Abstract:  Throughout history it is selfevident that no country has expanded sea power without the strategic support of overseas bases. It is sensible to say that a powerful naval fleet is the core of sea power, but the guarantee and control of the safety of the maritime fairways and strategic channels is dependent on overseas bases, which are the key element, pillar and footing stone of sea power strategy. Zheng He’s Voyages in Ming Dynasty were farsighted and prudent planning and deployment of overseas bases, which become the strong and powerful pillar of sea power strategy of Ming Dynasty, preserved and safeguarded its maritime rights, expanded China’s influence in the world. What’s more, Zheng He’s sea power strategy, in comparison with the Western fireandsword style of colonized sea power, has more profound implications and significance for the construction of contemporary sea power. At present, China should preserve and safeguard national sea rights and interests while shouldering responsibilities as a big nation and providing international public products. All of this calls for the establishment of overseas bases with the purpose of international security and peace.
