This is the first book to apply the concept of good international citizenship to the international relations of the Global South. The edited book introduces good international citizenship as a theoretical framework for analysing a diversity of agencies across the Global South. It covers different cases of non-Western states, global governance, foreign policy, and international law, and examines how non-Western actors enact ideas of good international citizenship to engage and shape the global order. The book shows how good international citizenship is not limited to Western notions of liberal internationalism but also encompasses the efforts of non-Western actors to promote distinct approaches to ethics, morality, responsibility, and leadership. The book contributes theoretically and empirically to the field of non-Western International Relations. It allows for rethinking established International Relations concepts so that these become more inclusive to the histories and experiences of different actors across the globe.
