This paper "Ignoring the Great Firewall of China" is a few years old, but at the time China was inspecting TCP packets for verboten keywords: http://www.cl.cam.ac.uk/~rnc1/ignoring.pdf The blocking was easy to circumvent. The researchers were able to just ignore TCP reset packets and the connections proceeded unhindered. They also were able to conduct a denial of service attack against IP addresses in China by spoofing packets with forbidden content, which would trigger spurious connection resets. This was 6 years ago, so I'm sure the game has changed somewhat.
