Given his Twitter feed looks like a Chinese diplomat's[1], I would assume he is part of the pro-Beijing influence network. I mean, why would someone dedicate 6 months of their life to convincing the world that something isn't happening which is reported on widely (even by some limited Chinese media)?

I have no idea if he is scheming with the the government or if he is simply trying to curry favour, but if you are a gwai lo (westerner) in China and want to get ahead for any reason (visas, job whatever), this is precisely what you would do. Whether its voluntary propaganda or paid propaganda, it's still propaganda.

edit: This is the kind of blatant propaganda I'm talking about: https://twitter.com/Jerry_grey2002/status/129826250774052044...
