Theres nothing inherantly more appealing about the asian "look" to white men, but nearly every man now days outwardly or secretly wants an asian girlfriend, why is this? Simple: Asian women are the only women left who...

a) aren't fat b) will look at non-chads as partners

White women in 2020 who actually take care of themselves and have a BMI less than 24.9 (or a bodyfat less than 26%) have nearly infinite SMV. When I go to the gym, I basically only see these women by themselves (aka they're on the carousal) or with a basically perfect specimen of a hunk boyfriend (an 8+/10 "Chad"). These women aren't 8's themselves, they are just normally 4's, 5's and 6's that happen to be skinny/slim/fit. As a 4, 5 or 6/10 male, You cannot touch these women, as social media/tv has hypergamized these women into the deepest depths from which their outlook on average-looking men in their league can never return.

Meanwhile, many Asian women have been sheltered, and thus are not only not fat (as they have been kept from high caloric western food and fed on usually healthy stir fry vegetable diets) but also are less effected by the great hypergamy boom of 2007-present. For sub 7/10 men looking for some amount of happiness (i.e. a non-fat girlfriend), this is their only option. This has resulted in the skyrocketing demand for Asian girls and the reason more and more men are picking them up, especially non-Chads.

Nothing lasts forever though.
