Abstract: With a solid foundation of cooperation and economic dependence, RCEP member countries have chosen to work together to cope with the global epidemic crisis and the trend of multilateral system sliding to low efficiency and disorder, realizing their own interests under the new framework of regional integration. The significance of RCEP lies not only in the economic aspect but also in the strategic aspect. RCEP has created a new opportunity for multi-faceted cooperation, which will profoundly change the economic and trade pattern in the Asia-Pacific region and even in the world. It will also provide great assistance for China's participation in global economic governance and the formation of a new international and domestic development pattern. It is necessary for China to seize the opportunity to further deepen the development of RCEP, consolidate and strengthen ties with other members and link RCEP and the Belt and Road strategy, in order to play the leading role and show the important influence in the reconstruction of the economic and trade pattern of the Asia-Pacific region.
