Chong Ja Ian is a nonresident scholar at Carnegie China, Carnegie’s East Asia-based research center on contemporary China, where he examines U.S.-China dynamics in Southeast Asia and the broader Asia-Pacific. Chong is also an associate professor of political science at the National University of Singapore. He received his PhD from Princeton University in 2008 and previously taught at the Hong Kong University of Science and Technology. His research covers the intersection of international and domestic politics, with a focus on the externalities of major power competition, nationalism, regional order, security, contentious politics, and state formation. He also works on U.S.-China relations, security and order in Northeast and Southeast Asia, cross-strait relations, and Taiwan’s politics.

He was a 2019-20 Harvard-Yenching Visiting Scholar, 2013 Taiwan Fellow, 2012-13 East-West Center Asia Fellow, and a 2008-9 Princeton-Harvard China and the World Fellow. Chong’s current research examines how non-leading state behavior collectively intensifies major power rivalries, paying particular attention to the U.S.-China relationship. He has concurrent projects investigating how states react to sanctions on third parties by trade partners, and the characteristics of foreign influence operations. Chong has a longstanding interest in bridging academic, policy, and public discussions regarding these topics.

Chong is the author of External Intervention and the Politics of State Formation: China, Indonesia, Thailand, 1893-1952 (Cambridge, 2012), and a recipient of the 2013 International Security Studies Section Book Award from the International Studies Association.
