The shift of the global center of political and economic power from the Atlantic to the Pacific is a significant trend in the international landscape of the 21st century.The restructu-ring of the China-U.S.relations and the reshaping of the Asia-Pacific order are of crucial importance for the future configuration of the international order.From a long-term global historical perspective,the Asia-Pacific order began to take shape in the mid-19th century.After being released from the"overlay"of European colonialism,it has continuously evolved under the leadership of countries in the Pacific Rim region.Several wars from the mid-19th century to the mid-20th century shaped the structure of the Asia-Pacific order,which evolved from multipolarity to unstable bipolarity,and then to unipolarity,with the Asia-Pacific order taking on a distinctly autonomous character and becoming the center of the global internation-al order.The development of the Asia-Pacific order is characterized by geopolitical and geo-economic divisions and collisions.In the 20th century,the United States and Japan twice formed a bipolarity in the Asia-Pacific region,and their competition shaped the geopolitical and geo-economic framework of the Asia-Pacific order.The rise and rejuvenation of China is a major event in the Asia-Pacific geopolitical and economic space and is also part of the com-plex and synergetic development process of the Asia-Pacific order.
