I'm currently in China on a vacation. A few days ago, I was watching TV in my hotel room and CNN was broadcasting Trump's UN speech live. I tuned in as he was talking about China and the trade war. Everything was normal until he said "we're closely monitoring the situation in Hong Kong." Right after he finished that sentence, the channel cut to black for few minutes and came back when he moved on to Iran.
Also, fun fact, HN is blocked here.
