Which countries in Eastern Europe have more of the following non-white groups?

Romania has native Tatars that look Mongolic and native Roma that look Indian, even South Indian. also a pretty large Arab community of students in the main cities. Black French students are also a common sight in the main cities, due to universities

The Vietnamese born in here speak just like Czechs and their knowledge of Vietnamese is very limited. Of course there are also recent immigrants from Vietnam and they usually can hold a conversation quite well, but they sound kinda awkward and have a strong accent. Pretty much the same goes for the Chinese, who are almost always recent. As for Indians, some of them speak some Czech, but those who are employed in international companies will usually only speak English. Never heard an Indian speaking fluent Czech.

How many actual Indians do you have though? And which countries do the Arabs mostly come from?

Roma are ethnically actual Indians, a subgroup, as WASP are actual NW Euros, only more mixed (mostly as Persian/Ottoman heritage, but also local Balkan nowadays).

Arab students come from Israel mostly, and a bit from all the Arab countries for the rest

Not that much - close to 10k. But it already qualifies as a fairly large non-white group given our standards. Of course they tend to concetrate in the larger cities, so while they are a common sight to me, someone from the mountainous borders of Czechia had likely never seen an Indian before.

Arabs, blacks and the like are pretty much nonexistent in here. I know one North African family from Algeria and I remember some Syrian guy from the elementary school, but that's about it.

How common are Czech-Asian marriages?

Extremely uncommon. I'm not the youngest fellow around here and I've seen maybe just two or three couples like that throughout my life. One of them being a Czech immigrant to Canada who married a Thai woman whom he met on his 'holiday'. Not sure if that counts. Anyhow, those Asians in here tend to stick to their own.
