To promote understanding of the United Nations System and its relationship with the Lao PDR among young people, as part of the commemorations for UN Day 2009, the Ministry of Foreign Affairs and the United Nations Office of the Resident Coordinator organised a United Nations Security Council Simulation event on Thursday 22 October at ICTC. Participating delegations representing the current member countries of the Security Council consisted of 45 students in their fourth year at the National University of Laos: Faculty of Law and Political Sciences, Department of International Relations. The topic of the Security Council debate was one of the great challenges of our time – climate change as an issue of peace and security.
