During the Expo, the high-level forum of "RCEP and Higher Level Opening" was held in the National Convention and Exhibition Center (Shanghai), and the Agreement on Regional Comprehensive Economic Partnership (RCEP), regional economic integration, and higher level opening became the high-frequency words for the participants to discuss. At this Expo, enterprises from RCEP member countries participated in the Expo, and more and more enterprises from RCEP member countries went to the East to share the opening bonus. RCEP contributes to the development of the world economy. Yan Jinyong, Minister of Trade and Industry of Singapore, said that RCEP is the largest free trade agreement in the world, demonstrating the determination of member countries to develop a modern, comprehensive, high-quality and mutually beneficial economic partnership and further promote regional economic integration. RCEP will certainly play an important role in promoting a higher level of openness in the region and promoting sustainable and inclusive growth in the region. Deputy Prime Minister Le Wencheng of Vietnam said that RCEP is of great strategic significance. RCEP is committed to reducing tariffs and strengthening cooperation, which can bring significant economic and trade benefits to all members in the region. Professor Christopher Pisarides, winner of the Nobel Prize in Economics, believes that openness and free trade are conducive to economic development. Signing bilateral and multilateral trade agreements is a good way to break down barriers and benefit more people. RCEP is a good example. For enterprises, RCEP will greatly reduce regional tariffs in the long run, while rules of origin can bring benefits to enterprises in the short term. Rebecca Greenspan, Secretary General of the United Nations Conference on Trade and Development, said that under the circumstances of declining global openness, rising trade costs and bottlenecks in the supply chain, RCEP promotes the development of trade integration in East Asia and the Asia Pacific region, which is conducive to promoting regional and even world open cooperation and contributing to the development of the world economy. China is playing an increasingly important role in promoting global openness and cooperation and maintaining the multilateral trading system.
