The thesis here bespeaks of the very arrogance we have regarding "dealing" with China. China is a major world power. Its existence and growing economic prowess are not dependent upon our acceptance, investment or "good will".
We continue to deal with China in an extremely condescending manner. To "deal" with China means we have to accept China for what it is; including that its political system is different from ours. It is not going to bend to our system of liberty and individual civil rights because we think that's the natural order of things. And in all frankness, our current political morass is hardly a paragon of virtue to which other should strive.
We can choose to ignore China and attempt to isolate it. But that didn't work out so well when we tried it after 1949 did it?
All these tariffs are accomplishing is incentivizing Chinese corporations to rapidly expand their production capabilities in facilities located in other nations. So in fact, we are financing China's increasing power and influence over both its neighbors and within the global economy.
We're now at a point where China doesn't "need" us. So we simply have to decide whether we want to interrelate with another major world power as it is or move towards confrontation and chaos.
