By my understanding, TWDC and the Shanghai Shendi Group— a group comprised of three Chinese divisions each controlled by the Chinese government—hold ownership. TWDC owns and manages 43% of the Theme parks and 70% of the outside resort. That’s why this theme park is very unlike the others, where truly American symbols and themes, like Main Street, are omitted and 80% of the rides are unique to this park. Disney had to appease the government to make sure there was no American undertones and things were very chinese nationalistic.
So, with this in mind, wouldn’t Disney have to sell their stake of the park to get out of it? China can’t completely control what they don’t own in entirety. They can be a road block in determining what goes in the park and what doesn’t, but by my understanding, they can’t just take it over.
