Let's consider the chinese internet access an 'untrusted network'. Let's consider your internet access at home a 'trusted network'.

Maybe you can set up a vpn tunnel out of the untrusted network to the trusted network and then route all internet traffic through the tunnel. That way they couldn't observer your internet traffic.

There might be other problems, though. It might be illegal to a) export encryption to China b) use encryption in China.
