Well for one thing, alot of asian males are small, wimpy and dorky. I'm the opposite. I'm tall built and no a dork!
It's a matter of perception really. ABC girls are sometimes raised in a more liberal fashion and therefore may tend to desire the white meat. Some do it for rebellious reasons. To get a rise out of their family. Others may just find them more attractive based on what they were brought up what attractive is (aka media).
Some guys again are just pushovers. Some guys will do anything to help out a girl who they like and that's the way alot of asian guys were brought up. To please the woman. But alas, the girls just don't get it. well maybe they do

I you let them walk all over you, of course they're not gonna want to be with you. Also it seems that since they would be pushovers, they wouldn't exactly be able to make decisions. Girls like it when a guy has control. Not all the time but when deciding where to go etc, the girl tends to want the guy to make the decision.
To sum it all up, alot of asian guys try too hard.
