This research report presents a political-economy analysis of the Peace and Security Council, the principal decision-making body of the AU on matters of peace and security in Africa. It is the aim of the report to shed light on the PSC decision-making processes and how decisions are shaped and by who. Understanding the interdependencies between the various actors involved, their interests and motivations as well as factors that could change their behaviour in matters pertaining to conflict resolution is an important ingredient for an improved and more sustainable policy response by the AU.
