International negotiations have become an increasingly widespread feature of international affairs. Cecilia Albin argues that negotiators do not simply pursue their narrow interests or those of their countries, but regularly take principles of justice and fairness into account. Her analysis is based on cases in four important areas: the environment, international trade, ethnic conflict, and arms control. Drawing on a mass of empirical data, including a large number of interviews, she relates the abstract debate over international norms and ethics to the realities of international relations.
