Impact of Transit Diplomacy on Indian Ocean Security (2000–2020)

Thesis Abstract

Transit diplomacy has become a critical mechanism shaping security dynamics in the Indian Ocean, where competing maritime powers, regional states, and international institutions converge over strategic chokepoints, naval access, and energy transit routes. The study addresses the gap in empirical understanding of how transit-oriented diplomacy influences maritime security, freedom of navigation, and risk management in a heterogeneous regional system from 2000 to 2020. The aim is to assess whether and how transit diplomacy has mitigated or amplified security challenges, including piracy, periphery conflicts, and great-power competition, within a multi-polar maritime environment. Specific objectives are (i) to map the evolution of transit diplomacy initiatives among key Indian Ocean littoral states and external actors; (ii) to evaluate the relationship between transit diplomacy activities and changes in maritime security indicators; (iii) to identify institutional arrangements, norms, and confidence-building measures associated with transit corridors; (iv) to assess the role of international organizations and regional mechanisms in mediating security outcomes; and (v) to develop a policy framework for enhancing security through transit-oriented diplomacy. The study employs a mixed-methods research design combining quantitative time-series analysis with qualitative case studies. The population comprises official policy documents, naval doctrines, and multilateral declarations from 2000 to 2020, complemented by interviews with 45 naval officers, maritime security policymakers, and regional analysts selected through purposive sampling. Data collection instruments include a structured coding framework for content analysis of policy texts, a standardized interview guide, and a dataset of maritime security incidents compiled from the International Maritime Bureau and regional security briefs. Validity and reliability are ensured through inter-coder reliability checks (Cohen’s kappa above 0.75) for document coding and triangulation between interview narratives and archival sources. Quantitative analysis utilizes time-series regression to test the association between the intensity of transit diplomacy indicators (e.g., number of joint patrols, diplomatic commitments, and transit corridor agreements) and security outcomes (piracy incidence, insurance premiums, and freedom of navigation violations). Qualitative analysis adopts thematic analysis to identify patterns of cooperation, deterrence, and strategic signaling, supplemented by a cross-case synthesis of three focal settings the Gulf of Aden/Western Indian Ocean, the Malacca- and Singapore-straits nexus, and the Bay of Bengal littoral zone. A conceptual framework drawn from liberal institutionalism and securitization theory guides interpretation, with particular reference to the theories of regime theory and soft balancing. Expected findings indicate that transit diplomacy correlates with measurable declines in piracy incidents and insurance costs when coupled with robust legal-administrative frameworks and joint patrols, though effects vary by nexus and power asymmetry. The study anticipates identifying a set of mediating factors—trust-building measures, transparent transit regimes, information-sharing platforms, and credible enforcement mechanisms—that amplify security benefits. It also expects to show that external actors’ strategic signaling, when aligned with regional stabilizers, reduces misperceptions and lowers the likelihood of security escalation. The contribution to knowledge lies in providing an empirically anchored assessment of how transit diplomacy operates as a security governance instrument in a complex maritime system, bridging gaps between international relations theory and practical naval diplomacy. The study offers a policy framework for sustaining security through transit diplomacy, emphasizing institutional design, inclusive governance, and adaptive management of transboundary risks. The main conclusion posits that transit diplomacy, when integrated within credible security architectures and operationalized through continuous multi-stakeholder engagement, improves maritime security outcomes in the Indian Ocean more effectively than unilateral or ad hoc approaches. Recommendations include expanding joint operational planning and information-sharing platforms, developing standardized transit corridor protocols with dispute-resolution mechanisms, strengthening regional capacity-building programs for surveillance and legal enforcement, and fostering inclusive regional dialogue that aligns great-power competition with regional stability objectives. Further research is advised to examine the longitudinal effects of climate and resource pressures on transit diplomacy effectiveness across evolving geostrategic contours.
