Isnt this like a repeat of when UK invited Chinese representative to Queens funeral then later some of them threatened to ban him from the ceremony ? Like nobody knows who the feck actually runs that country"gLoBaL bR1Ta1n" be acting like an immature snob:
If the UK arrests the Xinjiang governor (who is an Uyghur himself), then China certainly can reciprocate in kind.
There are quite a few British diplomats in China, alongside so-called BBC "China correspondents". Any of them can be nabbed on charges of espionage and conducting operations that are harmful to China and the Chinese people.
China already has first-hand experience of dealing with US-Canada's unlawful joint-kidnapping of Meng Wanzhou. Sure, London can attempt Act 2, and let's see how that goes down for the UK.
