Given up already? Even before you got started?
Anyway, I've chanced upon a book that will be of interest to anyone considering Asian chicks.

It is very well written (you might find a PDF version on The Pirate Bay).
Anyway, it provides a lot of details about cultural differences for Thai female/American male couples. I'm sure that a lot of it would be relevant if you were considering other Asian cultures, too.
Perhaps the most important thing to understand, before getting started: typically, the top priority in life, for a Thai woman, is to provide the highest possible standard of living for her parents. This might lead to some misunderstandings with an American husband, who doesn't want to see a huge chunk of his wealth and income being transferred to inlaws in Thailand.
In America, we prize independence and self-reliance. In Thailand, it is the opposite.
It can be difficult for first-generation Thais in America, who work hard to support their parents and family members back home. Their children, on the other hand, grow up with American values, and don't want to support their parents once they've grown up. So, rather than stuffing their money into retirement accounts, they've been supporting their parents, and end up not being supported in old age by their own children. The standard American practice is to send the elderly off to die in nursing homes. Which is something that just wouldn't happen in Thailand.
