asiophile
An Asiophile is a person who is fond of Asian culture, society, history or food. In a sexual context, it is a non-Asian person who exoticises or prefers Asians (typically East Asians). In other words, an Asiophile has yellow fever.
A white guy once messaged me on Grindr, and the first thing he said, "I like you. I only like Asians." Ugh. Total Asiophile!
