In December 2018, the UN General Assembly adopted resolution 73/127, designating April 24 as the International Day of Multilateralism and Diplomacy for Peace, reaffirming the principles of the UN Charter based on international cooperation and the peaceful resolution of disputes. The date marks the anniversary of the opening of the 1945 San Francisco Conference, which led to the founding of the United Nations.
The day reminds the international community that major global challenges — from armed conflict to climate change, poverty, and pandemics — cannot be addressed in isolation from cooperation between nations, and that diplomatic dialogue and multilateral action remain the most effective tools for achieving sustainable peace and protecting the rules-based international order.
The United Nations and diplomatic missions worldwide mark the day with seminars and discussions on the importance of multilateral diplomacy, along with educational events introducing young people to the mechanisms of international diplomacy.
