Ambassador Joseph Yun is senior advisor to the Asia Program at USIP.  As former US Special Representative for North Korea Policy, he is recognized as one of the nation’s leading experts on relations with North Korea, as well as on broader US-East Asian policy. His 33-year diplomatic career has been marked by his commitment to face-to-face engagement as the best avenue for resolving conflict and advancing cross-border cooperation.

During his tenure, Ambassador Yun hosted two visits to Malaysia by President Obama—the first by any US President since 1966—resulting in the signing of the US-Malaysian Comprehensive Partnership Agreement, pledging closer cooperation on security, trade, education, technology, energy, the environment, and  people-to-people ties.

As Principal Deputy Assistant Secretary for East Asian and Pacific Affairs (2011-2013), he led efforts to normalize diplomatic relations with Myanmar, traveling to Rangoon as the first US-based government official to meet with Burmese democracy leader Aung San Suu Kyi following her release from house arrest.
