Trump's reversal after the Sino-US Head of summit meeting in Osaka undermined the win-winrelationship between China and the United States in economic and trade symbiosis. The frictional confrontationbetween the US and China in imposing tariffs and countervailing tariffs aggravates the risk out of control.Instead of alleviating the frictional tension between the US and China, China's path-dependent counteractingtariffs have intensified the escalation of confrontation. The imbalanced trade volume and product structurebetween the US and China determine that China and the US are in an asymmetric frictional status. China'scountervailing tariffs have fallen into the trap of Trump's spiral tariff imposition. There are four differentsituations in which tariffs imposed by both the US and China may not necessarily hurt another. China need takethe promotion of the return of the US to economic and trade consultations as its main point and oppose the useof zero-sum thinking to undermine the win-win economic and trade relations between China and the US. Thestandpoint to deal with the escalation of Sino-US economic and trade frictions is to promote a new pattern ofcomprehensive opening-up, to resolve economic and trade frictions through consultation and cooperation ratherthan confrontation, and to develop China's economy and smooth employment. The measures are as follows: breaking the passive way of dealing with frictions, improving the standard of business environment, promotingthe motive force of institutional innovation of the free trade pilot zone, building a world-class businessenvironment through continuous import expositions, promoting the docking of Chinese manufactures withglobal production, enhancing the cohesion of China's economy, and maintaining a good linkage with the globalvalue chain.
