Answer:

Japanese people are more open when it comes to different races and exotic people. They considered very pretty and or unique. There are allot of artists in Thailand the same way, except there's more Thai/with European descent. Gam the Star is the only one I know that is Thai/black. ...I always thought Thelma is hot btw -///- I wish there will be more Koreans this way too, slowly but surely.
