Major studies of American foreign relations treat US failures in Vietnam as the end of both a short-lived American empire and western imperialism in Southeast Asia. Ngoei argues that Vietnam was an exception to the region’s overall pro-US trajectory after 1945, that British neo-colonialism and Southeast Asian anticommunism melded with pre-existing local antipathy toward China and the Chinese diaspora to usher the region from formal colonialism to US hegemony. By the 1970s, Southeast Asia’s anti-communist nationalists had established, with US support, a geostrategic arc of states that contained Vietnam and China. 

Wen-Qing Ngoei is assistant professor of history at Nanyang Technological University. He completed his PhD at Northwestern University and did postdoctoral stints at Northwestern and Yale University. Ngoei’s book, Arc of Containment: Britain, the United States, and Anticommunism in Southeast Asia (Cornell UP, May 2019), argues that British decolonization intertwined with Southeast Asian anticommunism to shape US policy in the wider region. He has published in Diplomatic History (2017) and his prize-winning essay on the domino theory appears in the Journal of American-East Asian Relations (2014).
