THIS eventful summer would be remembered in history as a watershed for China-U.S.relations,right on the start of the 100-day countdown for the American presidential election.The U.S.senate first blatantly butted in on China’s internal affairs by passing the so-called Hong Kong Autonomy Act,and then its Secretary of State issued a statement,denying China’s lawful territorial and maritime claim in the South China Sea.This soon culminated in the out-ofthe-blue decision by the U.S.government to close China’s general consulate in Houston,which was responded to by China in kind to close the U.S.general consulate in Chengdu.Then came the speech made by the U.S.Secretary of State Mike Pompeo at the Richard Nixon Presidential Library on July 23,declaring that the bilateral relations should be based on the principles of“distrust and verify,”and negating the U.S.former engagement policy to China,which made people truly feel the chill of the relationship between the two major powers of the world.
