Americans "loving" kpop and anime is the modern form of orientalism. It won't stop them from a lobbying for a Chinese (Data) Exclusion Act.
Americans love Asian cars. Tons of Hondas, Toyotas, Hyundais, Kias, etc. Also while some weeby anime fans may be orientalist, not all are, and love for Gangnam style was genuine. It was a great song and people loved it for that, not because traded on Asian stereotypes. The American geopolitical strategy in the Pacific rests heavily on a very deep trust of Japan, Korea, and Taiwan, among other partners.
