Wang Wenqi's long ancient Silk Road has witnessed the prosperity of "envoys facing each other on the road, and business travel on the road". Today, the key to jointly building the "the Belt and Road" is connectivity, and the cornerstone is infrastructure. Since the "the Belt and Road" initiative was put forward ten years ago, under the strategic guidance and strong promotion of President Xi Jinping, infrastructure connectivity has achieved fruitful results, and the radiation driving effect is constantly emerging, which has become a strong support for the solid promotion and lasting development of the "the Belt and Road" construction, and connected and realized the happy dream of people along the line. Open up key channels and continuously improve the interconnection network. The joint construction of the "the Belt and Road" has established the connectivity framework of "six corridors, six roads, multiple countries and multiple ports", focused on opening up key channels and nodes, and led by major projects and key projects, constantly promoted infrastructure construction in the fields of roads, railways, ports, aviation, oil and gas pipelines, and power. Such landmark projects as the Addis Ababa Djibouti Railway, the Mombasa Nairobi Railway, the China Laos Railway, the Ya'an Wanzhou High speed Railway, and the China Russia East Line Natural Gas Pipeline have been successfully completed and have yielded benefits. Projects such as the Hungary Serbia Railway, the China Kyrgyzstan Ukraine Railway, Gwadar Port, and Piraeus Port have progressed smoothly and achieved remarkable results. Laos and other countries have transformed from a "land-locked country" to a "land-locked country"; Kazakhstan has had its first sea passage; The China Europe freight train has transformed from "connecting points into a line" to "weaving threads into a network", becoming an international transportation artery that basically covers the entire territory of the Eurasian continent... These achievements have greatly reduced the cost of economic and trade exchanges between regions, effectively promoting the orderly flow and optimized allocation of resource elements across regions. Promote industrial agglomeration and effectively drive the development of the real economy. The joint construction of the "the Belt and Road" is based on connectivity projects, adheres to the principle of joint consultation, joint construction and sharing, grasps the correct direction of government guidance, enterprise decision-making and commercial operation, and actively promotes industrial cooperation along the line. A large number of cooperation parks, including the China Belarus Industrial Park, Sihanouk Port Special Economic Zone, and Gwadar Port Free Zone, have been successfully promoted, forming a comprehensive effect of infrastructure leadership, industrial agglomeration, economic development, and people's livelihood improvement, effectively promoting international production capacity and equipment manufacturing cooperation. Adhere to the combination of "hard" and "soft", and promote high-quality cooperation project construction. While promoting the "hard connectivity" of infrastructure, the joint construction of the "the Belt and Road" also actively promotes the "soft connectivity" of rules and standards. China has established dozens of multilateral dialogue and cooperation platforms in areas such as the China Europe train, promoting the compatibility of rules and standard systems among countries; Continuously promote the connectivity of customs, quality inspection, quarantine, accounting and other software, and carry out information exchange, regulatory mutual recognition, and law enforcement mutual assistance with co construction countries; We are also conducting rule and standard docking in emerging fields such as vaccine research and development, green development, digital economy, and technological innovation. These actions to accelerate the integration of hardware and software have created a new pattern of interconnected development. Pay attention to keeping up with the times and strive to create three-dimensional green connectivity. China is accelerating the integration of green development concepts into infrastructure operation, management, and maintenance processes, promoting the realization of green connectivity. China not only continues to promote energy-saving and low-carbon transportation tools such as new energy and clean energy vehicles and ships, but also initiated the establishment of the "the Belt and Road" International Alliance for Green Development with international partners, and built the "the Belt and Road" ecological and environmental protection big data service platform to help jointly build the country to improve environmental governance
