“Sisters in Peace”: Analyzing the Cooperation between the United Nations and the European Union in Peace Mediation

Abstract

This article examines UN–EU cooperation over peace mediation. It compares their conceptual approaches to peace mediation and the evolution of their institutional capacities, demonstrating that the EU has learned from the UN, while actively supporting the strengthening of UN mediation capacity. The most important difference concerns the embeddedness of mediation in a broader foreign policy agenda in the case of the EU compared to the UN. The article also examines models of EU–UN cooperation in mediation practice. Drawing on an overview of cases of UN–EU cooperation, the article develops a typology of the constellations through which the two organizations have engaged with and supported each other. A case study on the Geneva International Discussions on South Ossetia and Abkhazia investigates the effectiveness of this coordination. The findings point to a high degree of effectiveness, although this has not yet translated into tangible mediation outcomes.
