Among the greatest achievements of the United Nations is the development of a body of international law, which is essential for promoting economic and social development, as well as advancing international peace and security. International law is established through conventions, treaties, and standards. Many of the treaties established by the United Nations form the foundation of the laws governing relations between states. Although the UN’s work in this area often does not receive attention, it impacts the lives of people everywhere on a daily basis.

The United Nations Charter specifically calls upon the organization to assist in the peaceful settlement of international disputes, including arbitration and judicial settlement (Article 33), and to promote the progressive development and codification of international law (Article 13).

Over the years, more than 500 multilateral treaties have been deposited with the United Nations Secretary-General. Many other treaties are deposited with governments or other entities. These treaties cover a wide range of topics, including human rights, disarmament, and environmental protection.
