In international relations, reciprocity describes an environment in which States support one another for short- or long-term advantage through the balancing of rights, duties and interests. This book examines reciprocity in the context of international law. It considers the role reciprocity plays in the creation and development of international law as well as in the interpretation and application of international law. The book illuminates the reciprocal framework of international law and international relations by examining the role reciprocity plays in different types of States’ obligations, including bilateral, bilateralisable multilateral, non-bilateralisable multilateral and obligations erga omnes. The book examines how reciprocity is intertwined with the principle of equality, as the rights and obligations of States are equal irrespective of size and economic or military strength, and the beneficial effects of reciprocity in creating stability and cooperation amongst States.

"Reciprocity in Public International Law There is a common perception of reciprocity as a concept that is opposed to the communitarian interests that characterise contemporary international law, or merely a way of denoting reactions to unfriendly or wrongful conduct. This book disputes this approach and highlights how reciprocity is instead linked to the structural characteristic of sovereign equality of States in international law. This book carries out an in-depth analysis of the concept of reciprocity and the elements that characterise it, before examining the various roles and articulations of reciprocity in a number of fields of public international law: the law of treaties, the treatment of individuals, the execution of international law, and the jurisdiction of international courts and tribunals. In all these areas, it analyses both more traditional and more contemporary examples to demonstrate how reciprocity is closely linked to the very structure of public international law.

Diplomacy is transforming and expanding its role as the method of interstate relations to a general instrument of communication among globalized societies. Adapting to globalization, the practice of diplomacy is shared by non-state participants, thus becoming privatized and popularized. This book offers a comprehensive understanding of the widening scope of public as well as private diplomacy and its normative framework. It features a practitioner’s inside view of diplomacy combined with interdisciplinary academic analysis.

The first book-length study of international law through the lens of altruism.

The expectation of reciprocity continues to be an important factor when states' consider their legal obligations in armed conflicts. In this monograph, Peeler looks at the text and negotiations around the 1949 Geneva Conventions and the Protocols Additional to the Geneva Conventions from 1977 to demonstrate the many places where international humanitarian law maintains expectations of reciprocity. This complements an examination of US policy regarding its Prisoner of War obligations in both the Vietnam War and the Global War on Terror, demonstrating how states make use of the expectation of reciprocity found in international humanitarian law to respond to continued non-compliance by an enemy.
