It's funny how Japan, after being awash in American culture for decades following WWII, more than made up for it with manga and anime, which all but pushed out old-school comic art both here (the US) and in Europe. When I meet young comic art fans and/or wannabe pros, they all draw in one manga style or another. When even the Disney product is anime-influenced, you know the seas have changed.
China already has a major impact on Western movies. The Chinese market is huge, and everyone here in Tinseltown begs major funding from China. In return the Americans have to follow a strict rulebook: no Chinese villains, no sympathy for Hong Kong or Taiwan, tacit recognition of Chinese ownership of the South China Sea, no Burma, no Uighurs, and above all no jokes about Beijing. If China doesn't like what you do, they pull your funding and you lose millions of dollars. It's all about the millions of dollars.
It's likely Andrew is right: this is shaping up to be the Chinese Century, not because of any structural superiority but because they're willing to do what the US did after WWII: spend endless amounts of money around the world to buy influence (and often hegemony) in less prosperous areas. The US could be doing the same thing, but the power elite these days is focused upon filling their own coffers, not retaining, much less expanding, national prestige. It's all about individuals getting as much as possible right now while giving as little as possible. The future ends at the next quarterly earnings report. The Chinese are playing the long game. Someday it will dawn on future American leaders that they've been relegated to the "B" league, and they'll have no one to blame but themselves.
