In 2025, the United Nations marks its 80th anniversary. UN Day, observed annually on 24 October, commemorates the entry into force of the UN Charter in 1945 - establishing the UN as a global platform for peace, cooperation, and human rights. To celebrate this milestone, the UN in Mongolia, in partnership with the Ministry of Foreign Affairs, will host UN Week from 20 - 24 October, featuring events that reflect on eight decades of global progress and inspire future commitment.
