Matthew J. Thomas


Matthew J. Thomas has more than 25 years of experience in international trade, transport and maritime regulation, and government affairs, representing leading energy and commodities companies, shipowners, governments, insurers, investors, ports, shipyards, and marine terminal operators.

Matt works extensively in the areas of international trade sanctions, export controls, and related anti-money laundering measures. He has represented several global companies targeted for U.S. sanctions, reaching successful resolutions with the Departments of State and Treasury (“OFAC”). He has aided numerous clients around the world on sanctions and export control compliance planning, investigations, and transactional due diligence, with particular focus on the energy, commodities, maritime, transport, and services sectors.

In addition, Matt has extensive experience in the maritime, logistics, and container shipping sector. He has represented leading carriers, terminals, and logistics providers in regulatory proceedings before the Federal Maritime Commission (“FMC”), where he formerly served as the Assistant General Counsel for International Affairs. He represents marine terminal operators in complex joint venture arrangements and is experienced in global container operators’ merger and integration projects.

He also counsels private companies and foreign governments on matters of international law and diplomatic strategy, particularly in defending national sovereignty or combating international trade barriers. During his government tenure, he was responsible for the FMC’s relations with foreign governments and multilateral bodies, such as the European Union, World Trade Organization, and Organization for Economic Co-operation and Development.

Matt works with leading maritime and offshore energy clients on a broad range of compliance issues, including environmental, safety, citizenship, and “Jones Act” coastwise compliance. He has represented leading energy companies in key Jones Act rulings and investigations that have shaped domestic petroleum trade, and structured complex Jones Act compliance ownership structures.

Throughout his career, Matt has built strong relationships with U.S. government officials, trade associations, and the local legal and lobbying community. He guides international businesses in their dealings with the Departments of State, Treasury, Commerce, Justice, and Transportation, as well as independent regulatory agencies and Congress. In addition to his professional experience in maritime and international trade, Matt has also served as a federal lobbyist and led successful lobbying efforts on the behalf of local governments, advising on federal affairs and managing relations with congressional offices.

Matt’s broad and diverse Washington career has given him unique skills in legal and regulatory strategy and project management, including the design and execution of hybrid legal and government relations efforts to shape policy and achieve client objectives.

Matt wrote the United States chapter for Ports and Terminals (3rd Ed.), a global compendium of port law that was published in 2018 by Getting The Deal Through.
