China will be a multi-billion dollor market if Disney can get its foot into the mainland with the construction of Shanghai Disneyland.
More money made in China allows for more money to be spent on other Disney projects such as the US parks.
If past result is any indication, I'd say a successful park will just mean cuts to suck MORE money out of the park to put into other things. Afterall, that's what happens with WDW
