Relations with the United Nations

  • Last updated: 21 Jun. 2016 10:30

NATO and the United Nations (UN) share a commitment to maintaining international peace and security. The two organisations have been cooperating in this area since the early 1990s, in support of peace-support and crisis-management operations. The complexity of today’s security challenges has required a broader dialogue between NATO and the UN. This has led to reinforced cooperation and liaison arrangements between the staff of the two organisations, as well as UN specialised agencies.

  • NATO’s 2010 Strategic Concept commits the Alliance to preventing crises, managing conflicts and stabilising post-conflict situations, including by working more closely with NATO’s international partners, most importantly the UN and the European Union (EU).
  • UN Security Council Resolutions have provided the mandate for NATO’s operations in the Western Balkans, Afghanistan and Libya. They have also provided the framework for NATO’s training mission in Iraq.
  • NATO has also provided support to UN-sponsored operations, including logistical assistance to the African Union’s UN-endorsed peacekeeping operations in Darfur, Sudan, and in Somalia; support for UN disaster-relief operations in Pakistan, following the massive earthquake in 2005; and escorting merchant ships carrying World Food Programme humanitarian supplies off the coast of Somalia.
  • Practical cooperation between NATO and the UN  extends beyond operations to include: crisis assessment and management, civil-military cooperation, training and education, tackling corruption in the defence sector, mine action, mitigating the threat posed by improvised explosive devices, civilian capabilities, promoting the role of women in peace and security, the protection of civilians, including children, in armed conflict, combating sexual and gender-based violence, arms control and non-proliferation, and the fight against terrorism.
  • At the 2015 Leaders’ Summit on Peacekeeping, held on the margins of the 70th UN General Assembly, NATO also pledged enhanced support to the UN in the area of peace operations.
  • In 2010, following the signing of the 2008 UN-NATO declaration on cooperation, NATO reinforced its liaison arrangements by establishing the post of NATO Civilian Liaison Officer to the United Nations, in addition to that of a Military Liaison Officer, established in 1999.
  • Enhanced cooperation with the UN – and other international actors such as the EU and the Organization for Security and Co-operation in Europe – is an integral part of NATO’s contribution to a “Comprehensive Approach” to crisis management and operations.

  • Framework for cooperation

    In September 2008, building on the experience of over a decade of working together, the Secretaries General of the two organisations agreed to establish a framework for expanded consultation and cooperation.

    Since the signing of the 2008 framework, cooperation has continued to develop in a practical way, taking into account each organisation’s specific mandate, expertise, procedures and capabilities. Regular exchanges and dialogue at senior and working levels on political and operational issues have become a standard feature of the inter-institutional relationship. NATO’s Secretary General reports regularly to the UN Secretary-General on progress in UN-mandated NATO-led operations and on other key decisions of the North Atlantic Council, including in the area of crisis management and in the fight against terrorism. The UN is frequently invited to attend NATO ministerial meetings and summits; the NATO Secretary General participates in the UN General Assembly; and staff level meetings, covering the broad range of cooperation and dialogue, take place on an annual basis between the secretariats of NATO and the UN.

  • Key areas of cooperation

    Peace operations

    NATO’s unique capabilities and experience can be a valuable source of support to the UN, whose peacekeepers operate in increasingly challenging and dangerous environments. NATO and UN staffs have worked to build practical cooperation in this domain.

    At the 2015 Leaders’ Summit on Peacekeeping, the NATO Secretary General pledged to enhance support to the UN, in particular in the areas of countering improvised explosive devices, training and preparedness, supporting the UN’s efforts to deploy more rapidly and working more closely on capacity building in countries at risk, both with the UN Nations and the EU. As the UN reforms its approach to peace operations, NATO will continue to look for where its support can make a difference.


    The UN Global Counter-Terrorism Strategy, international conventions and protocols against terrorism, together with relevant UN Security Council Resolutions provide the framework for NATO’s efforts to combat terrorism. NATO works closely at staff and committee level with the UN Counter-Terrorism Committee (UN CTC) and its Executive Directorate, as well as with the Counter-Terrorism Implementation Task Force and many of its component organisations. The Terrorism Prevention Branch of the UN Organisation for Drugs and Crime is also an important partner for NATO.  


    NATO contributes to the work of the UN Security Council Committee established following the adoption of UNSCR 1540 (2004), which addresses the threat to international peace and security posed by the proliferation of nuclear, chemical and biological weapons and their means of delivery. In this context, since 2004 the Alliance has been organising a string of international non-proliferation conferences and  seminars with the active participation of partner countries and international organisations, latest in Ljubljana, Slovenia on 9 and 10 May 2016.

    NATO has also addressed the implementation of UNSCR 1540 at regional and sub-regional levels, including through its Science for Peace and Security Programme, and will continue to address the need for assistance of partner countries upon request.

    Women, Peace and Security

    NATO remains committed to the full implementation of UNSCR 1325 on Women, Peace and Security and related Resolutions, which aim to protect and promote women’s rights, role and participation in preventing and ending conflict.  In line with the policy developed by NATO Allies together with partners in the Euro-Atlantic Partnership Council (EAPC), significant progress has been made in implementing the goals set out in these Resolutions. 

    In this regard, NATO has endorsed a Strategic Report on mainstreaming UNSCR 1325 and related Resolutions across NATO’s core activities: collective defence; crisis management and operations; and cooperative security.  An updated NATO Action Plan for the Implementation of the UNSCR 1325/EAPC Policy on Women, Peace and Security was also agreed.

    In October 2015, NATO’s Deputy Secretary General participated in the UN Security Council Open Debate on Women, Peace and Security, and pledged to do more in this area, including sharing best practices and lessons learned on increasing female participation at decision-making levels with Allies and partners; encouraging Allies to submit female candidates for NATO’s most senior decision-making positions; strengthening partnerships with international organisations like the UN, OSCE, the EU and the African Union on gender equality, as well as institutionalising the engagement of civil society in the development, execution and monitoring of the NATO/EAPC Action Plan on Women, Peace, and Security. 

    NATO also committed to financing evidence-based research aimed at understanding the role of gender in preventing and countering violent extremism, which complimented the adoption in 2015 of UNSCR 2242 at the 15th anniversary commemoration of UNSCR 1325.

    Protecting children in armed conflict

    NATO is committed to the implementation of UNSCR 1612 and related Resolutions on the protection of children affected by armed conflict.  At the 2014 NATO Summit in Wales, NATO leaders decided more could be done to ensure the Alliance is sufficiently prepared whenever and wherever the issue of Children and Armed Conflict is likely to be encountered. The result was the NATO policy document "The Protection of Children in Armed Conflict - Way forward".

    Prepared in cooperation with the UN, the policy aims to deepen the implementation of the UNSCR 1612 into NATO operations and missions. These efforts include training the Alliance's deployed troops to recognise, monitor and report violations against children and to incorporate child protection issues into NATO exercise scenarios. When it is invited to train local forces, NATO also emphasises the importance of protecting children in armed conflict. NATO also recently appointed a Children and Armed Conflict Advisor as part of the Resolute Support Mission in Afghanistan.

    Small arms and light weapons 

    NATO supports the implementation of the UN Programme of Action to Prevent, Combat and Eradicate the Illicit Trade in Small Arms and Light Weapons (SALW), adopted in July 2001 by nearly 150 countries, including all NATO member states. The Alliance also participates in UN experts’ meetings and review conferences. The NATO/EAPC Ad Hoc Working Group on SALW and Mine Action as well as the Trust Fund mechanism were established in 1999 to support partner countries in implementing provisions of the Ottawa Convention (also known as the Antipersonnel Mine Ban Convention). Moreover, NATO supports nations in implementing the Arms Trade Treaty that entered into force in December 2014 through training and application of standards.

    NATO has also worked closely with UN agencies to develop international standards for ammunition life-cycle management, such as the International Ammunition Technical Guidelines. The Alliance also strives to support regional and sub-regional efforts with the UN and partners beyond the EAPC area in managing SALW, ammunition, explosive remnants of war. In this context, NATO developed some capacities through its Science for Peace and Security Programme.

    Disaster relief

    NATO also cooperates with the UN in support of disaster-relief operations. Through the Euro-Atlantic Disaster Response Coordination Centre (EADRCC), NATO coordinates consequence-management efforts with UN and other bodies and shares information on disaster assistance. All the EADRCC’s tasks are performed in close cooperation with the UN Office for the Coordination of Humanitarian Affairs (UN OCHA), which retains the primary role in the coordination of international disaster-relief operations.

    The EADRCC is a regional coordination mechanism, supporting and complementing the UN efforts. In the case of a disaster requiring international assistance, it is up to individual NATO member and partner countries to decide whether to provide assistance, based on information received from the EADRCC.

  • Evolution of NATO-UN cooperation in the field

    Working relations between the United Nations and the Alliance were limited during the Cold War. This changed in 1992, against the background of growing conflict in the Western Balkans, where their respective roles in crisis management led to an intensification of practical cooperation in the field.

    Bringing peace to the former Yugoslavia

    In July 1992, NATO ships belonging to the Alliance's Standing Naval Force Mediterranean, assisted by NATO maritime patrol aircraft, began monitoring operations in the Adriatic in support of a UN arms embargo against all republics of the former Yugoslavia. A few months later, in November 1992, NATO and the Western European Union (WEU) began enforcement operations in support of UN Security Council Resolutions aimed at preventing the escalation of the conflict.

    The readiness of the Alliance to support peacekeeping operations under the authority of the UN Security Council was formally stated by NATO foreign ministers in December 1992. A number of measures were subsequently taken, including joint maritime operations under the authority of the NATO and WEU Councils: NATO air operations; close air support for the United Nations Protection Force (UNPROFOR); air strikes to protect UN "Safe Areas"; and contingency planning for other options which the UN might take.

    Following the signature of the General Framework Agreement for Peace in Bosnia and Herzegovina (the Dayton Agreement) on 14 December 1995, NATO was given a mandate by the United Nations, on the basis of UN Security Council Resolution 1031, to implement the military aspects of the peace agreement. NATO’s first peacekeeping operation – the Implementation Force (IFOR) – began operations in Bosnia and Herzegovina to fulfil this mandate in December 1995. One year later, it was replaced by the NATO-led Stabilisation Force (SFOR). Throughout their mandates both multinational forces worked closely with other international organisations and humanitarian agencies on the ground, including UN agencies such as the UN High Commissioner for Refugees (UNHCR) and the UN International Police Task Force (IPTF).

    From the onset of the conflict in Kosovo in 1998 and throughout the crisis, close contacts were maintained between the UN Secretary-General and NATO’s Secretary General. Actions were taken by the Alliance in support of UN Security Council Resolutions both during and after the conflict. The Kosovo Force (KFOR) was deployed on the basis of UN Security Council Resolution 1244 of 12 June 1999 to provide an international security presence as the prerequisite for peace and reconstruction of Kosovo. Throughout its deployment, KFOR has worked closely with the UN Interim Administration Mission in Kosovo (UNMIK) as well as with other international and local stakeholders.

    In 2000 and 2001, NATO and the United Nations also cooperated successfully in containing major ethnic discord in southern Serbia and preventing a full-blown civil war in the former Yugoslav Republic of Macedonia¹.


    Cooperation between NATO and the UN is playing a key role in Afghanistan. The Alliance formally took over the International Security Assistance Force (ISAF), a UN-mandated force, in August 2003. Originally tasked with helping to provide security in and around Kabul, ISAF was subsequently authorised by a series of UN Security Council Resolutions to expand its presence into other regions of the country to extend the authority of the central government and to facilitate development and reconstruction.

    NATO and ISAF worked closely with the United Nations Assistance Mission in Afghanistan (UNAMA) and other international actors that are supporting governance, reconstruction and development. The close cooperation took place in various settings, in Afghanistan as well as in UN and NATO capitals. It included co-membership of the Joint Coordination and Monitoring Board (JCMB) overseeing the implementation of the internationally endorsed Afghanistan Compact, co-chairmanship together with the Afghan Government of the Executive Steering Committee for Provincial Reconstruction Teams, and other joint Afghan-international community bodies.

    NATO and the UN continue consulting closely on their respective postures in Afghanistan. NATO is keeping the UN well informed on the Resolute Support Mission.


    Under the terms of UN Security Council Resolution 1546 and at the request of the Iraqi Interim Government, NATO provided assistance in training and equipping Iraqi security forces through the NATO Training Mission-Iraq (NTM-I) from 2004 to end 2011.

    Supporting African Union missions

    In June 2005, following a request from the African Union (AU) and in close coordination with the United Nations and the European Union, NATO agreed to support the AU’s Mission in Sudan (AMIS), which is trying to end the continuing violence in the Darfur region. NATO assisted by airlifting peacekeepers from African troop-contributing countries to the region and also helped train AU troops in how to run a multinational military headquarters and how to manage intelligence.

    Following a request from the AU in 2007, NATO accepted to assist the AU Mission in Somalia (AMISOM) by providing airlift support to AU member states willing to deploy on this mission. NATO is also providing capacity-building assistance for the AU via a Senior Military Liaison Office in Addis Ababa, Ethiopia.

    Deterring piracy

    In October 2008, NATO agreed to a request from the UN Secretary-General to deploy ships off the coast of Somalia to deter piracy and escort merchant ships carrying World Food Programme cargo.


    On 27 March 2011, NATO Allies decided to take on the whole military operation in Libya under United Nations Security Council Resolution 1973. The purpose of Operation Unified Protector was to protect civilians and civilian-populated areas under threat of attack. NATO implemented all military aspects of the UN Security Council Resolution.  Allies moved swiftly and decisively to enforce the arms embargo and no-fly zone called for in the resolution, and to take further measures to protect civilians and civilian-populated areas from attack. Operation Unified Protector was concluded on 31 October 2011.

  • The North Atlantic Treaty and the UN Charter

    The Charter of the United Nations, signed in San Francisco on 26 June 1945, establishes the overall responsibility of the UN Security Council for international peace and security. NATO’s North Atlantic Treaty signed four years later – on 4 April 1949 – makes clear that the UN Charter is the framework within which the Alliance operates. In the Treaty, Allies reaffirm their faith in the purposes and principles of the Charter and commit themselves to the peaceful resolution of conflicts. They also commit themselves to the principle of collective defence, in line with Article 51 of the UN Charter, which establishes the inherent right of individual or collective defence of all UN member countries. Collective defence is central to NATO’s founding treaty and commits Allies to protecting each other, setting a spirit of solidarity within the Alliance.
