The key distinction here is between white men who meet Asian women during their travels, or work, or life situation in Asia, and white men who go to Asia in order to find a woman who they deem to be easier pickings than white women.
One can be potentially romantic and the basis for a real marriage. The other is essentially transactional sex tourism by desperate and unattractive men.
Going to Asia for a "good wife" still retains deep blue pill conditioning -- that a fairy tale ideal still exists, but it's only in 3rd world countries, not here.
That fairy tale ideal is founded on patriarchal, male-primary domestic relationships, which were once the unquestioned standard in the west -- basically, that men are entitled to devotion, sex, and service from women. You'll note that the definition of a "good woman" in many manosphere circles always includes "good cook, keeps a good house, treats her man like a king" etc.
The rise of feminism has robbed a significant portion of lower-SMV men of that entitlement. Hence, the rise of the toxic red pill ie. "western women are all slvts, they're all hypergamous garbage" etc. because women now retain the right to be selective and not conform to the traditional standards of domestic relationships -- and thus deny these men of their birth right.
So, bitter and disenfranchised, they go overseas to far and distant lands, in order to seek that birth right of a subservient, submissive, devoted wife who is always sexually available and doesn't question her place and her role in the domestic arrangement.
Only to find, of course, that globalization of western culture has already reached these far and distant lands, and women there aren't as willing to be a seen-and-not-heard housewife -- unless, there's something in it for them.
3rd world mail order brides divorce-raping their white husbands once they're here and clear to stay as permanent residents is now becoming a thing. I've heard it's especially common among eastern European women, who have broader appeal in western societies and ditch as soon as they get a better offer.
Unless, of course, your 3rd world mail order bride isn't going to get better offers. I see a lot of unattractive Asian women with unattractive white men, pushing strollers with kids who probably canceled out the ugly and will be interesting-looking. They look like happy families.
