The United Nations Resident Coordinator Office provides direct support to the UN Resident Coordinator and the UN Country Team, including advisory, technical, organizational and management support.

The resident coordinator system (RCS) encompasses all organizations of the UN system In Serbia. The Resident Coordinator is the designated representative of the Secretary-General and leader of the UN Country Team. The Bretton Woods institutions and other international organizations, as appropriate, are encouraged to be closely associated with the RCS/country teams. UNDP manages the RCS.

The principle guiding the coordination of activities, emanates from the General Assembly and it establishes that the host Governments have the primary responsibility for coordinating, on the basis of national strategies and priorities, all types of external assistance, including that provided by multilateral organizations.

The RCS seeks to better coordinate the operational activities for development of the UNS and their integration with national plans and priorities. The aim of this coordination function is to ensure that the UNS operational activities contribute effectively to national development, providing a flexible response to the host country's need, aiming at maximizing the overall impact of UNS support. These activities are carried out for the benefit of the host country, at its request, and in accordance with its own policies and priorities for development. Moreover, RCs, in full consultation with the national governments and recognizing their primary responsibility for the implementation and evaluation of conference follow-up, assist the national governments in carrying out this responsibility by facilitating a coherent and coordinated UNS follow-up to major international conferences at the field-level. The RCS is expected to support the government's responsibility for coordination by building national capacity as required. The RCS through the RC may be asked to provide support in carrying out some of these responsibilities and to maintain formal or informal contact with the donor community.
This also involves participation in Consultative Group Meetings and Round Table processes.
