I dont know, to me it looks like Trump caved to the pressure..if this was all about China he would have left everyone else alone..now the other countries wont bother negotiating because they think Trump wont go ahead with it
All you need to do is to look at a tariff table BEFORE this happened vs what these countries are willing to do now.
Tariffs now are NOT like tariffs in the 1920s. The goal was always China, it our biggest deficit partner and with Russia dying slowing in Ukraine, now our sole adversary. China does not exist without the US market.
They've already started negotiating.
