International Day of Multilateralism and Diplomacy for Peace, established by the United Nations in 2018, is dedicated to promoting the values of multilateralism and international cooperation, which are fundamental principles of the UN Charter. This day serves to emphasize the importance of diplomacy as a means of resolving conflicts, fostering peace, and addressing global challenges collectively. It also aims to support and advance the three pillars of the United Nations—peace and security, development, and human rights—by promoting dialogue, negotiation, and collaboration among nations. The International Day of Multilateralism and Diplomacy for Peace underscores the critical role of multilateral institutions in promoting stability, prosperity, and respect for human rights around the world.
