Define "East Asian only group". Do you mean a division that's only East Asian? Or a social group within the company that is exclusively for East Asians? And how would that come about organically? East Asians aren't really homogeneous, there is a lot of ethnic strife between the different East Asian groups (HK vs Mainland, Mainland vs South Korea vs Japan). So I can't really see how they'd naturally be a closed off clique.
