United Nations Commission on International Trade Law
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.
UNCITRAL carries out its work at annual sessions held alternately in New York City and Vienna, where it is headquartered. Provided by Wikipedia
