This is a serious challenge to the Organization, requiring timely mobilization of human, financial and logistical resources. A spirit of partnership is required for effective management, and Member States and the Secretariat have complementary roles to play, the Secretary- General states. Harmonization of political, social and developmental efforts can increase the effectiveness of peacekeeping operations, ensure smooth continuation of efforts after their withdrawal, and reduce duplication during deployment of complex peacekeeping operations. The Secretariat is continuing to strengthen coordination with specialized agencies and regional organizations. Other examples include the joint assessment mission led by the World Bank in East Timor and the joint approach to donors for East Timor by the World Bank and the United Nations through the Tokyo Conference.
Several operations exemplify partnerships with regional efforts.
The Organization's new or expanded operations in Kosovo, Federal Republic of Yugoslavia, East Timor, Democratic Republic of the Congo and Sierra Leone, together with ongoing operations in Bosnia and Herzegovina, Georgia and Tajikistan, exemplify such partnerships with regional efforts, whether taken through or outside the established institutional framework of a regional organization. These experiences have testified to the fact that the primacy of the Security Council remains essential. Both organizations are working under the authority of the Special Representative of the Secretary- General. This experience may provide useful guidance for other joint efforts with regional organizations in the future. However, the Secretary-General warns that regardless of the arrangements made within any particular mission, cooperation between the United Nations and regional organizations inevitably poses considerable challenges.
