Northeast Asia experieces a rapid economic development with a huge development potential. Since the Belt and Road Initiative was put forward, the cross-border trade of Asian countries increases rapidly. The cross-border logistics corridor is an important support to promote the regional economic cooperation, and to achieve the mutual benefit and the win-win results. This paper reviews the development status and the existing problems of the land cross-border logistics corridor in Northeast Asia, forecasts the development direction of the land cross-border logistics corridor in Northeast Asia under the Belt and Road Initiative, and puts forward measures and suggestions from the perspective of the integrated transportation, such as improving the channel infrastructure, improving the transport organization, and improving the level of the customs clearance facilitation.
