China's economy is very export dependent. If Chinese businesses cannot use internet to access a lot of U.S. allies, it would suffer badly.

For example if, say, all U.K's companies are not allowed to use email or skype to talk to the Chinese, or all U.S., Canada and Australia, etc. web sites are not accessible from China because of some executive orders or laws by the U.S. (similar to google complying with the order currently), then I guess China's economy would be severely affected.
