The very first obvious reason is Asian men. Most of Asian girls who end up dating a western guy, they get sick of the dirty end in relationships with Asian guys. This happens in many Asian countries; women wondering if her man will be able to support her and her family, wondering if her man will have a mistress, or wondering if she will be able to divorce him or she will have to stay with him if thing does not work out.
Western men are a lot more desirable for a life companion than Asian men. Western men tend to be a lot more loving and modern than Asian men. What Asian girls look forward to from that? Mostly freedom and more equality in relationship. It’s not that they want to take advantages on you, it is their nature to give as much love they can and they want that back from you too. This means that the relationship will be stable because it has the foundation of love.
Asian ladies want a mature. It is just so frustrating for them to feel like having a baby in a relationship. Asian guys are sometimes very unsettled in a relationship. That is just so disappointing and also the beginning of unfaithfulness. And for Asian women, white men are perceived as grownups. Western guys seem to be very settled and they always know what they want in life.
White men are also open-minded than Asian guys. Western people do not judge others based on where they come from, their family, cultural background, or social status.
And with a western man by their side, they will be sure of being told all the truth as they are. This means that there will be no secret between her and her partner. Asian guys always say things that girls want to hear, even though those are all lies. Unlike white guys that always tell the truth. So when a white guy tells a girl he loves her, he really means it.
If you are a white guys and you have all these characteristics above, then you are definitely attractive to Asian girls.
