Abstract：The Belt and Road Initiative innovatively proposes the thought of land-sea coordination, endowing the ancient Silk Road a new connotation. Globally, land economy arises earlier and is more mature than the marine economy. Therefore, the key to land-sea coordination and the Belt and Road Initiative, at the present stage, lies in further enhancing the supporting and leading role of the marine economy. On the basis of exploring the conception of land-sea coordination for a new era, the paper proposes that China should cooperate and coordinate with the countries along the three blue economic passages in national marine development policy, infrastructure connectivity, and marine industry, which will contribute to an efficient flow of factors of production among countries along the belt and the road, shaping the win-win partnership.
