Perhaps you should prepare a placard to protest in front of the Chinese Embassy.
OTT:
Funnily enough, I happened to pass by in front of the Chinese Embassy, when I used to go to the Riba for CPD sessions.
So, just before the embassy entrance you can see a couple of policemen of the Met and on the other side of the street, just before the Riba entrance, 24 hrs a day stands a Chinese protester from some kind of cult (according to the Chinese authorities): the Falun Gong.
