On 12 February 2015, the Special Representative and the High Representative of the Union for Foreign Affairs and Security Policy, Federica Moghe rini, renewed their commitment to work together in a joint statement on ending the recruitment and use of children in armed conflict. The Special Representative addressed the European Parliament on 3 December 2014, focusing on how better to protect childre n in armed conflict.

The aim of the agreement is to further strengthen the collaboration between the two entities, with a focus on ensuring the protection of children living in conflict -affected areas in the Arab world. In particular, the agreement seeks to enhance the capacity of the League to address issues pertaining to children and armed conflict across its areas of operation. The Office of the Special Representative and the Permanent Observer Mission of the League of Arab States to the United Nations developed a workplan in which immediate and long-term activities and joint engagement are outlined. The workplan articulates practical steps required to strengthen the internal capacity of the League, with the overall objective of adopting a strategy on the protection of children affected by armed conflict. The efforts are in line with General Assembly resolution 69/9 of 11 November 2014 on cooperation between the United Nations and the League of Arab States. North Atlantic Treaty Organization 55.

With that aim, her Office participated in a workshop in April 2015 that focused on using practical field experience to create training on the issue of children and armed conflict for current and future NATO deployments. The inclusion of a children and armed conflict advisor in the Resolute Support Mission in Afghanistan is also a welcome step that will improve the capacity of NATO troops and national authorities regarding children and armed conflict issues. In the Wales Summit Declaration of 5 September 2014, NATO reaffirmed its commitment to implement Security Council resolution 1612 (2005) and further integrate the issue of children and armed conflict into the planning and conduct of its operations and missions and into its training, monitoring and reporting. 14/17 15-12221
