At some point after 2008, I want to say around 2010 or 2012, Hollywood started putting China in their movies more. The ones that stick out to me are Transformers (the first one with Wahlberg), The Martian, Avengers 2, Looper. There are more.
I know Disney tried really hard with Mulan but failed. There was that big Chinese-produced movie with Matt Damon, no idea how well that did.
When do you think this thing will stop and go the other way? At some point Hollywood libs are going to fall in line. When will they give up on China as a market and make money off not only ignoring their market but also insulting their market? I can see a big return of the 80s action movie aesthetic with Chinese bad guys and advanced foreign invaders.
I think you may see more mainstream movies that are critical of China, but I doubt you will see it major franchise movies. It will likely be the artsy movies that are also intended to make some money.
As long as China exists as a market (I do not see why it would cease to be), I do not think it will be ignored and it will be pandered to, be it involvement from local performers or industry creators or co-production with local studios.
Something else to remember is that, even if a movie is released by a United States studio with a largely American-based cast and crew, there may be Chinese investment. This could be Chinese studios being involved in the production or Chinese-based individuals, organizations or even their government having a stake in the studio proper.
For example, China Film, owned by the government, has had involvement in the following movies: Furious 7, Pixels, Warcraft, The Great Wall and The Fate of the Furious. Each of these were released by Universal, with the exception of Pixels, which was released by Sony. There is also Alibaba Pictures, owned by Alibaba Group. They have had involvement in Mission: Impossible - Rogue Nation, Teenage Mutant Ninja Turtles: Out of the Shadows, Star Trek Beyond and Mission: Impossible - Fallout, all of which were released by Paramount. Additionally, Alibaba is a partner in Amblin Partners, the owner of Amblin and DreamWorks (not to be confused with DreamWorks Animation).
