The International Day of Multilateralism and Diplomacy for Peace was established on 12 December, 2018 through resolution A/RES/73/127.
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.
