Multilateral Diplomacy is an in-depth course on a wide spectrum of aspects of such diplomatic sphere, ranging from its history to its actors, rules, methods or processes. Focusing on the United Nations and their main organs as examples (but not only), the course covers a comprehensive analysis of all these issues through the study of actual UN documents, and through discussions about ongoing debates on new developments and reforms. A balanced combination of practical and academic perspectives, and constant interaction with peers and devoted and encouraging lecturers from both fields, make this course really useful both for practicing diplomats and students coming from other backgrounds, like me.
