The United Nations (UN) Department of Political Affairs and the European Union (EU) External Action Service co-hosted the second technical expert workshop on “Operationalizing mediation support within intergovernmental organizations – sharing experience and good practice” in Nairobi, Kenya, 17-19 October 2018. The retreat brought together participants (eight women and seven men) from ten organizations: the Africa Union, the Commonwealth, the East African Community, the Economic Commission of Central African States, the EU, the Intergovernmental Authority for Development, the Organization of American States, the Organization of Islamic Cooperation, the Organization of Security and Cooperation of Europe, and the UN to share good practice, approaches to and tools of mediation and dialogue support. These organizations were invited on the basis of having either an existing mediation support office1 or a commitment to establish such a capacity.
