Mainstream studies of diplomacy have traditionally approached international relations (IR) using realist and neorealist frameworks, resulting in state-centric analyses of mainly political agendas at the expense of economic matters. Recently, however, scholars have begun to focus on understanding international relations beyond security. Consequently, there has been a significant shift in the study of diplomacy toward a better understanding of the processes and practices underpinning economic diplomacy. New concepts of diplomacy such as catalytic diplomacy, network diplomacy, and multistakeholder diplomacy have emerged, providing new tools not only to recognize a greater variety of state and nonstate actors in diplomatic practice, but also to highlight the varied and changing character of diplomatic processes. In this context, two themes in the study of diplomacy can be identified. The first is that of diplomat as agent, in IR and international political economy. The second is how to fit into diplomatic agency officials who do not belong to the state, or to a foreign ministry. In the case of the changing environment caused by globalization, economic diplomacy commonly drives the development of qualitatively different diplomatic practices in new and existing economic forums. Four key modes of economic diplomacy are critical to managing contemporary globalization: commercial diplomacy, trade diplomacy, finance diplomacy, and consular visa services in relation to increased immigration flows. The development of these modes of economic diplomacy has shaped the way we think about who the diplomats are, what diplomats do, and how they do it.
