Comparative Analysis of Cyber Diplomacy Strategies in East Asia and Southeast Asia

Thesis Abstract

The rapid proliferation of digital technologies and increasing cyber threats have elevated the significance of cyber diplomacy as a strategic tool for national security, economic stability, and international influence in both East Asia and Southeast Asia. However, despite the region's geopolitical interconnectedness and digital integration, there exists a notable divergence in the approaches, priorities, and effectiveness of cyber diplomacy strategies among countries in these subregions. This study aims to undertake a comparative analysis of cyber diplomacy strategies employed by key states in East Asia and Southeast Asia, with the objective of identifying commonalities, differences, and antecedent factors influencing their policy formulations. Employing a comparative research design framed within the constructivist and realist theoretical paradigms, the investigation explores how state interests, regional security concerns, technological capabilities, and international norms shape the cyber diplomacy strategies in these contexts. The study's population comprises policy documents, official statements, regional forums, and diplomatic initiatives from ten countries—five from East Asia (China, Japan, South Korea, Taiwan, and Mongolia) and five from Southeast Asia (Indonesia, Malaysia, Thailand, Singapore, and Vietnam). A purposive sampling method is used to select relevant documents and policy actors over a decade (2012–2022). Data collection involves a combination of content analysis of official documents and semi-structured interviews with twenty key diplomatic and cybersecurity officials across the selected countries. Quantitative data derived from content analysis will be coded and analyzed using SPSS, employing descriptive statistics, cross-tabulations, and ANOVA to identify significant differences and similarities across the regions. Additionally, thematic analysis will be conducted on interview transcripts utilizing NVivo to capture contextual nuances and interpretative insights. The research also incorporates a qualitative comparative analysis (QCA) approach to explore configurations of strategies associated with specific outcomes, such as regional stability or cyber incident mitigation. It is anticipated that the study will reveal distinct regional patterns East Asian states tend to adopt a more assertive and economically driven cyber diplomacy approach, emphasizing technological sovereignty and international norm development, while Southeast Asian countries demonstrate a more collaborative and security-focused strategy, emphasizing regional cooperation frameworks. The findings are expected to highlight how national interests, regional integration levels, and external influences shape these divergent frameworks. A notable contribution of this research is the development of a comparative framework that isolates the core drivers and constraints of cyber diplomatic efforts in emerging regional contexts. The expected findings will offer a nuanced understanding of how regional geopolitical dynamics influence cyber diplomacy behaviors and policies. It also aims to fill existing gaps in the literature concerning region-specific analyses, especially the paucity of systematic comparative studies between East and Southeast Asia. The study provides theoretical contributions by operationalizing the constructivist and realist perspectives into empirical indicators and advancing the concept of cyber diplomacy as an evolving instrument of soft and hard power. In conclusion, the research underscores the importance of contextual factors in shaping effective cyber diplomacy and suggests that regional integration, technological capacity, and normative alignment are critical to fostering resilience and cooperation in the digital domain. The study recommends enhanced regional dialogue frameworks, capacity-building initiatives, and normative collaboration as pathways toward more cohesive cyber policies. Directions for future research include longitudinal studies to assess strategy evolution and the role of non-state actors in regional cyber diplomacy. Overall, this research advances scholarly understanding and policy relevance, offering a comprehensive model for analyzing cyber diplomatic strategies across diverse geopolitical contexts.
