Warren H. Maruyama

Warren Maruyama brings a wealth of experience in government and private practice to solving complex commercial and market access problems, especially those involving Free Trade Agreement (FTA) and World Trade Organization (WTO) disputes, trade negotiations, and trade legislation.

Drawing on his high-level experience at the Office of the United States Trade Representative (USTR), the White House, and U.S. International Trade Commission, Warren helps clients take full advantage of FTA negotiations such as the Trans-Pacific Partnership (TPP), Transatlantic Trade and Investment Partnership (TTIP), and WTO and FTA rules to address market access barriers. He has been selected as an arbitrator for disputes under the U.S.-Korea and U.S.-Central America-Dominican Republic Free Trade Agreements.

He oversaw the U.S. WTO challenges to foreign trade barriers, Doha Round negotiations, and the USTR's participation in the U.S.-China Strategic Economic Dialogue and U.S.-China Joint Commission on Commerce and Trade.

Warren served on the White House policy staff from 1989-1992, helping develop President George H.W. Bush's Super 301, NAFTA, Uruguay Round, and Steel Trade Liberalization initiatives.
