Well not even Chinese Taipei believes they are not Chinese. That’s a purely westoid division. All Chinese and nearly all Taiwanese Chinese all believe they are all both Chinese.

I am curious as to how you determined that the UK's surveillance is more strict than China's though.

For starters, the UK has some of the most intense digital surveillance laws in the world, for example:

The snooper's charter

DRIP (although this one was repealed by EU courts, it's back on the table again post-BREXIT)

On top of that, UK laws around protests severely restrict what can he deemed a legal protest. And police can arrest you on suspicion of protesting in a "disruptive" way. During the king's coronation, six people were detained on suspicion that they might possibly strap themselves or their signs to something.

In the wake of those Just Stop Oil ones gluing themselves to stuff, glue was added to the list of items a police officer can "stop and search" for with no restrictions (take one guess at the sorts of people the cops like to target with this).

You're probably aware of the "spy cops" scandal, well a bill a coupla years back was put into place to prevent any legal recourse to people targeted by spy cops and gave protections to secret service types caught torturing people.

This isn't an exhaustive list, just a few examples.

Also, this should in no way be interpreted as a defence of China's surveillance state. Just that the UK is currently even worse about it.
