regional linkage and international cooperation between the western region and ASEAN and other countries. It is not only conducive to promoting the in-depth construction and development of \"the Belt and Road Initiatives\", but it also speeds up the optimization of the spatial pattern of the western region and deepens the integration into the global value chain. According to the Master Plan for the New Land-Sea Corridor in the Western Region, the construction of corridors and freight facilities should be accelerated, the transportation capacity and the quality and efficiency of freight development should be improved, and the in-depth integration of transportation, freight, trade, and industry should be promoted. It provides strong support for promoting high-quality development and building a modern economic system in the western region [2]. As it is a major freight channel leading to Southeast Asia and even the whole world, in order to promote the realization of the above national policy goals, we should not only focus on freight construction, but also focus on the coordinated development of regional transportation and economy. The main body of the New Western Land-Sea Corridor construction in western China can be simply summarized as three major transportation systems, two major hubs, and two major ports. In 2021, a total of 6117 rail-sea combined freight trains of the new land-Sea corridor in the western region were launched, sending 570,000 tons of goods and 3347 cross-border road shuttles, constantly improving the economic benefits of the logistics hub of the new land-sea corridor in the western region. The three major transport systems are the sea-rail combined transport, cross-border highway, and cross-border railway. The sea-rail combined transport mainly connects with the international routes of ASEAN ports through three main channels: Chongqing--Guiyang--Nanning--Beibu Gulf, Chongqing--Huaihua--Luzhou--Beibu Gulf, and Chengdu--Luzhou (Yibin)--Baise--Beibu Gulf. At present, the three main channels have been formed and expanded to Dazhou, Nanchong, Fuling, and other logistics nodes, and the destinations have been expanded to 250 ports in 96 countries and regions. Cross-border highways connect Yunnan and Guangxi with Southeast Asian countries such as Myanmar, Laos, and Vietnam. At present, six routes have been opened to connect with ASEAN countries, providing full coverage of the Indo-China Peninsula. In 2020, central Asian shuttle bus routes to Kazakhstan and Uzbekistan were launched. Cross-border railway connects the railway network in Southwest China with the railway network in Southeast Asia and connects China with Indo-China Peninsula through ports in Yunnan and Guangxi. The two major hub cities are Chongqing and Chengdu. Chongqing is located at the intersection of \"the Belt and Road\" and Yangtze River Economic Belt. As the logistics and operation organization center of the channel, Chongqing will focus on the transformation of the Tuanjiecun Container Center station and Yuzui Railway freight station. As an important national trade and logistics center, Chengdu has accelerated the modernization and upgrade of Tianfu International Airport and Longquanyi railway freight station. The two ports are Beiwan port in Guangxi and Yangpu port in Hainan.
