Is there any non-Borderline ASB way for an East Asian plurality (at least 25% of population) in a European state in Europe (can be as small as Monaco, as large as Russia)
Geographical definitions of Europe are present day. East Asians = Chinese, Korean, Japanese.
Bonus points if East Asian majority (>51% of population) is achieved, though I find that borderline-ASB.
With a POD no earlier than 1000 AD, how could this happen?
