Also, one cannot pin any specific attributes like nice, bad, good, subtle, direct, blunt etc. adjectives to an entire group, especially when it is a 1.2 billion group. There will be some similarities in certain aspects in a specific region because I suspect it would be case of trying to "fit" in where we stay.
agreed broadly, but there are generalizations that hold. they're always fluid, i agree, and malleable over time, but they change slowly, not quickly. (urbanization is a big part of that fluidity because urbanization is solvent for a lot of strongly-held views.) in this specific case, the insularity of Chinese expat communities has been a thing for many years, and sometimes, as in SE Asia, it's even caused political problems and violence.
caveat: speculation follows.
a lot of this, IMO, has had to do with who formed those expat communities. for a long time it has been small business people, traders, and agriculture guys - farmers, etc. it's not university-educated people who've been exposed to a diverse range of communities and ideas. it's people, for example, who had literally never seen a black person and never thought about them, and they often brought with them the same basic assumptions they had at home. like everywhere, this includes things like "my culture/ethnicity/approach is the best etc." that led to them not wanting, at an emotional level, to integrate wherever they found themselves. exposure to others, wider extension of education, and urbanization tend to make that stuff go away.
i need to point out, here, that i'm
describing things, not passing judgement on them. in my experience, most human communities are casually racist and have a superiority bias towards their own group. that's pretty normal.
Also, your "nice" experience could be a result of "you" belonging to a specific Y group.
nope. at one point, someone was explaining it to me, that was i better than many but still a notch or two down on the ladder.
And it doesn't mean they will be nasty to a Z group. Every group has their preferred types and it is complicated as we are humans.
i never said that. i also think things are more complex than people try to make them out to be.
edit: what that means, to bring it around to the original point about "the Chinese" being "blatant" about their increasing investment and presence, is simply that i don't think that's a thought-through policy thing. it's just a consequence of a chain of events that the people doing it took to be normal and never thought locals would notice. i see that a lot. most of history is contingent.
also edited for clarity.
