While diplomacy is a well-established topic for study, global governance is a relatively new arrival to the conceptual landscape of international relations. At first glance the two exist in separate worlds with little or no engagement between scholars of one or the other. At the most fundamental level, the absence of dialogue between diplomacy and governance derives from contrasting understandings of the nature of contemporary world politics, including the nature of globalization and the role of the state in the twenty-first century. Examining the relationship between these two concepts for the first time in a comprehensive manner, this book contains rich theoretical and case study analyses by noted academics and diplomatic practitioners.
