The international relationship between the People's Republic of China and the United States of America is quite strong yet complex. Both countries have an extremely extensive economic partnership, and a great amount of trade between the two countries necessitates somewhat positive political relations, yet significant issues exist. It is a relationship of economic cooperation, hegemonic rivalry in the Pacific, and mutual suspicion over the other's intentions. Therefore, each nation has adopted a wary attitude regarding the other as a potential adversary whilst at the same time being an extremely strong economic partner. It has been described by world leaders and academics as the world's most important bilateral relationship of the 21st century.
