Care to elaborate how China has banned it? Last time i was there I had no problem using VPN, and a dozen or so services that utilise encryption, PGP didn't magically stop working the moment i touched down. Customs were far more concerned about my camera batteries than tools of digital freedom on my laptop.
Seems like you are conflating the efforts of the Great Firewall with the word encryption here.
