Korean medical personnel migrated across the globe since 1964, including Africa. However, analyses of the transnational nature of Korean medicine have largely focused on the influence of Korea as a recipient, particularly the United States. This study attempts to understand the formation of Korean medicine in a wider geographical space, beyond the entrenched dichotomy of donor and recipient countries, which has often been centered on the United States or Japan. This paper examines how the diplomatic competition between North and South Korea unfolded in the geopolitical context of the Cold War and how medicine was mobilized to achieve its goals. In the 1960s, medical diplomacy was effective in establishing diplomatic relations and gaining the cooperation of recipient ‘Third World’ countries. In the 1970s, however, South Korea's episodic medical aid was no longer well-received in the face of aggressive North Korean aid, and South Korean medical missions became more of an ‘export’ rather than ‘cooperation’.
