alt Hacker NewsJapan has been exporting its culture for decades with games(Mario/Zelda/Final Fantasy..the list goes on). And nowadays anime is also very popular.
China has nothing really, can't think of a single interesting Chinese game/movie/TV show. If you include Hong Kong a few appear, but that isn't really China, and output has died since China forcefully took over.
Maybe it is just me but I also find Chinese really annoying in the way that it sounds, very harsh and unpleasant, something about the tones gives me a mild headache.
Genshin Impact, and Black Myth Wukong are both extremely popular chinese video games with big penetration in the West, but this is extremely recent.
Hong Kong kung fu and crime dramas were pretty popular in the west in the 70s and 80s, but definitely a niche and nothing like Japanese Samurai films as far as popularity.
