The pandemic is still raging around the world，economic globalization encounters a countercurrent，international trade and investment shrink substantially，and economy slides towards recession in all countries. In the future，international competition may focus on supply chain and industry chain. By spurring and coordinating business activities of manufacturers，distributors and buyers through China International Import Expo（CIIE），we could realize the integration and guidance of global supply chains and industry chains，help upstream and downstream industries in the Yangtze River Delta to make up for weaknesses and develop strengths in domestic and international industry chains and supply chains，and eventually realize consumption upgrading and industrial upgrading. With the goal of building a new development pattern，we’ ll build the Yangtze River Delta into a hub of the domestic circulation and a strategic link of domestic and international circulations.
