Answer:
he relationship between the two countries has been complex, and varied from positive to highly negative. After 1980 the economic ties grew rapidly. The relationship is of economic cooperation, hegemonic rivalry in the Pacific, and mutual suspicion over each other's intentions. Therefore, each nation has adopted a wary attitude regarding the other as a potential adversary but has meanwhile maintained an extremely strong economic partnership.[2] It has been described by world leaders and academics as the world's most important bilateral relationship of the 21st century.[3][4] The downside is that Americans see China as a threat to the established order in its drive for regional hegemony in East Asia now, and a future aspirant for global supremacy. Beijing rejects these notions, but continues its assertive policies and its quest for allies.[5]
