A new policy paper has highlighted how India, the United States, Japan and Australia — both individually and collectively through the Quadrilateral Security Dialogue (Quad) — are emerging as key players in strengthening port infrastructure and maritime connectivity across the Bay of Bengal (BoB), one of the world’s most crucial trading hubs.
Ports serve as gateways to global commerce, handling over 80% of global merchandise trade. The BoB region alone processes nearly 30% of global trade flows, with Colombo (Sri Lanka), Chennai (India) and Chattogram (Bangladesh) among its most critical ports. Yet despite its strategic value, the region continues to suffer from infrastructural gaps, fragmented governance, inefficiencies, and rising geopolitical tensions.
According to the paper, India has significantly scaled up investments in port modernisation, logistics integration, and greenfield port development — driven by both economic imperatives and strategic considerations. With the BoB becoming a focal point of global supply chains and major-power rivalries, India has turned to the Quad to pool resources, enhance maritime resilience and counterbalance China’s growing footprint.
The Quad’s recognition of ports as strategic assets — first articulated at the 2021 Leaders’ Summit — has accelerated cooperation in areas such as green shipping, smart-port technologies, cybersecurity, and resilient supply chains. Each member brings distinct strengths: Japan’s financing capacity, the US’s technological expertise, Australia’s risk-management and capacity-building skills, and India’s trade facilitation experience and geographic advantage.
The paper proposes a three-part framework outlining how India can navigate cooperation with Quad partners:
1. Strengthened Bilateral Engagements:
India continues to be a preferred development partner for its neighbours, enabling customised, security-sensitive infrastructure solutions. However, this limits the broader financial and technological benefits that Quad cooperation could unlock.
2. Diplomatic Quad Involvement in Select Infrastructure:
A hybrid model where India leads projects but draws on targeted Quad expertise — such as Japan’s green-shipping know-how or Australia’s PPP training. While offering flexibility, managing multiple partners could complicate decision-making and strain ties with countries economically linked to China.
3. Full Quad Alignment on Port Development:
A comprehensive collaborative model that combines the financial, technological and institutional capabilities of all four members. This would significantly accelerate BoB connectivity but may require India to dilute some strategic autonomy and could reinforce perceptions of the Quad as an anti-China bloc.
The study concludes that India’s engagement with the Quad in the Bay of Bengal remains both complex and essential. By strategically choosing the right model of cooperation, India can bolster regional connectivity, strengthen its maritime influence, and ensure sustainable development across the Indo-Pacific’s most dynamic waters.
