Rexon Ryu


Rexon Y. Ryu is a Partner of The Asia Group. Drawing on two decades of experience working in global diplomacy, national policymaking, and executive leadership, Rexon offers companies in-depth strategic and political insight across the Asia-Pacific region and a nuanced ability to translate geopolitical and economic trends, events, and relationships into results-oriented business development campaigns, advocacy, and government relations strategy. Having served three Presidents at the highest levels of the U.S. government since first entering public service in 1994, Rexon has worked extensively with both Republicans and Democrats, navigating political complexities to achieve actionable results. At The Asia Group, Rexon supports clients in strategic sectors through market entry and expansion strategies, efforts to address political-level policy decisions that carry market implications, and strategic communications outreach.

At the White House, the State Department and the Pentagon, Rexon has worked on the major foreign policy and national security challenges facing the United States, notably in Asia and the Middle East. Through his work, Rexon has helped to expand strategic alliances and relationships, project U.S. influence globally, employ U.S. power against adversaries, prevent the proliferation of weapons of mass destruction, and plan for future challenges and opportunities.

Rexon most recently served as Chief of Staff to Secretary of Defense, and former Republican Senator from Nebraska, Chuck Hagel. Rexon helped lead and manage the Department of Defense, the world’s largest organization of nearly three million personnel with a budget exceeding $500 billion. He worked closely with the Secretary and the Department’s civilian and military leaders on all priority issues, including combatting terrorism in the Middle East, the strategic rebalance to Asia, accomplishing far-reaching institutional reform, and advancing the U.S. military’s innovation and technology advantage.

Rexon also worked on the President’s National Security Council staff from 2009 to 2011, during which time he was focused on nonproliferation, Iran, and North Korea. In this capacity, he served on the U.S. delegation for several rounds of multilateral negotiations with Iran. Rexon served as the Deputy to the U.S. Ambassador to the United Nations from 2011 to 2014, where he directed the Ambassador’s Washington office under both Susan Rice and Samantha Power. In this position, Rexon played a direct role in formulating, deciding, and implementing nearly all consequential national security decisions as a standing member of the National Security Council’s Deputies Committee.

Rexon served for four years in the U.S. Senate as the foreign policy adviser for then-Senator Hagel. He began his public service career at the State Department, where he served abroad in both Cairo and Jerusalem, and as special assistant to then-Deputy Secretary of State Richard Armitage.

Rexon also holds the following positions: nonresident senior associate at the Carnegie Endowment for International Peace, member of the International Advisory Board for the Atlantic Council’s Rafik Hariri Center for the Middle East, and member of the Board of Trustees for HALO USA. Rexon is a life member of the Council on Foreign Relations. He holds a Master of Public Policy from Princeton University and a Bachelor of Arts in Political Science and Government from the University of California, Berkeley.

Rexon lives in Washington, DC with his wife and two daughters.
