There are a number of posters here who see this as simply a negotiating tactic by the Chinese, tough talk and then they will back down. I suppose then that they all also feel the same way about Trump. The talk about NAFTA was just talk, the softwood lumber concerns just talk, the border tax just talk. Let's see what happens with the States, before we assume that the Chinese  are just blowing smoke. When you go out of your way to tell the world how much you want to trade as the PM did, you are not necessarily starting from a position of strength.
