Recognized as a leader in international trade law and policy, Warren Maruyama’s practice focuses on advising clients on U.S. trade law and negotiations, including the Trump Administration's Section 301, 201, and 232 tariffs, U.S.-Mexico-Canada Agreement (USMCA), WTO disputes, IEEPA, Section 301 tariff exclusions, and FTA negotiations. He has advised U.S. and multinational firms on how to use U.S. trade law, WTO disputes, and FTA and bilateral negotiations to address market access barriers.

Warren served as General Counsel of the Office of the United States Trade Representative (USTR) for President George W. Bush from 2007-2009, Associate Director of the White House Policy Development staff for President George H.W. Bush (1989-1992), and USTR Associate General Counsel (1983-1989). He started his career in the federal government as a staff lawyer at the U.S. International Trade Commission.

Warren is recognized for his strategic vision, creativity, and innovative and effective solutions to trade challenges. As USTR General Counsel, he oversaw the filing of 10 U.S. WTO and bilateral challenges to foreign trade barriers, including 5 cases against China; helped lead Doha, Uruguay Round, and FTA negotiations; supervised the U.S. Section 301 carousel retaliation list in the WTO Beef-Hormones dispute; and oversaw USTR's participation in the U.S.-China SED and JCCT Cabinet-level Dialogues. He served as one of USTR’s lead negotiators for the "May 10" agreement between the Bush 43 Administration and House Democratic Leadership that resolved a decade-long impasse over the role of labor and environmental rules in U.S. FTAs, and cleared the way for Congressional approval of the Peru, Korea, Colombia, and Panama FTAs. As a White House staffer, he helped design President George H.W. Bush’s Steel Trade Liberalization, Super 301, and Enterprise for the Americas Initiatives, and drafted the President’s announcement of the successful conclusion of NAFTA negotiations.
