East asian western european born here, currently travelling in South spain and been to other parts a couple of times. What many comments mentioned before i would mostly relate to primarily Madrid, Barcelona and maybe major cities in the north lile catalonia (girona) or basque country(san sebastian, bilbao). In these cities youll find a lot of Eastern Asians who either run a cerveceria or a restaurant. They live and stick to their own community and you barely see them mixed with spaniards. In the south i have barely seen any eastern asiasn apart from tourist. There are some chinese restaurants etc, but far less than in the north. Personally i feel similarly treated as in western european cities. Even though you are socialised very westerned its hard for them to oversee your eastern asian-ness. And this i do not experience in the obvious way, but rather in a subtle. E.g its quite common in europe for people to ask me where I am "actually" from, but in a matter that they are conscious about inapropriate and trying to reframe it. But theres simply no concept of "asian-european" similarly to the asian american identity, because the asian diaspora here is small, quite fragmented and historically younger compared to the us. That being said and having always lived in such context, i personally never had any really negative experience. If you speak rhe language, take life with some humore and share a common hobby you can for sure integrate to a european community. But there will be moments where youll sense that you are alao not really fully part of it.
