I know Hong Kong differs from China mainland.. but American (all foreign maybe?) companies have to be involved with China somehow.
Not positive about the facts but for example...
GM couldnt just go to Shanghai and setup shop. A new company that originated out of China (SAIC) had to startup and become a joint venture with GM for operations to begin. It was the same way for all of the auto companies.
I may be wrong but I believe its a requirement for them to form the venture with domestic firms so they can enter the market. (So China could benefit from the increased control maybe?)
I would assume Disney had to reach this same agreement.. althought now that I think about it, theres about a million McDonalds, KFC's and Pizza Huts in China but they dont have any different branding on them. Who knows, maybe Im just hear to confuse you (intrigue you perhaps?)
Do your research, I sure didnt lol
