The field of international peace mediation has become increasingly complex. Proliferation of actors that are able and willing to mediate has made multiparty mediation a standard format through which conflicts get managed. Due to their ad hoc nature, multiparty mediation efforts require specific mechanisms that will provide sufficient clarity and direction for the mediators involved. This paper departs by differentiating three distinct, yet highly interrelated, fundamental aspects that contribute to the overall success in multiparty mediation: cooperation, coordination and leadership. Treating coordination as a subset element of wider cooperation, this paper addresses the main challenges of achieving effective coordination in a given context. The paper highlights the relevance of information carrying capacity and premediated appointment of a leader when developing particular coordination mechanisms.
