Framing ASEAN in the Platform Age: Media Infrastructures and Geopolitical Narratives in East Asia

This study examines how Association of Southeast Asian Nations (ASEAN) is framed in Chinese, Japanese, and South Korean English-language mainstream media during four high-salience geopolitical events (2023–2025). Methodologically, it employs a qualitative comparative framing and discourse analysis of 28 systematically selected news articles from leading outlets in each media system, coded using Entman’s four framing functions (problem definition, causal attribution, moral evaluation, and treatment recommendation) and supplemented by representational logics and explicitly stated platform-governance indicators. Drawing on framing theory, representation, platform governance, and critical geopolitics, the analysis finds that ASEAN is portrayed not as an autonomous actor but as a flexible signifier within nationally inflected narratives. Chinese media emphasize regional cooperation and developmental connectivity, Japanese outlets foreground liberal-normative order and security alignment, and South Korean coverage prioritizes technocratic and pragmatic partnership. The study argues that ASEAN’s mediated visibility is shaped by recurring editorial framing patterns and, where explicitly invoked, by infrastructural and platform-related cues, revealing ongoing narrative contestation over regional power and legitimacy in East Asia.
