One could say that this is merely the continuation of chauvinistic anglocentrism by other means, but to do so would embarass self-professed "anti-racists", hence white supermacy gets a new lease on life deep within the liberal mindset that nominally opposes it.
Tell that to anyone actually living in Asia and most will absolutely scoff at you. There is too much historical baggage about what horrifying things the Japanese did to other Asians during its colonial era (early to mid 20th century), especially with regards to Korea and China.

The "West" has had the longest record of invading other nations, forcibly "opening ports", or just generally intruding into and screwing up countries in other ways besides war.

Ever since antiquated Orientalism, it's rarely been an honest curiosity but more of a high-nosed "what's wrong with them" or seen as an exotic escape from the West's own mundanity.
The latter of course often ends in disillusionment, prompting generalized complaints about the object of fetish (if you lurk on any expat forums you may know what I'm talking about).
