Tianjin is located on the west coast of the Pacific Ocean, in the convergence zone of the Beijing-Tianjin-Hebei Urban Agglomeration and the Bohai-Rim Economic Circle. It is also the meeting point between the eastern Land Silk Road and the northern Maritime Silk Road in the Belt and Road Initiative, as well as a starting point of the Sino-Mongolian-Russian Economic Corridor. Backing onto North, Northeast and Northwest China, it boasts vast economic hinterland. Facing Northeast Asia and the Asia-Pacific economic circle, it is an important window for China's participation in regional economic integration and economic globalization, as well as a channel for landlocked countries to have access to the sea. Tianjin Port sea routes now cover all the major ports in the world; the world's top 3 shipping alliances have all opened their largest liner lines with Tianjin Port.
