On the surface, the US seems to have a major upper hand in its trade war with China. Simply put, they export a lot more to the US than we do to China, which means that they have more to lose than we. However, looking closer at the imposition of the US’ attest tariffs, a significant weak spot emerges. That weak spot is that the US has become overly reliant on some very niche but important Chinese exports. Mot of these are things people have never heard of, like carbonate esters and fluorine salts, both used for electric car batteries. Nonetheless though, they are very important, and 297 such imports were recently exempted from the US tariffs.
FINSUM: Barite (for oil and gas exploration) and Ibuprofen, are other crucial imports. This is one of the pressure points where China could simply cutoff supply and the US would be in a difficult position.
