They'd welcome them to the extent of weakening their defenses, creating a rift between natives and the foreigners then taking control either under the premise of 'preserving asian culture' only to exert their own more or militarily if defenses get that weakened.

There's a difference between being surrounded by 'inferior asians' and having to deal with the likes of Africans or Muslims on your doorstep, just ask the Uighers.
