireland in that aspect because the latter has more numbers-wise was what was addressed.

They might very well not be open. Or they might be open in a selective and cautious way, which would be more prudent than merely being open for all.
