Comparative Analysis of Post-Cold War Regional Powers in Africa and Asia

Thesis Abstract

This study addresses the problem of understanding how post-Cold War regional powers in Africa and Asia have redefined regional order, power projection, and strategic influence amid multipolar shifts, domestic developmental imperatives, and evolving global governance. It contends that while both regions exhibit rising powers, the determinants, mechanisms, and outcomes of regional influence diverge due to distinct historical trajectories, governance models, and regional security architectures, necessitating a comparative, cross-regional analysis to illuminate patterns of influence, competition, and co-operation. The aim is to systematically assess the drivers, modalities, and outcomes of regional power behavior in Africa and Asia since 1991, and to identify convergences and divergences in strategies, institutions, and impact on regional stability and integration. Specifically, the study pursues four objectives (1) to map the evolution of regional power capabilities and strategic priorities in select case states in Africa (Nigeria, South Africa, and Kenya) and Asia (China, India, and Japan) from 1991 to 2023; (2) to evaluate the instruments of influence—diplomatic, economic, military, and soft power—employed by these powers within their respective regions; (3) to analyze the effect of regional security architectures and governance mechanisms on power projection and regional order; and (4) to forecast potential trajectories of regional leadership and implications for regional cooperation and conflict risk. The methodology adopts a mixed-methods design combining quantitative and qualitative strands. The population comprises official government documents, defense white papers, foreign policy statements, and multilateral negotiation records from the six focus states, supplemented by regional organization documents (e.g., African Union, ASEAN) and secondary datasets such as SIPRI, World Bank, and IMF indicators. A purposive purposive-stratified sampling approach yields a corpus of 180 primary documents and 60 secondary datasets, with 30 in-depth elite interviews (10 per region) conducted among policymakers, think-tank scholars, and senior military officers, ensuring representation across urban and rural policy theaters. Data collection instruments include a structured document analysis protocol, semi-structured interview guides, and a coding framework aligned with the study’s analytical themes. Validity and reliability are enhanced through triangulation across documents, interviews, and secondary datasets, along with intercoder reliability checks (Cohen’s kappa > 0.75) for the qualitative coding. Data analysis employs a sequential explanatory mixed-methods approach. Quantitative indicators—defense expenditure as a share of GDP, arms trade volume, foreign direct investment flows, and participation indices in regional forums—are analyzed using panel regression (fixed effects) to identify determinants of regional influence and to test hypotheses regarding economic capacity, governance quality, and regional security collaboration. Qualitative data are analyzed thematically using a framework grounded in Neoclassical Realism and Constructivist International Relations theory; the analysis interrogates how material capabilities intersect with perceived regional identities, legitimacy, and normative power. A cross-case synthesis contrasts African and Asian trajectories, with an analytic model that maps capability, intention, opportunity, and outcome (CIOO) to explain differentiation in regional leadership. Expected findings anticipate that economic scale and governance quality strongly predict influence within each region, but with divergence Asian powers leverage dense security architectures and institutionalization to shape regional norms, whereas African powers leverage bilateral diplomacy and resource diplomacy to gain strategic access, with variable success depending on governance legitimacy and domestic stability. The study contributes to knowledge by developing a comparative framework that integrates capability, institutional creativity, and regional legitimation to explain post-Cold War power diffusion. It will refine existing theories of regional power by highlighting how non-Western powers mobilize soft power alongside hard power in distinct regional contexts. Practical implications include policy guidance for regional security architects on managing power transitions and for development planners seeking to harness regional leadership for stability and growth. The conclusion emphasizes the necessity of adaptive regionalism that accommodates diverse governance models while fostering inclusive security arrangements, with recommendations for building more resilient regional forums, transparency in arms and finance flows, and targeted capacity-building programs to mitigate power-constrained volatility.
