That's exactly why we don't see the same level of kinship among Asians. Within their own racial subgroups, they understand that there's not necessarily an automatic alliance simply because they come from the same continent. That's like comparing Eastern Europeans (whoops, I meant Hungarians. I hadn't eaten yet, dinner was ready and I rushed through my comment to start eating) to wanting to ally with Romanians, simply because they share a space. There's bad blood there.
