Arnold & Porter's Public International Law practice is led by a team of former senior US government and international organization officials with exceptional international law experience. These include former US State Department Legal Adviser John Bellinger, former Deputy Legal Adviser Samuel Witten, former Assistant Legal Adviser Jeffrey Smith (who later served as General Counsel of the Central Intelligence Agency), former Assistant Legal Adviser Paolo Di Rosa (who also heads the firm's International Arbitration practice), and former US Executive Director of the World Bank Whitney Debevoise. Our lawyers are well-known and respected by senior government officials and public international law professionals worldwide.

We advise and represent States, State entities, multinational corporations, and individuals on some of the most challenging and sensitive matters of international law and foreign affairs. The variety and depth of our senior leadership enable us to provide service to clients on innovative and complex issues of first impression. Our attorneys' extensive and high-level government experience inside the US Government makes us especially well-attuned to the legal, political, diplomatic, internal, and budgetary concerns of foreign governments, in addition to the needs of our corporate clients.

We bring to our sovereign and private sector clients deep and practical experience on topics spanning all aspects of public international law, such as foreign relations litigation in US courts; proceedings before international tribunals; treaty negotiations, ratification, and implementation; laws relating to the immunity of sovereigns and governmental agencies, instrumentalities, and officials; territorial disputes; dispute settlement proceedings (both government-to-government and investor-state); international trade and investment matters; the law and practice of international financial institutions; international criminal matters and law enforcement cooperation; and numerous other issues.
