I saw the same behavior for foreign students studying in China, they only hangout with their own group due to language and culture barriers. My university has lots of foreign students but i have never meet any of them in social settings except one for like 10 minutes during my 4 years undergrad. Even within Chinese in China, people from the same region tend to hangout much more due to language and culture differences. I grew up speaking both mandarin and cantonese natively so i made friends with both sides and saw the same pattern. I would say this is just human nature. It is amplified for Chinese students in the west because there are more of them ;) Believe me, they really want to hangout with native students as well, but it’s not easy. It’s like you know going to gym is good for you, but because it requires extra hard work every day, you ended up skipping it.
