Since the outbreak of the new crown epidemic，the Chinese government has quickly controlled the spread of the epidemic with a nationwide effort and promoted the full restoration of production and living order. It has become one of the few economies that maintain economic growth under the impact of the epidemic. In the context of the global economic downturn，the Chinese economy has become the “locomotive” of the world economic recovery with an exciting V-shaped rebound curve. China’s outstanding anti-epidemic effect has injected strong impetus into the restart of the world economy. The strong resumption of work and production has maintained the stability of the global industrial chain and supply chain，laying an important foundation for the recovery of the global economy. Against the background of the epidemic，China firmly promotes the “Belt and Road” initiative，and continues to create a good cooperation environment for countries along the route to help developing countries get out of the haze of the epidemic. The “double-cycle” development strategy launched by the Chinese government based on the complex economic forms at home and abroad，while maintaining the high-quality and sustainable development of its own economy，has also brought new growth expectations to the world economy.
