Since the 18th National Congress of the Communist Party of China, General Secretary Xi Jinping has coordinated the two aspects of thenew normal", scientifically managed the dialectical relationship between development and security, openness and autonomy, and proposed to build a new pattern of development that is "domestic circulation as the body and domestic and international circulation promoting each other". The report of the 20th National Congress of the Communist Party of China clearly put forward the "advance high- opening-up", and the Fourth Plenary Session of the 20th Central Committee of the Communist Party of China further emphasized "expanding the international cycle, promoting reform development through opening-up" and "actively expanding autonomous opening-up and promoting the innovation and development of trade". This series of important expositions systematically elaborated the direction and of expanding the international cycle and expanding autonomous opening-up, and profoundly revealed their important role in promoting the overall situation of Chinese-style modernization. At present, the world is unprecedented changes, economic globalization is facing counter-currents, and the scientific and technological revolution and industrial transformation are deeply restructuring the global competitive pattern. Expanding the international cycle expanding autonomous opening-up is China's strategic choice to grasp the initiative and shape the future in the changing situation. Only by enhancing independent capacity in a higher level of opening- and expanding the space for development in a broader international cycle can we cope with changes with opening-up, manage risks with cooperation, and win the future with innovation, and contribute Chinese and Chinese strength to building an open, inclusive, and win-win world economy.

Deeply understand the far-reaching significance of expanding the international cycle and expanding autonomous opening-up
Expanding international cycle and expanding autonomous opening-up has become China's strategic choice to coordinate development and security and achieve high-quality development. This measure not only fits the inherent law China's economic development in the new era, but also demonstrates China's major country responsibility of benefiting each other and developing together with all countries in the world.
 inevitable requirement of building a new development pattern. Building a new development pattern with domestic circulation as the main body and domestic and international circulation promoting each other, the essence is to enhance the of the domestic market and the efficiency of international resource allocation, to play a coordinated role of the two, and to solve the structural contradictions faced in development. Expanding the international and expanding autonomous opening-up, as the core content of building a new development pattern, emphasize the domestic cycle through open empowerment and the international cycle through the domestic cycle, and an organic unity of the "main body" and the "two wings". From the perspective of theoretical logic, the domestic big cycle is the foundation and confidence of the international cycle The advantages of the super large market, the complete industrial system, and the continuously upgraded domestic demand structure provide stable demand support and supply guarantee for the international cycle; the international cycle is extension and promotion of the domestic big cycle. By expanding the international market space and gathering global high-quality resources, it can not only make up for the shortcomings of domestic high- factor supply, but also improve the quality and efficiency of domestic circulation. The two depend on each other, promote each other, and are unified in the process of promoting high-quality development, reflecting the dialectical unity of adhering to independence and expanding opening-up.
The key measure to support the overall pattern of Chinese-style modernization.anding the international cycle and expanding autonomous opening-up injects momentum into modernization construction through internal and external synergy and double empowerment. By expanding autonomous opening-up, deepseated institutional and mechanism reforms can be forced, obstacles restricting the release of domestic demand potential can be eliminated, and endogenous development momentum can be enhanced; by expanding the international cycle it is conducive to participating in global resource allocation in a wider range and at a higher level, promoting the gathering of elements such as technology, talent, and capital to the market, and providing important support for promoting scientific and technological innovation and industrial upgrading. The benign interaction between the international cycle and autonomous opening-up not only promotes the achievements of Chinesestyle modernization to benefit all the people, but also creates broad opportunities for all countries in the world to share development dividends and provides solid support for building an open and inclusive global development.
The strategic path to win a new edge in international competition. The current global industrial landscape is undergoing profound reconstruction, and the competition institutional rules and the level of openness has become an important part of international competition. China's opening up to the outside world is transitioning from an open type driven by the flow factors to an open type based on institutional rules. By proactively aligning with high-standard international economic and trade rules and steadily expanding the open type based on institutional rules such as, regulations, management, and standards, China can enhance its voice and influence in international economic governance, better adapt to the trend of reshaping the global industrial and supply chains, and the development of manufacturing industry towards high-end, intelligentization, and greening. By strengthening and optimizing foreign trade, and ensuring the smooth operation of the international circulation, China give full play to its comprehensive advantages of a complete manufacturing system and strong supporting capabilities, achieve the optimization and upgrading of the industrial and supply chains, and win the initiative, the edge and the future in the fierce international competition.
China's proposal to promote the healthy development of economic globalization. China's commitment to expanding the international circulation and its opening-up is not only a conscious adherence to the regularity of economic globalization but also an important contribution to global economic development. By promoting the liberalization and facilitation trade and investment, deepening bilateral and multilateral economic and trade cooperation, and actively participating in the reform and construction of the global governance system, China has provided a pragmatic and path to address the global development deficit and the governance deficit. Autonomous opening-up means that China will always be in the driver's seat of opening-up, and according its development needs and actual conditions, it will scientifically determine the rhythm and mode of opening-up. This embodies the firm determination of the Party Central Committee to promote high-level-up, as well as its accurate grasp of the national conditions and the stage of development, and contributes Chinese wisdom and Chinese strength to promoting economic globalization towards a more open,, beneficial, balanced, and win-win direction. 
Expand the international circulation to better expand autonomous opening-up
Expanding the international circulation can expand the space for autonomous opening-up. On the one hand, expanding the international circulation can promote the flow and allocation of resources in the international market, promote the in-depth participation Chinese enterprises in the division of global industrial and supply chains, expand the development space for enterprises, help to release the advantages of China's manufacturing industry in the global market, and a modern industrial system with international competitiveness. At the same time, as international capital and technology flow in, the domestic industrial chain is constantly leaping to the middle and high end, helps to improve China's position in the global industrial chain and promote the deepening of autonomous opening-up in various fields. On the other hand, expanding the international circulation can China to cultivate emerging markets, deepen the cooperation framework of "the Belt and Road", the Regional Comprehensive Economic Partnership (RCEP), etc., transform the expansion of the international circulation into a realistic channel for autonomous opening-up, and form a diversified and balanced trade partner pattern, and promote interconnectivity with all countries in world.
Improve the endogenous capacity of autonomous opening-up through a higher quality international circulation. Firstly, by steadily expanding market access and attracting multinational companies to arrange R&D centers in China, we can introduce their advanced technologies and management experience, and produce a "spillover effect". Secondly, the fierce competition brought by the highquality international circulation is the key force to drive the deep integration of scientific and technological innovation and industrial innovation. In this process, China can not only enhance its industrial competitiveness but also improve independent innovation capability, thus forming new advantages in the opening-up.
Consolidate the security foundation of autonomous opening-up through a more stable international circulation. Secretary Xi Jinping emphasized that "the more we expand opening-up, the more we need to coordinate development and security, and firmly adhere to the bottom line of security".anding the international circulation is an important means to keep the bottom line of security for autonomous opening-up. First, by building the "the Belt and Road" high-quality, exploring emerging markets, and establishing diversified trade and investment ties. Second, by relying on the advantages of China's super-large market and a complete industrial system, the global and supply chains can be laid out in depth in China through the international circulation, thus forming a community of interests in which "you have me and I have you". Third, stable operation of the domestic circulation also needs the international circulation to provide key elements and market space. A safe and stable international circulation can in turn promote the development of the domestic circulation
Elevating the discourse on autonomous opening-up to a higher level of international circulation. By jointly building the "the Belt and Road" initiative with quality, promoting green and low-carbon cooperation and digital economy cooperation, and expanding unilateral opening-up to the least developed countries, China has not only provided global public goods for development, but also demonstrated the image of a responsible big country. At the same time, by actively participating in and promoting the formulation of rules in the field of digital trade, governance and other fields, China has enhanced its voice and influence in global economic governance. Consequently, the level and quality of autonomous opening-up has significantly improved, and a stronger strategic has been formed in responding to global economic uncertainties and building an open world economy.
