What is surprising, is just how worried about the prospect of widespread social unrest Beijing was: even after the demonstrations were effectively snuffed out, hundreds of security personnel patrolled around CBIRC’s office, "highlighting authorities’ sensitivity to any form of social instability" according to Reuters.
As I've said, Communist China is a far more brittle country and society that we in the West imagine. More economic hardship is on the way unless the leadership in China cuts a deal with Trump to defuse the trade war. Trump has all the leverage, he's more than willing to use it, and it really is just a question of when the Communists give him what he wants. Or, he'll get it when the illegitimate Communist government collapses in a fashion similar to what happened to the USSR once Reagan pushed them over their limit.
