U.S. Ambassador
Kingdom of Thailand
Ambassador Michael George DeSombre was nominated by President Trump on July 17, 2019 and confirmed by the United States Senate on January 8, 2020 as U.S. Ambassador to the Kingdom of Thailand. Ambassador DeSombre was a partner in the global law firm of Sullivan and Cromwell from 2004 to 2019, where he led their mergers and acquisition practice in Asia. Ambassador DeSombre has over two decades of experience representing and negotiating on behalf of American and international clients in large scale investment and economic development projects in Asia. Ambassador DeSombre has energized the U.S.-Thai partnership by frequently engaging with civilian and military officials to further solidify our long-standing alliance. As the first U.S. Ambassador to the Kingdom of Thailand to come from the private sector, he has prioritized strengthening the U.S. – Thai economic partnership. He has built bridges between U.S. firms and the Thai government, established a new advisory council of prominent U.S. business leaders in Thailand, met with all levels of the Royal Thai Government to advise on concrete ways our economies can prosper together, and oversaw the creation of Embassy “Deal Teams” that have deepened economic ties between the United States and Thailand. Ambassador DeSombre steered the Mission’s cooperation with the Royal Thai Government on the COVID response, expanding upon decades of cutting-edge health cooperation between our two countries. He is committed to the importance of religious freedom and other fundamental rights, and has worked with Thailand’s religious leaders from all faiths, and government officials, to ensure that support for these freedoms continues to be an area where the United States and Thailand lead by example. He is also steadfast in his commitment to ensure that smaller countries, such as those in the Mekong region, have choices when it comes to making decisions regarding their sovereignty and access to natural resources. Ambassador DeSombre has penned numerous op-eds for publication in the Thai press on a broad range of issues, including the US-Thai economic relationship, bilateral law enforcement cooperation, and protection of the Mekong and the people who rely on it. Ambassador DeSombre graduated from Stanford University with a B.A. in Quantitative Economics and an M.A. in East Asian Studies and received his J.D. from Harvard Law School. He is married with four children.
