Using recent archaeological findings and little-known archival material, Wang Zhenping introduces readers to the world of ancient Japan as it was evolving toward a centralized state. Competing Japanese tribal leaders engaged in ambassador diplomacy and actively sought Chinese support and recognition to strengthen their positions at home and to exert military influence on southern Korea. Wang brings diplomatic history to life in his descriptions of the diplomats and their personalities and literary talents as well as their ambitions and frustrations. He explains in detail the rigorous criteria of the Chinese and Japanese courts in the selection of diplomats and how the two prepared for missions abroad. He journeys with a party of Japanese diplomats from their tearful farewell party to hardship on the high seas to their arrival amidst the splendors of Yangzhou and Changan and the Sui-Tang court. The depiction of these colorful events is combined with a sophisticated analysis of premodern diplomacy using the key concept of mutual self-interest and a discussion of two major modes of diplomatic communication: court reception and the exchange of state letters. accepting, or rejecting court ceremonial arrangements.
