Global Perspectives on Organizational Conflict by Rahim and Blum (1994) might be useful. But it focuses on organizational conflict and it sounds like you might be interested in international conflict.

I hope some of this could be useful: 1.Mediation and Dialoque Faciliation in the OSCE,  Reference Guide, OSCE 2014, http://www.osce.org/secretariat/126646 ; 2.Bothe Michael, Ronzitti Natalino, Rosas Allan (eds.): The OSCE in Mantenance of Peace and Security, Kluwer Law International 1997;; 3.Schneider Patricia, Müller-Wolf Tim J.
