In the United Nations Global Counter-Terrorism Strategy's subsequent reviews, the General Assembly has recognized the important role of the United Nations system in promoting coordination and coherence in the implementation of the Strategy at the national, regional and international levels and in providing assistance to Member States, where requested.

The United Nations Secretariat, agencies, funds and programmes, and affiliated organizations contribute to the implementation of the Strategy both through their individual mandates and through their membership in the Counter-Terrorism Implementation Task Force (CTITF). There are currently 38 entities members of the Task Force.

The United Nations Counter-Terrorism Centre (UNCCT) was established in 2011 within the CTITF Office to assist in meeting the capacity-building needs of Member States and to strengthen United Nations' counter-terrorism expertise.

In order to achieve greater unity of purpose and strengthen coordination and coherence more broadly within the United Nations system on counter-terrorism, the CTITF was established within the Department of Political Affairs of the Secretariat under the chairmanship of the Under-Secretary-General for Political Affairs.

The Secretary-General has appointed the Under-Secretary-General for Political Affairs Chair of the CTITF and Executive Director of the UNCCT, to help ensuring that the Task Force has a global impact through its projects and contributes to the balanced implementation of all four pillars of the Strategy.  It also aims at improving the interface between the Department of Political Affairs, relevant entities of the Task Force and special political missions, thus ensuring that the United Nations response on peace and security issues, including on countering terrorism, is inclusive and integrated with its activities to promote social and economic development.

This approach is in line with the Secretary-General’s vision of the United Nations delivering as one across all areas of its work.
