United Nations Security Council Resolution 2167, concerning the critical role of regional cooperation in International Peacekeeping and Security was adopted unanimously on 28 July 2014. The resolution originated through a debate initiated by the Permanent Representative of Rwanda by sending a letter dated 3 July addressed to the Secretary-General. The 15 member body emphasised that concrete steps should be taken by United Nations and regional organisations (especially the African Union) to strengthen their relationships and develop more effective partnership.
