Chapter 4 discusses the logic of order of the Chinese tributary system. It demonstrates that a shared set of collective beliefs, revolving around Confucian principles, and other norms, played an integral role in this political system. Understood as a complex of shared understanding and meaning, tributary relations acted as a lingua franca by creating a shared script, a common knowledge, that facilitated mutual understanding, which could entail benign or less benign relations but overall provided actors with a common frame of reference. The tributary system is an analytical framework for the historical study of Asian international relations, a concept that should be understood as a script that allowed for multiple and diverse interpretations by the participants themselves. The chapter further demonstrates how the Sinocentric system could accommodate great heterogeneity and multiple ethnicities and religions.
