They're already behind a great firewall, so they should have no problem using NAT with their citizens for easier restricting of freedoms, and for the actual services they need to run, they can assign a limited amount of static IP addresses for servers, and the rest NAT as well, and port forward for specific services.

Probably not the biggest flaw in this plan, but:

Total number of RFC-1918 addresses: 18+ million.
Population of China: More than 1.325 billion.

I'll leave the other political aspects to others, but, the math simply doesn't work.
