I live in China and this software is cancerous not just in the encryption failure, it also nestles into a computer like a trojan. Creates 2 fallback installations and will reinstall itself after removal if you reboot in between, unless you get rid of all 3 installations at once, where they are deliberately trying to obfuscate the uninstall button (triple confirmation, swapping the confirm/cancel buttons and button background colors, etc.).

It’s a nasty piece of crap that come preloaded on any phone (android, at least) and Windows-PC here.

Be careful jumping the firewall.
Sure. Foreigners aren’t really sanctioned though, that’s more of a risk for the locals. But even then usually only if they want to get someone disappeared and don’t have anything substantial against them.
