Not all Koreans are white.

Ethnically they are white and ethnically Vietnamese are.  The Koreans have that look of being European with ingrained a light tan, like the English.  They seem quieter though and more secluded.  I take it Korea is lower than Japan, which is dry for being surrounded by so much water.  Literally, Chinese are whiter in every way.  Maybe not so much worried about anything like the southwest because that gets into Vietnam and it's sexy.  Vietnamese have that look about them of being in an adventurous place, shaped more Chinese and even more attractive than some of the inland Chinese.
