Pechenges, Avars and Bulgars all examples of migrations of Asian populations westward, and Mongols and Tatars of course. There are also theories about Finno-Ugric peoples that see them as originating in the Urals region, or even further east, so it could be possible to say that today's Finns and Estonians, Karelians, Udmurt, Mordovan, Mari peoples are descendents of migrations from Asia into Europe. But this area of Moscow called Kitaigorod, it does translate literally as 'Chinatown', but I don't think it has any relation to China. There are different theories about how the place got its name. Some interpretations say it just means a place outside the walls, and it was indeed the old merchant district just outside the walls. Some say it was because the Tartars lived there. As far as I know, Russian got its word for China, 'Kitai' from the Khitan, and I don't think the Chinese thought of the Khitan as being Chinese. So if Kitaigorod does have any relation to China, it is not to Han Chinese China, but to the peoples to the north, the ones who the Russians had contact with.
possibly the kitaigorod was named after the goods that the Turko-Mongol hordes traded there and not for the actual ethnicity of the people who were the traders.
Finno-Ugric speakers in Finland, Estonia, and Hungary likely originated around the Urals...so they could have been some mix of Mongoloid/Caucasoid from ancient times, maybe proto-Eurasians, before the "split" but today Fins are the most blond people in Europe, even more so than Swedes and although they are outliers the group with Europeans genetically...so the admixture was ancient.
My guess is some Finno-Ugric speakers (a minority) of warriors just conquered proto-Germanic/Slavic/Baltic type folks and made them speak their language, overtime they intermarried with the locals, changing the overall gene polls only slightly.
