Determinants of a Regional Organisation's Role in Peace and Security: The African Union and the European Union Compared

 This article presents the determinants of the influence of regional organisations in the area of international peace and security. It is aimed at initiating and provoking debate on the preponderant factors shaping that influence. The factors or determinants treated include (1) the willingness of the regional organisation to act, (2) the acceptance of its actions and (3) its capacity to discharge such peace-related tasks. The determinants are contingent on nine sub-determinants. The article uses a comparative approach, focusing on the African Union and the European Union after placing the discussion in the context of the relationship between regional organisations and the United Nations in international peace and security efforts.
