Since the official signing of the RCEP in 2020, it has become the world's largest free trade agreement, and joining the RCEP has brought a new round of opportunities for China's economic and trade development. This paper describes the trade status and problems between China and RCEP-related partner countries, selects the data from 2001 to 2019 for empirical analysis, uses the GL index as an indicator to measure the trade level in the industry, explores the factors affecting the trade relations between China and its partners based on national characteristics, and makes suggestions for promoting the development of trade relations between China and its partners. The results of the study show that the level of economic development and whether to join RCEP are two factors that will have a major impact on the level of economic trade between the two sides. Actively promote the implementation of the RCEP agreement, strengthen the construction of economic level, and strive for new member countries to join the RCEP to promote the steady development of global economic and trade integration.
