Not long ago, the Regional Comprehensive Economic Partnership (RCEP) celebrated its one-year anniversary of full entry into force. As an important system for promoting the development of economic cooperation in the Asia Pacific region, RCEP has effectively improved the level of economic and trade cooperation within the region and provided important testing scenarios for countries to align with high standard international economic and trade rules. Globalization is the trend, and the concept of economic and trade cooperation has also deeply rooted in people's hearts. Regional economies should cooperate within the framework of agreements, promote high standard economic and trade rules, and further unleash dividends, which is also in line with the original intention and goals of RCEP. Making full use of various rules within this framework is an important measure to achieve multilateral win-win in the field of economy and trade. The positive role of RCEP in regional economic and trade cooperation is reflected in two important aspects: stimulating vitality and demonstrating drive. From the perspective of stimulating vitality, the significance of high standard economic and trade rules lies in achieving free flow of factors within the region and improving factor efficiency, which is consistent with the connotation of traditional comparative advantage theory. The economies in the Asia Pacific region have different focuses and advantages in the industrial field, with strong complementarity. The transportation radius they are in is also easily matched with industrial development. By connecting with high standard economic and trade rules, they can effectively achieve factor complementarity and provide important impetus for their respective high-quality economic development. From the perspective of demonstration and driving, the process of coordinating rules among numerous economies has provided an important demonstration for achieving fair and free trade through negotiation and negotiation internationally, and building a high-level platform for opening up to the outside world. It has also played a good driving effect on regional economic and trade cooperation. In terms of cross-border investment, trade in goods, and trade in services, innovation in each field can provide greater convenience for bilateral and multilateral trade, thereby enhancing the level and level of economic and trade cooperation. To move towards a better level of regional cooperation under the RCEP framework, it is necessary to further streamline the relationships in three aspects. The relationship between "inside" and "outside". In the process of aligning with international economic and trade rules and standards, actively and prudently handling the relationship between internal rules and external rules is related to the stability and sustainability of economic and trade cooperation within the framework. From the perspective of the industrial chain, the driving force of regional cooperation is the compatibility of regulatory rules. From the perspective of domestic supporting mechanism construction, integrating the construction of a unified national market with the integration of high standard economic and trade rules can help further break down internal barriers and form a demonstration. The relationship between short-term and long-term. Realizing the free flow of factors is a long-term goal, and it is important to avoid short-term and fragmented long-term goals. In the short term, we will focus on making necessary institutional preparations for docking with economic and trade rules, accumulate over time, and provide convenient conditions for promoting the better play of rules, based on the current situation and with a long-term perspective. The relationship between cooperation and competition. Regional economic and trade cooperation inevitably generates competition, and benign competition is also reasonable. When dealing with the relationship between cooperation and competition, it is necessary to rely on multilateral parties to jointly maintain the economic and trade environment, consciously resist the "anti globalization" thinking, think more about measures that are conducive to win-win cooperation, and achieve effective "competition and cooperation". From the specific practice of promoting high-level opening-up construction in China, making good use of RCEP related rules and providing more application scenarios for the rules to play a role are also important paths for cultivating new momentum in China's foreign economic and trade field. Promote regional economic and trade cooperation to a new level, and make institutional arrangements in the fields of industrial cooperation, rule application, and supporting guarantees. Industrial cooperation should become a key area for further leveraging institutional dividends. Through industrial cooperation, scenario innovation has more carriers, and regional industrial and supply chains can become more closely connected. Bilateral or multilateral industrial cooperation is also a practical way to enhance the competitiveness of domestic industries and conduct relevant tests on the application of rules. In addition to traditional areas of cooperation, we should explore cooperation with other RCEP member countries in the fields of technology and green industries, and consolidate the bilateral mechanism for technology transfer. On the basis of doing a good job in tariff reduction, we will refine various measures for investment facilitation and form a long-term mechanism for two-way funding. Training on the application of rules should also be strengthened. Currently, some business entities still have the problem of not understanding the rules in their use, which affects the effectiveness of the rules after they are implemented. We need to interpret policies, promote and make good use of relevant information platforms, take multiple measures to guide foreign trade enterprises to make good use of relevant economic and trade rules, improve the level of rule utilization, and avoid information asymmetry. Continuously promote supporting measures such as facilitating customs clearance. From the current reality of economic and trade connections within the region, ensuring the facilitation of customs clearance under the premise of safety and compliance plays a crucial role in promoting the integration of bilateral trade flow, capital flow, and talent flow. The widespread application of information technology has created favorable conditions for facilitating customs clearance, but the key to determining the final outcome lies in the various institutional details involved in customs clearance, the specific plans agreed upon by both parties according to rules, and the management level of frontline ports. Making specific arrangements for customs clearance facilitation will also play a doubling role in promoting regional economic and trade cooperation. (Lai Xin She)
