Apparently Trump lied about that call. Chinese never called.
China isn't a democracy and can/will wait it out until next prez. They don't care because they know their growth will continues at modest 3-6% while the western worlds will fall into recessions without Chinese consumers.
I tends to agree with China. There is no point negotiating with Trump. And when US get back to the bargaining table, they will be in weaken position. As much as I hate TPP, it would have kept China in check. As much as we want to make stuff in NA, you just can't compete with dictatorship that promotes 6 12s as normal work week. This is why Telus/Bell prefer Huawei gears, it's cheaper, better and problems resolutions can be had in days instead of weeks with Ericsson.
