魏晋南北朝时期的海上交通活动相当活跃,特别是东吴、刘宋和萧梁等朝。当时与海外的交往和交流主要表现为使节往来、贸易和佛教文化传播等几个方面。贸易活动和佛教交流呈恒温态势,而使节往来则是时有盛衰断续进行的,但比之汉代交通的海外国家从数量上大有增加,与东南亚诸国的交往比之前代更加频繁。尽管东汉时大秦至洛阳的商道已经为罗马人所走通,但两晋以后,便没有中国与罗马或拜占廷之间海上交通的记录,南朝诸朝交往的海外国家最远才是天竺、师子国。东夷方面,与朝鲜半岛诸政权间的交往有加强趋势,而与倭国之间则呈衰退之势。 The maritime traffic activities in the Wei, Jin, Southern and Northern Dynasties were quite active, especially the Dongwu, Liu Song and Xiao Liang. At that time, exchanges and exchanges with overseas mainly manifested in several aspects such as diplomatic relations, trade and the spread of Buddhist culture. The exchange of trade and Buddhism was at a constant temperature, while the flow of envoys between the two was frequent. However, compared with the Han countries, the number of overseas countries greatly increased and their contacts with Southeast Asian countries were more frequent than before. Although the trade routes of the Dahan Qin Dynasty to Luoyang in the Eastern Han Dynasty were already passed by the Romans, there was no record of maritime traffic between China and Rome or the Byzantine after the Jin and Jin Dynasties. The most distant overseas countries to which the Southern Dynasties were affiliated were Tianzhu, Sub-countries. In the area of ​​Dongyi, exchanges with the regimes in the Korean Peninsula have been strengthened, and the trend toward recession with Woguo has been declining.
