He's just bluffing. As usual, he is giving out his "Anti-West" stance and went in over their head.
One thing about Western Media is that they are fragmented, and they never tow the country line, so you are bound to find a lot of different voice in Western Media, and some of those are going to be Pro-China. i have literally found 11 article talking about Xinjiang development in Western Media or Western based Media in a little less than an hour. On the other hand, I would hard press to imagine there are a Pro-West Chinese media out there, Mr Beijing here is fighting a lost battle, he just too stupid to realise it. That's why he refused to engage with me on this.
