The mainstream studies of the East Asian tributary system have been exhibiting a stance that tends to stress the importance of Confucianism in forming and sustaining the tributary system throughout its long history. However, there are still several questions (especially those of a theoretical nature) that historians have yet to answer: How could Confucianism have contributed to the formation and sustenance of this tributary system? Why could this Confucian-based tributary system be recognized and employed in relations with non-Confucian frontier tribes? Why could this system have worked with both the nomadic tribes on the northern frontier and the South-East Asian countries that were neither Confucian nor nomadic? Drawing on the results of ritual studies in anthropology, Chinese historiography and Chinese philosophy, this author seeks a broader methodology that can be used to conceptualize the tributary ritual and its constitutive power structure, which forms the foundation of the central part of the East Asian world order. This paper is a theoretical attempt to find a non-Sinocentric way to interpret the formally Sinocentric tribute system in premodern East Asia.
