唐朝时期,渤海作为唐朝的边疆民族政权,与中国的邻国日本进行了长期的交往,在交往中两者有共同的利益,也有过摩擦与争执,但是友好往来始终是其主要内容。本文通过追溯两者的交往初衷、谈论其交往内容,进而阐述两者交往的意义,渤海与日本的交往满足了双方人民的经济需要,促进了唐文化的传播。 During the Tang Dynasty, Bohai Sea, as the frontier ethnic government in the Tang Dynasty, had long-term contacts with China’s neighboring Japan. Both parties shared common interests and had frictions and conflicts during their exchanges. But friendly exchanges have always been the main contents. By tracing the original intent of the two exchanges, discussing the content of their interaction and further elaborating the significance of their interaction, the interaction between Bohai Sea and Japan meets the economic needs of both peoples and promotes the dissemination of Tang culture.
