Openness is an important driving force for the progress of human civilization and a necessary path for world prosperity and development. This is the inspiration of looking back on history and also a manifestation of creating the future. As a development initiative, cooperation initiative, and opening initiative, the joint construction of the "the Belt and Road" aims to inherit the spirit of the Silk Road, work together to create an open cooperation platform, and provide new impetus for the cooperation and development of all countries. Today, from the Eurasian continent to Africa, America and Oceania, from the completion and opening of the China Laos railway, to the rejuvenation of Piraeus Port in Greece, and the opening of a new channel in the supply chain of China Europe trains... The joint construction of the "the Belt and Road" has opened up new space for world economic growth, built a new platform for international trade and investment, expanded new practices for improving global economic governance, and made new contributions to improving the well-being of people in all countries, Become China's plan to participate in global open cooperation, improve the global economic governance system, promote global common development and prosperity, and promote the construction of a community with a shared future for mankind, and become the widest and largest international cooperation platform. Practice has fully proved that the joint construction of the "the Belt and Road" pursues development, advocates win-win results, and delivers hope. The current world is intertwined with multiple challenges and crises, and the driving force for global economic recovery is insufficient. The fruitful results of the joint construction of the "the Belt and Road" tell us that only by always adhering to openness and inclusiveness, relieving the difficulties of development with openness, pooling the power of cooperation with openness, pooling the momentum of innovation with openness, and seeking the benefits of sharing with openness can we pool the joint forces of world economic growth. According to data, from 2013 to 2022, the total import and export volume between China and co built countries reached 19.1 trillion US dollars, with an average annual growth rate of 6.4%; The cumulative two-way investment with co construction countries has exceeded 380 billion US dollars. The World Bank's research report "Economics of the the Belt and Road: Opportunities and Risks of the Transport Corridor" shows that since the implementation of the joint construction of the "the Belt and Road", the cost of global trade can be reduced by 1.8% through infrastructure construction alone, which will lead to an increase of 2.8% -9.7% in trade among participating countries, 1.7% -6.2% in global trade, and 0.7% -2.9% in global income. Against the background of the surging trend of anti globalization thoughts, the joint construction of the "the Belt and Road" is committed to achieving connectivity and coordinated development of the world, further opening the arteries of economic globalization, unblocking the flow of information, capital, technology, products, industries, and people, and promoting wider and higher level international cooperation, which will certainly make important contributions to global trade facilitation and economic growth. Against the backdrop of the accelerated evolution of the century old situation, the development gap continues to widen and the governance deficit continues to increase. The successful practice of jointly building the "the Belt and Road" enlightens us that only by practicing genuine multilateralism can we promote common global development and progress and promote the development of the global governance system in a more just and reasonable direction. By the end of August 2023, more than 80 countries and international organizations have participated in the "the Belt and Road" Initiative for Trade Facilitation Cooperation launched by China. China has signed 21 free trade agreements with 28 countries and regions, and bilateral investment agreements with 135 countries and regions. Under the framework of jointly building the "the Belt and Road", Chinese and foreign partners have initiated and established more than 20 multilateral dialogue and cooperation mechanisms in professional fields, actively
