The United Nations marked the 80th anniversary of the signing of its founding Charter on June 26, 2025. The Charter, signed by representatives of 50 nations in San Francisco in 1945, established the UN's foundational principles of peace, international cooperation, human rights, and multilateralism. As the organization commemorates this milestone, UN Secretary-General Antonio Guterres warned that the Charter's principles are under unprecedented assault, emphasizing that the Charter is not an "a la carte menu" to be selectively applied. He called for renewed commitment to uphold the Charter as the bedrock of international relations and global governance. Various member states, including China, Germany, France, and Armenia, reaffirmed their dedication to the Charter's ideals and stressed the importance of true multilateralism and respect for international law. China, as the first country to sign the Charter, highlighted its ongoing commitment to the UN-centered international system. Meanwhile, global reflections on the UN's role acknowledged challenges such as declining global influence, international tensions, and violations of the Charter's principles. Despite these difficulties, the UN continues to be recognized for its efforts in peacekeeping, diplomacy, and addressing global issues such as poverty, hunger, and human rights. The anniversary was marked by calls from UN leaders and member states to reinvigorate the organization with greater impact, effectiveness, and accountability to meet contemporary global challenges.
