RCEP has celebrated its third anniversary of entry into force. This free trade agreement has promoted economic integration in the Asia-Pacific region. In the past, a bunch of flowers produced in Yunnan, to be exported to foreign markets, may wither or rot due to the long customs clearance time on the way, and flower companies have to bear losses; now, thanks to RCEP's customs clearance policy within 6 hours, flowers and other perishable products can complete export procedures in as fast as two to three hours, and quickly deliver to the markets of RCEP member countries, significantly improve the efficiency of cargo operation, and greatly reduce product loss rate. In the three years since the implementation of RECP, many dividends have been released. Measures such as tariff reductions and customs simplification have made trade among member countries smoother, reduced corporate costs, and increased market opportunities. RCEP regional trade has grown steadily, commodity circulation has accelerated, and consumers have enjoyed more benefits.
