This study examines the association of exposure to South Korean media with North Koreans’ attitudes on capitalism, individualism, South Korea, and their own regime (North Korean media and supreme leader). Although Hallyu (Korean Wave) content is present in North Korea, its effects remain understudied. Using survey data from 1,241 North Korean defectors (2011-2020), the study finds that exposure to South Korean media is positively associated with favorable views of capitalism, individualism, and South Korea, and with lower trust in North Korean media and leadership. Effects vary by region, underscoring the complex influence of this mediated cultural contact. By showing how media exposure shapes attitudes under conditions of severe information control, the study contributes to broader peace studies debates on communication, reconciliation, and social change.
