The thing China can do, and does do: Kill your network connections, whether that's a TCP session, your ability to send or receive packets with some particular IP addresses, or at the extreme armed men show up and now it's not an Internet problem.
Things China can't do: Magically "downgrade", "decrypt" or "intercept" the secure protocols we use every day like HTTPS. Facts won't budge, the technology we are using does what it says on the tin.
The Internet can't route around you being thrown off a tall building by men with guns, but the IETF has for some years considered it to be extremely important to design the network protocols to prevent these shenanigans. BCP # 188 "Pervasive Monitoring is An Attack"
