International Negotiation: A Journal of Theory and Practice examines negotiation from many perspectives, to explore its theoretical foundations and to promote its practical application. It addresses the processes of negotiation relating to political, security, environmental, ethnic, economic, business, legal, scientific and cultural issues and conflicts among nations, international and regional organisations, multinational corporations and other non-state parties. Conceptually, the Journal confronts the difficult task of developing interdisciplinary theories and models of the negotiation process and its desired outcome. Analytically, it publishes a broad selection of original research articles, traditional historical and case studies, and significant contributions to the expanding body of knowledge in the field. In general terms, the Journal’s practical aim is to identify, analyse and explain effective and efficient international negotiation and mediation processes that result in long-lasting, flexible and implementable solutions.
