This is even more of an issue than people may realize. This is Communist China imposing the restriction of free speech on a western country and violently. The UK should not put up with this authoritarian crap. An embassy is a privilege, and is there for goodwill and trust. Not to drag in your own citizens and assault them for freely protesting. They aren’t diplomats, they are oppressors. Declare them all persona non grata and kick the freaking door down.

Also fuck you Xi, you insecure piece of crap.
