Yet anime and K-pop are extremely popular in China. Go speak to people in the metropolitan areas of China, ask them what they prefer in terms of media, products, and even governance. Chinese soft power is so powerful that Chinese don't support their own industries. My own aunt is a diehard iPhone fan despite being a party member. Chinese soft power can't even convince the vast majority of Chinese within the country. People still worship the ground white people walk on.
Yet Doraemon and Detective Conan movies, two of the biggest anime IPs in China, regularly pulls in between 10% to 20% of Boonie Bears movies at the box office. Heron and the Boy, Hayao Miyazaki's latest movie, currently has no release plan in China because no distributor in China thought enough people would watch it to justify acquiring the rights. Anime aesthetic is popular, anime itself much less so.
