In March 2018, the US and China entered the stage of full-scale strategic competition, starting with the US Trump administration's trade war with China. This paper analyzes the U.S.-China competition, focusing on the conflict between China's One Belt, One Road strategy and the U.S. Indo-Pacific strategy. China presents the One Belt, One Road strategy as China's defensive strategy against US pressure on the Indo-Pacific strategy and as a productive national strategy to promote economic development in Eurasia. China also recognizes the U.S.-led Indo-Pacific strategy as a policy to adhere to the international order based on U.S.-led rules and to keep China in check. It also recognizes it as a Cold War and aggressive strategy to break away from China's characteristic socialism and weaken the leadership of the Chinese Communist Party. Currently, the U.S. is pressuring China with high-tech technology, a field of relative superiority that suppresses China. Currently, competition between Central America and the United States as G2 will have an important influence on the global political structure. In the face of a complex global governance environment in the future, the two countries must actively encourage traditional European developed countries such as Japan, Korea, Britain, France and Germany, and multilateral competencies such as India, Vietnam, Brazil, Russia, and South Africa to participate in international affairs to maintain a stable international order and structure. China and the U.S. should not focus solely on their own interests, but should expand the international structure by integrating the world's new and old forces of the world. We hope that the Central American strategic competition will develop the world structure in the G2+ direction.
