"The United Nations Charter points the way, with its vision of people and countries living as good neighbours, defending universal values and recognizing our common future. Strengthening multilateralism means strengthening our commitment to achieving the Sustainable Development Goals and building a safer, more just world for future generations." — UN Secretary-General António Guterres

On April 24 2019, the first official International Day of Multilateralism and Diplomacy for Peace will be celebrated and the General Assembly will convene a one-day high-level plenary meeting PDF to commemorate and promote the day.

The International Day was officially approved on 12 December, 2018 through resolution A/RES/73/127. 24 April of every year is designated as the day for the international observance.

Preserving the values of multilateralism and international cooperation, which underpin the UN Charter and the 2030 Agenda for Sustainable Development, is fundamental to promote and support the three pillars of the UN - peace and security, development and human rights.

The international norms and rules-based system that have steered nations through seven decades must rise to meet the mounting challenges of protectionism and isolationism. Global issues such as climate change, geopolitical tensions, humanitarian and migratory crises are cross-cutting, implicating the values and interests of nations and necessitate collective attention and action. Technological advancement has also impacted the political and socio-economic landscape and inter-state relations.

As emphasized in the resolution, the International Day is a reaffirmation of the UN Charter and its principles of resolving disputes among countries through peaceful means. It acknowledges the use of multilateral decision-making and diplomacy in achieving peaceful resolutions to conflicts among nations.
