明太祖朱元璋基于“宗藩”地缘政治理念和明初的地缘政治形势,确立了明朝对外政策两大支柱——海禁政策和朝贡贸易。他的后世子孙根据地缘政治形势的变化,对涉外政策进行调整,这种调整反过来又影响到明朝的地缘政治形势,二者在东亚“宗藩”地缘政治格局内互动。 Ming Taizu Zhu Yuanzhang established the two pillars of the Ming Dynasty’s foreign policy - the ban on sea trade and the tributary trade based on the geopolitical ideas of “suzerainty” and the geo-political situation in the early Ming Dynasty. His later sons and daughters adjusted the foreign policy according to the changes in the geo-political situation. In turn, this adjustment affected the geo-political situation in the Ming Dynasty. Both of them interacted within the geo-political pattern of East Asia.
