The problem is that the scope of trade war 1.0 was quite small compared to bilateral trade, which is not the case with trade war 2.0.Nope in the first round was absorbed by US consumers nearly exclusively. Hence why living costs went up so much in US while remaining unchanged in China.
China moved down Yuan much later, with the auto industry boom. It has nothing to do with the trade war, it was a move to gobble up auto market.
Tariffs affected inputs and capital goods, not consumer goods. The overwhelming majority of cases of protectionism are aimed at consumer goods. This was not the case in trade war 1.0. An incredible 95% of the tariffs applied were on capital goods and intermediate goods. These are the materials that American companies and industries use to manufacture products. These companies and industries paid more, which led to an artificial increase in their production costs (which is why small and medium-sized companies were being negatively affected).
