A/RES/50/81 Page 31 continue to assist Governments, at their request, to ensure implementation of national plans and strategies within the national priorities and programmes to support youth activities. As administrative overheads can reduce the resources available for technical cooperation, these should be reduced. National execution should be the preferred modality for the implementation of projects and programmes and, where required, developing countries should be assisted in improving their national capacities for project and programme formulation and execution. 137. Countries with economies in transition, when required, should also be assisted in improving their national capacities for project and programme formulation and execution. 138. The organization, on an inter-agency basis, of missions to review, assess and plan technical cooperation concerning youth, available on request to Governments, represents a specific contribution by the United Nations system to the implementation of the Programme of Action. 139. The United Nations Youth Fund represents a unique resource to support catalytic and innovative action concerning youth. Programme implementation can be furthered through the Fund’s support, in both a technical and a financial sense, of pilot action, studies and technical exchanges on issues concerning youth that encourage the participation of youth in devising and carrying out projects and whose short time-frames often make it difficult to obtain needed support from conventional budgeting processes. The capacities of the Fund for innovative action are, however, limited in the light of Programme priorities, and interested Governments, non-governmental organizations and the private sector are invited to consider the possibility of supporting the activities of the Fund on a predictable and sustained basis. To this end, the parties concerned may wish to consider the possibility of constituting an advisory body at an appropriate level to review the application of the terms of reference of the Fund and priorities and means of strengthening its capacities. 5. Outreach and partnership among specialized constituencies 140. A crucial element in implementing the Programme of Action is the recognition that governmental action alone is not sufficient to ensure its success, that rather it should be further complemented by the support of the international community. This process will also require both systematic outreach and partnership among the Programme’s many constituencies in both the non-governmental and private sectors. 141. A critical first step is phased expansion and regularization of channels of communication between the United Nations and non-governmental youth organizations to include representatives of interested private sector organizations. This would build upon the provisions set forth in General Assembly resolution 45/103 of 14 December 1990 concerning the involvement of youth and non-governmental youth organizations in the formulation of the Programme of Action. Youth, youth-related organizations and interested private sector organizations are urged to identify, in partnership with Governments, ways in which they could contribute to action at the local level to implement the Programme, and to the periodic review, appraisal and formulation of options to achieve its goals and objectives. 142. Implementation of the Programme of Action offers important opportunities to expand technical and cultural exchanges among young people through new partnerships in both the public and private sectors; to identify and test improved ways to leverage public resources, in partnership with the /...
