A/RES/66/288 facilitate the mobilization of resources and their effective use in achieving sustainable development objectives. 256. An intergovernmental committee, comprising thirty experts nominated by regional groups, with equitable geographical representation, will implement this process, concluding its work by 2014. 257. We request the General Assembly to consider intergovernmental committee and take appropriate action. the report of the 258. We recognize that the fulfilment of all commitments related to official development assistance is crucial, including the commitments by many developed countries to achieve the target of 0.7 per cent of gross national product for official development assistance to developing countries by 2015, as well as a target of 0.15 to 0.20 per cent of gross national product for official development assistance to the least developed countries. To reach their agreed timetables, donor countries should take all necessary and appropriate measures to raise the rate of aid disbursements in order to meet their existing commitments. We urge those developed countries that have not yet done so to make additional concrete efforts towards the target of 0.7 per cent of gross national product for official development assistance to developing countries, including the specific target of 0.15 to 0.20 per cent of gross national product for official development assistance to the least developed countries, in accordance with their commitments. To build on progress achieved in ensuring that official development assistance is used effectively, we stress the importance of democratic governance, improved transparency and accountability, and managing for results. We strongly encourage all donors to establish, as soon as possible, rolling indicative timetables that illustrate how they aim to reach their goals, in accordance with their respective budget allocation process. We stress the importance of mobilizing greater domestic support in developed countries towards the fulfilment of their commitments, including by raising public awareness, providing data on the development impact of aid provided and demonstrating tangible results. 259. We welcome increasing efforts to improve the quality of official development assistance and to increase its development impact. We also recognize the need to improve development effectiveness, increase programme-based approaches, use country systems for activities managed by the public sector, reduce transaction costs and improve mutual accountability and transparency, and in this regard we call upon all donors to untie aid to the maximum extent. We will further make development more effective and predictable by providing developing countries with regular and timely indicative information on planned support in the medium term. We recognize the importance of efforts by developing countries to strengthen leadership of their own development, national institutions, systems and capacity to ensure the best results for effective development by engaging with parliaments and citizens in shaping those policies and deepening engagement with civil society organizations. We should also bear in mind that there is no one-size-fits-all formula that will guarantee development effectiveness. The specific situation of each country needs to be fully considered. 260. We note that the aid architecture has changed significantly in the current decade. New aid providers and novel partnership approaches, which utilize new modalities of cooperation, have contributed to increasing the flow of resources. Further, the interplay of development assistance with private investment, trade and new development actors provides new opportunities for aid to leverage private resource flows. We reiterate our support for South-South cooperation, as well as triangular cooperation, which provide much-needed additional resources to the 49
