A/HRC/38/39 South-East Asia organized by the Asia Centre in Bangkok; an ASEAN conference on the prevention of violent extremism in Manila; an ICRC conference on armed conflict in urban settings in Geneva; and a panel of the Geneva Academy on gang violence, also in Geneva. Country visits conducted by the Special Rapporteur 11. In accordance with her mandate, the Special Rapporteur has consistently engaged with States and has sought a constructive and transparent dialogue with them. She thanks the many States that she has engaged with or visited for their cooperation. Since her previous report to the Human Rights Council, the Special Rapporteur has conducted official visits to the following countries: El Salvador (from 14 to 18 August, 2017, see A/HRC/38/39/Add.1); Libya (from 25 to 31 January 2018, see A/HRC/38/39/Add.2) and Niger (from 19 to 24 March 2018, see A/HRC/38/39/Add.3). 12. In addition, the Special Rapporteur also undertook working visits to Guatemala (19– 22 August 2017), Mexico (23–25 August 2017), Honduras (25–28 October 2017) and Colombia (26 February–1 March 2018). In particular, the visit to Honduras was linked to the Special Rapporteur’s participation in a regional conference on the Comprehensive Regional Protection and Solutions Framework in San Pedro Sula, as a follow-up to the New York Declaration for Refugees and Migrants, looking at the integration of internal displacement issues into that process. In addition, she held meetings with relevant stakeholders to look at the progress made on the recommendations resulting from the previous official mission of the mandate holder to Honduras in 2015. Regarding her visit to Colombia, the Special Rapporteur was part of a special procedures delegation taking part in the 167th session of the Inter-American Commission on Human Rights. She took part in several events, most importantly a public hearing on internal displacement in the Americas. III. Twentieth anniversary of the Guiding Principles on Internal Displacement: an agenda for strategic and joint action 13. The Guiding Principles on Internal Displacement, presented to the Commission on Human Rights in 1998, constitute the key international standard on internal displacement worldwide. They provide a definition of an internally displaced person and set out their rights to be protected and assisted before and during displacement and in their search for durable solutions following displacement. They give national authorities the primary responsibility for protecting internally displaced persons and clarify key principles relating to humanitarian assistance by international and non-governmental bodies. The Guiding Principles are highly authoritative, as they restate the rights of internally displaced persons, as enshrined in international human rights and humanitarian law, and have been recognized as an important framework for the protection of and assistance to internally displaced persons. The recognition afforded by Heads of State and Government in the 2005 World Summit outcome (General Assembly resolution 60/1) was subsequently confirmed by the General Assembly on various occasions. 14. In 2018 the twentieth anniversary of the Guiding Principles will be marked. That is an occasion to raise awareness of this global standard and of the plight of internally displaced persons and to reflect on both the positive progress made and the challenges that remain and are emerging. The anniversary is also a unique opportunity to forge a stronger commitment for more strategic, concrete and joined-up action in order to more robustly and effectively prevent internal displacement, enhance protection for internally displaced persons and support durable solutions for them. 15. The Special Rapporteur consulted numerous partners at the national, regional and international levels to seek their views, in particular on what needs to be done to further promote implementation of the Guiding Principles. Her consultations with partners resulted in expressions of interest to work more strategically and collaboratively on the phenomenon of internal displacement in 2018 and beyond. It was therefore agreed that a “GP20” plan of action would be developed in order to galvanize and support multi-stakeholder action around the overarching goal of reducing internal displacement in line with the Guiding 5
