A/RES/59/314 V. Strengthening the United Nations 146. We reaffirm our commitment to strengthen the United Nations with a view to enhancing its authority and efficiency, as well as its capacity to address effectively, and in accordance with the purposes and principles of the Charter, the full range of challenges of our time. We are determined to reinvigorate the intergovernmental organs of the United Nations and to adapt them to the needs of the twenty-first century. 147. We stress that, in order to efficiently perform their respective mandates as provided under the Charter, United Nations bodies should develop good cooperation and coordination in the common endeavour of building a more effective United Nations. 148. We emphasize the need to provide the United Nations with adequate and timely resources with a view to enabling it to carry out its mandates. A reformed United Nations must be responsive to the entire membership, faithful to its founding principles and adapted to carrying out its mandate. General Assembly 149. We reaffirm the central position of the General Assembly as the chief deliberative, policymaking and representative organ of the United Nations, as well as the role of the Assembly in the process of standard-setting and the codification of international law. 150. We welcome the measures adopted by the General Assembly with a view to strengthening its role and authority and the role and leadership of the President of the Assembly and, to that end, we call for their full and speedy implementation. 151. We call for strengthening the relationship between the General Assembly and the other principal organs to ensure better coordination on topical issues that require coordinated action by the United Nations, in accordance with their respective mandates. Security Council 152. We reaffirm that Member States have conferred on the Security Council primary responsibility for the maintenance of international peace and security, acting on their behalf, as provided for by the Charter. 153. We support early reform of the Security Council - an essential element of our overall effort to reform the United Nations - in order to make it more broadly representative, efficient and transparent and thus to further enhance its effectiveness and the legitimacy and implementation of its decisions. We commit ourselves to continuing our efforts to achieve a decision to this end and request the General Assembly to review progress on the reform set out above by the end of 2005. 154. We recommend that the Security Council continue to adapt its working methods so as to increase the involvement of States not members of the Council in its work, as appropriate, enhance its accountability to the membership and increase the transparency of its work. Economic and Social Council 155. We reaffirm the role that the Charter and the General Assembly have vested in the Economic and Social Council and recognize the need for a more effective Economic and Social Council as a principal body for coordination, policy review, 32
