The Fifth Plenary Session of the 18th CPC Central Committee clearly defined the new development concept of innovation, coordination, green, openness and sharing. Innovation is the first driving force for development, coordination is the internal requirement for sustainable and healthy development, green is the necessary condition for sustainable development and the important embodiment of the people's pursuit of a better life, opening is the only way for national prosperity and development, and sharing is the essential requirement of socialism with Chinese characteristics. After China enters the new development stage, the complete, accurate and comprehensive implementation of the new development concept is of great practical significance to the realization of the long-term goal of 2035, both in theory and in practice. Historically, both the land Silk Road and the maritime Silk Road have played an important role in promoting China's economic and cultural prosperity. The introduction of cotton, sweet potato, corn and other crops has made a significant contribution to China's agricultural production. The continuous inflow of silver contributes greatly to the stability of the monetary system. Dunhuang culture is an important crystallization of Sino Western exchanges. The output of the compass provides technical support for the era of navigation, and tea, porcelain and other products enjoy a good reputation in the West. Similarly, an important factor for China to achieve remarkable development achievements is to adhere to reform and opening up, learn from advanced Western technologies and actively integrate into the global economic and trade system. In 2013, China became the world's largest trade country in goods. In 2021, the scale of China's imports and exports reached a record high of 6.05 trillion US dollars. Foreign trade played an important role in driving the country's economic development. In 2021, China's actually utilized foreign capital in RMB will exceed one trillion yuan for the first time, reaching 1149.36 billion yuan, up 14.9% year on year. At the same time, China has also made some progress in the process of RMB internationalization, and the proportion of payment currency, transaction currency, reserve currency and other aspects has increased. The above historical facts fully illustrate the basic fact that opening up is the only way for a country to prosper and develop. Only by adhering to reform and opening up, and learning from each other, can we achieve prosperity and development together, maintain China's economic and cultural prosperity, and achieve the strategic goal of "two steps" development in the new era. At present, China has entered a new stage of development, and continuing to deepen reform and expand opening up is an important basis for building a new development pattern. It is a major strategic task for China to fully grasp, accurately understand and fully implement the new development concept, and build a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other. The international circulation is not only a strategic need for China to continue to deeply participate in and promote the process of globalization, but also an important way for China to fully learn and learn from foreign advanced technology and experience, further enhance China's position in the division of labor in the global industrial chain, promote the transformation and upgrading of the domestic economy and industrial structure, and achieve the strategic objectives of the new development stage. To implement the dual cycle development strategy, we should not only attach importance to building a domestic large cycle development system, but also attach importance to building an international cycle system. Only two wheel drive can achieve stable development. To do this, we need
