Haha, I'm a bit complicated. I'm half-Chinese, half-Japanese. Born in Hong Kong, have a Japanese passport. But all in all, I'm Asian.
I would never date any African, North Korean (for kicks), Indian, or mainland Chinese guy. Nor would I date a Filipino or Indonesian (not Chinese Indonesian, pure Indonesian) guy. If I ever marry and have children, I want them to have the easy life and not have to worry about their father's nationality, their skin color, etc. I don't want them to be looked down upon, to have to go through more security checks because of their skin color, race, etc. Plus, my parents will absolutely not allow me to date guys with those nationalities. (Too strict, you have to adhere to their culture/religion's rules, etc. There's a whole variety of reasons that make sense and aren't racist.)
I do find myself attracted to Japanese, South Korean, Canadian, "American", and "European" men. More than nationalities though, I think I prefer men that are taller than me and that have glasses or slightly curly hair. (All the men I've found attractive had at least one of those traits...)
