East Asian Security and Political Economy with a focus on China, Japan, and Korea


Yeajin Yoon is a 2018-2019 MacArthur Nuclear Security Pre-doctoral Fellow at CISAC and a doctoral candidate in the Blavatnik School of Government at the University of Oxford. Her dissertation examines the evolution of trilateral cooperation among the most militarily and economically dominant states in Northeast Asia, namely, China, Japan and the Republic of Korea, and considers when and how their relations become implicated in the North Korean nuclear crisis.

Prior to entering academia, Yeajin travelled extensively across Asia and worked with national governments, international organisations, and NGOs in the region. She led the development of the inaugural issue of the 'Oxford Government Review’ and helped facilitate a Track II dialogue on wartime history issues in Asia at Stanford University. Previously, she worked as a founding member of the Trilateral Cooperation Secretariat, the official intergovernmental organisation for China, Japan, and the Republic of Korea and managed a development fund focused on the ASEAN region at the Korean Foreign Ministry.

Yeajin received a Bachelor of Arts in Political Science with Honors from Stanford University and a Master of Public Policy degree from Oxford University.
