The transportation of goods in international trade needs to be transported by various major channels. The new international landsea trade channel is a strategic channel connecting the Yangtze River Economic Belt and the “Belt and Road” interconnection between China and Singapore，and is an important carrier for promoting a new round of development in the western region and is also an important link to build a ChinaASEAN community with a shared future. This article analyzes and combs the spatial orientation structure，time structure and spatial capacity structure of the new international landsea trade channel，and points out its main radiating provinces industrial structure development，infrastructure construction，and related policies issued by the country and the local government. The new sea trade channel is widely used to facilitate the development of international trade in the western region and provide a reference for the vigorous development of the western landsea trade channel.
