General Secretary Xi Jinping pointed out that "the door to China's opening-up will only open wider and wider." The Decision of the Third Plenary Session of the 20th Central Committee of the Communist Party of China proposed that "opening-up is a distinctive symbol of Chinese style modernization." We must accurately understand the profound connotation of this major statement, always adhere to the basic national policy of opening up to the outside world, promote high-quality development with high-level opening-up, promote the construction of a community with a shared future for mankind, and comprehensively promote the great rejuvenation of the Chinese nation with Chinese style modernization. Openness is the only way for a country to prosper and develop. Openness leads to prosperity, while closure inevitably leads to backwardness. Since the Age of Discovery, especially after World War II, economic globalization has continued to deepen, providing unprecedented strategic opportunities for countries around the world to open up and develop. The history of hundreds of years of continuous evolution of the international landscape shows that every country that successfully achieves modernization is an economy that adopts an open development strategy. Over the past 40 years of reform and opening up in China, two miracles have been achieved: rapid economic development and long-term social stability. Practice has proven that reform and opening up is an important tool for contemporary China to catch up with the times. Openness is the proactive choice of our party. After the reform and opening up, our party established opening up to the outside world as a basic national policy, fully utilizing both international and domestic markets and resources. China has achieved a historic transformation from closed and semi closed to all-round opening up. In the new era, General Secretary Xi Jinping emphasized that "reform will not stop, and opening up will not stop". We have implemented a more proactive opening-up strategy, built a global network of high standard free trade zones, accelerated the construction of pilot free trade zones and Hainan Free Trade Port, and jointly built the "the Belt and Road" to become a popular international public product and international cooperation platform, forming a pattern of opening up in a wider range, broader fields and deeper levels. At present, China is in the critical period of comprehensively promoting the construction of a powerful country and the rejuvenation of the nation with Chinese path to modernization. We must comply with economic globalization, and promote reform, development and innovation with opening up. It is an inevitable requirement to enhance strengths and weaknesses, and fully tap into one's own economic development potential. The natural endowments of different countries vary, with their own strengths and weaknesses. Developing the economy in a closed state, as revealed by the "barrel theory," determines the scale of economic development based on its weaknesses, while the strengths cannot be fully utilized. Developing the economy under open conditions can export high-quality products with comparative advantages to the world market, in exchange for scarce resource elements, thereby lengthening the shortcomings and expanding the possibilities of economic development. Throughout the world, most countries utilize the international market for comparative advantage based exchange to complement each other's strengths. China has abundant total resources, but the per capita resources are insufficient. The overall level of energy resources per capita, such as oil, natural gas, iron ore, and arable land, is far below the world average. At the same time, our country has abundant labor resources. Since the reform and opening up, China has established the basic national policy of opening up to the outside world based on its own characteristics. It has adopted policies such as absorbing foreign direct investment, encouraging export earnings, and vigorously developing processing and trade, attracting and undertaking a large number of labor-intensive processing and assembly industries for cross-border transfer. By making good use of the advantage of abundant labor resources, China has exchanged for scarce funds, technology, resources and energy, and has embarked on a path of promoting industrialization through participation in global division of labor under the background of economic globalization, promoting rapid economic development. At present, the world's unprecedented changes in a century are accelerating the evolution. Based on the new development stage, we should lead the reform with the new development concept. We should constantly improve the level of opening up, more deeply participate in international division of labor and cooperation, promote the effective improvement of the quality of the economy and reasonable growth of quantity, and inject the power of steady development into Chinese path to modernization. Deepening division of labor and improving economic efficiency are inevitable requirements. The classic theory of international trade points out that by deepening international division of labor and conducting international trade, countries can concentrate their resources in sectors and industrial activities where they have relative advantages, which can improve their economic efficiency. With the deepening of economic globalization, international division of labor has evolved from inter industry division of labor to intra industry division of labor and even intra product division of labor, forming global industrial chains, supply chains, and value chains. China has implemented opening-up to the outside world, entering the global industrial chain from the processing and assembly of labor-intensive products, becoming a participant, beneficiary, and contributor to economic globalization, and gradually becoming an important hub node country in the global production network. With the improvement of development level, China's comparative advantage in participating in global division of labor has shifted from low-cost advantages in factors such as labor and land to advantages in human resources, industrial system, and economies of scale. It is accelerating the formation of technological innovation advantages, institutional environment advantages, and so on. To this end, we should continue to improve the level of opening up, give full play to new comparative advantages, accelerate the promotion of China's position in the global value chain, continue to improve economic efficiency and per capita income, promote high-quality development, and build a solid material and technological foundation for Chinese path to modernization. Grasping strategic opportunities and developing new quality productive forces are inevitable requirements. From historical experience, significant technological innovation and industrial transformation are important forces driving the major adjustment of the international landscape. Closing off may miss the opportunity of technological revolution and lead to falling behind and being beaten. In the history of our country, we once missed the opportunity of the Industrial Revolution due to isolationism, and slipped from being a leader in the agricultural civilization era to a laggard in the industrial civilization era. The lesson is very profound. Currently, human society is facing significant opportunities brought about by a new round of technological revolution and industrial transformation, represented by information technology. At the same time, China is working together with other countries to address various challenges and global issues facing humanity, such as climate change, which contains strategic opportunities for comprehensive green and low-carbon transformation in energy, industry, and other fields. Only by strengthening the sense of hardship, always being open-minded and adhering to the opening-up policy can we keep up with the forefront of the new round of scientific and technological revolution and industrial reform, give full play to the advantages that China has already gained in the digital economy and green economy, constantly develop new quality productivity, open up new tracks for international competition, win new advantages in international competition, and create a new situation of Chinese path to modernization. The Decision of the Third Plenary Session of the Twentieth Central Committee of the Communist Party of China (CPC) on promoting high-quality development through high-level opening proposed that "high-quality development is the primary task of building a socialist modern country in an all-round way." Focusing on the theme of promoting Chinese path to modernization and the primary task of high-quality development, the Decision made a series of strategic arrangements for improving the high-level opening up system and mechanism. To implement these strategic deployments effectively, we must adhere to promoting reform through opening up, build a new system of higher-level open economy, create a first-class business environment, and attract high-end factors to accelerate convergence; Adhere to the combination of "bringing in" and "going out", promote mutual promotion of trade and investment, promote positive interaction between domestic and international circulation, and promote high-quality development through high-level opening up. Steadily promote institutional openness and improve the quality level of two-way investment. To promote high-quality development, we must not only rely on our own conditions, but also make good use of external resources. China has many favorable conditions to attract international resources and promote high-quality development, such as a super large market, perfect infrastructure, complete industrial system, abundant human resources, and increasingly enhanced innovation capabilities. Creating a first-class institutional and business environment can double the attractiveness of these favorable conditions to international resources. The Decision of the Third Plenum of the 20th Central Committee of the Communist Party of China proposes to actively connect with international high standard economic and trade rules, create a transparent, stable, and predictable institutional environment, and create a market-oriented, rule of law, and international first-class business environment. Attracting high-end industrial activities such as research and development, regional headquarters, high-end manufacturing, and professional services, organically combining investment attraction with talent attraction, expanding international scientific and technological exchanges and cooperation, adhering to open innovation, and attracting various innovative elements to accelerate their convergence in China will enhance China's innovation and development capabilities. At the same time, Chinese enterprises are in an important period of international investment and operation. They need to organically combine the "going global" of enterprises with the promotion of high-quality development, and support enterprises to better utilize global resources to enhance innovation capabilities. Over the years, many Chinese funded enterprises have utilized external innovation resources through various forms such as establishing overseas research and development centers, overseas mergers, and international cooperation, greatly enhancing their innovation capabilities and international competitiveness. The Decision of the Third Plenary Session of the 20th Central Committee of the Communist Party of China proposes to improve the system and mechanism for promoting and safeguarding foreign investment, establish a sound management and service system for foreign investment, and promote international cooperation in industrial and supply chains. This will provide a better institutional environment for Chinese enterprises to integrate and utilize international resources to promote high-quality development. Deepen the reform of the foreign trade system and accelerate the construction of a strong trading nation. Currently, China has become a major international trading country, but there still exists the problem of being "big but not strong". For example, although the export value of goods has been ranked first in the world for many years, there is still a need to improve the position of exported products in the global value chain; The service trade has been in a long-term deficit state, and the international competitiveness of the service industry urgently needs to be enhanced. Currently, international trade is showing a trend towards digitization, greenization, and servitization, providing strategic opportunities for China to build a strong trading nation. In order to seize strategic opportunities and accelerate the construction of a strong trading nation, the Decision of the Third Plenary Session of the 20th Central Committee of the Communist Party of China proposed to deepen the reform of the foreign trade system, build a system of institutional and policy support for a strong trading nation, and so on. To implement these strategic deployments, we need to accelerate the integration reform of domestic and foreign trade, strengthen the coordination between trade policies and fiscal, financial, and industrial policies, enhance innovation capabilities, shift competitive advantages from cost advantages to technology, brand, quality, and service advantages, and vigorously improve goods trade. At the same time, we will organically combine the internationalization layout of enterprises with the construction of trade networks, vigorously develop intermediate goods trade, and enhance the competitiveness of intermediate goods exports. Secondly, we must comprehensively implement the negative list of cross-border service trade, take the comprehensive pilot demonstration of expanding the opening up of the service industry as the driving force, improve the level of liberalization and facilitation of service trade, promote the internationalization of China's service industry, especially productive service industry and technology intensive service industry, and innovate to enhance service trade. We must promote the construction of comprehensive pilot zones for cross-border e-commerce, encourage e-commerce platform enterprises to operate globally, enhance the international competitiveness of digital trade enterprises, establish efficient, convenient, and secure mechanisms for cross-border data flow, and innovate the development of digital trade. Enhance internal and external linkage effects, and accelerate the construction of a new development pattern. Accelerating the construction of a new development pattern is a strategic layout made to coordinate the overall situation of domestic and international affairs, as well as the two major issues of development and security. Building a new development pattern and achieving smooth economic circulation is the key. We must follow the deployment of the Third Plenary Session of the 20th Central Committee of the Communist Party of China, improve the circulation system, deepen the reform of the financial system, improve the resilience and safety level of the industrial chain and supply chain, ensure the smooth circulation of logistics system, financial system, industrial chain and supply chain, and enhance the endogenous power and reliability of the domestic circulation. Building a new development pattern, internal and external linkage, and mutual promotion are important contents. We must implement the deployment of the Third Plenary Session of the 20th Central Committee of the Communist Party of China on optimizing regional opening-up layout, rely on the advantages of China's super large domestic market, attract global resource elements through domestic circulation, improve the quality and level of international circulation, and enhance the linkage effect of both domestic and international markets and resources. Security is the prerequisite for development, and development is the guarantee of security. To promote high-quality development through high-level openness, we must correctly handle the relationship between development and security, firmly grasp the initiative of development, and ensure the resource security, food security, industrial security, and financial security of open development
