Governments/Sovereigns
As international counsel to sovereign states, sub-sovereigns, state-owned entities, and multilateral organizations spanning five continents, Arnold & Porter understands the interplay of law, politics, public relations, and diplomacy when complex deals arise and high-profile or high-value disputes emerge. Our premier international practice has been combining deep professional experience with expansive perspectives to handle these types of transactions and disputes since the 1960s. Backed by the recognized excellence of our corporate and finance, regulatory, litigation, international arbitration, and international trade services — and enhanced by the awareness and finesse derived from the service of some of our partners in senior positions in U.S. and foreign governments and organizations — we provide the in-depth legal, policy, and negotiation skills that clients need in delicate situations.
