I say this because having a different version of the movie for the Chinese market already happened with Iron Man 3. The doctor who removes Tony Stark's magnet was apparently played by a famous Chinese actor, and his scenes were longer in the "Chinese cut". It added nothing to the plot, the scenes were awkward and not very good. It was all obviously put in to please Chinese viewers.

You could say that making Poe/Finn canon for the world minus China would just be fanservice, but the very existence of a new trilogy after VI IS fanservice.

Best case scenario would be to say "fuck you China" and have them smooching for the whole world. Except Disney needs its precious yuans, so I'll take whatever I can get.
