Joint Declaration on UN/NATO Secretariat Cooperation

The Secretary-General of the United Nations and the Secretary General of the North Atlantic Treaty Organization, welcoming over a decade of cooperation between the United Nations and NATO in support of the work of the United Nations in maintaining international peace and security, and desiring, in the spirit of the 2005 World Summit Outcome, to provide a framework for expanded consultation and cooperation between their respective Secretariats, have agreed to the following:

1. We, the Secretary-General of the United Nations and the Secretary-General of the North Atlantic Treaty Organization, reaffirm our commitment to the maintenance of international peace and security.

2. Our shared experiences have demonstrated the value of effective and efficient coordination between our Organizations. We have developed operational cooperation, for example, in peacekeeping in the Balkans and Afghanistan, where UN-authorized NATO-led operations work alongside UN peace operations. We have also worked together and collectively with other partners in support of regional and sub-regional organizations. In addition, NATO provided assets and personnel to Pakistan in support of UN disaster relief operations in 2005. Our cooperation is guided by the UN Charter, internationally recognized humanitarian principles and guidelines, and consultation with national authorities.

3. Further cooperation will significantly contribute to addressing the threats and challenges to which the international community is called upon to respond. We therefore underscore the importance of establishing a framework for consultation and dialogue and cooperation, including, as appropriate, through regular exchanges and dialogue at senior and working levels on political and operational issues. We also reaffirm our willingness to provide, within our respective mandates and capabilities, assistance to regional and sub-regional organizations, as requested and as appropriate.

4. Understanding that this framework should be flexible and evolving over time, we agree to further develop the cooperation between our organizations on issues of common interest, in, but not limited to, communication and information-sharing, including on issues pertaining to the protection of civilian populations; capacity-building, training and exercises; lessons learned, planning and support for contingencies; and operational coordination and support.

5. Our cooperation will continue to develop in a practical fashion, taking into account each Organizations specific mandate, expertise, procedures and capabilities, so as to contribute to improving international coordination in response to global challenges.
