The United Nations Commission on International Trade Law (UNCITRAL) (French: Commission des Nations Unies pour le droit commercial international (CNUDCI)) is a subsidiary body of the U.N. General Assembly (UNGA) responsible for helping to facilitate international trade and investment. Established by the UNGA in 1966, UNCITRAL's official mandate is "to promote the progressive harmonization and unification of international trade law" through conventions, model laws, and other instruments that address key areas of commerce, from dispute resolution to the procurement and sale of goods.
