The United Nations Commission on International Trade Law is a United Nations agency based in Vienna, specializing in the development of model legal instruments and conventions in the area of international trade law. Most notable success is perhaps the so-called 1980 Vienna Convention whose official name is The Convention of the International Sale of Goods (CISG). Also, UNICITRAL Rules for Arbitration, which provide a procedural framework for international commercial arbitration but which, unlike the ICC rules, do not provide direct administrative supervision of arbitral process.
