Vietnam is a NorthEast Asian country mainly due to its culture and history, Chinese confucius culture and a tributary vassel state of Imperial China for centries, together with a large size of ethnic Chinese community there.
However, Vietnamese by and large are NOT NorthEast Asians ethnicly, but SouthEast Asians, the same as Tais, Laos, Malays, etc.
Mongolians, a tiny population btw, are of the same race but it has a long tradition of being an uncultured nomad steppe historically. Inner Mogolians have largely absorbed by Han, while Outer Mongolians nowaday have significant blood mixing with Central Asians and Russians.
My "failed" logic?
Mind you that you just agreed that it DOES have everthing to do with my logic by saying "It is a country as a whole". Exactly so! Haven't Indu's average IQ told the whole story already?
?
no idea with what kind of logic and order u r talking and laughing about...
Go find a psychiatrist, will you?
