Introduction

China’s expanding seabed mapping and ocean-surveillance missions—under the guise of scientific research—signal a calibrated dual-use civil–military strategy, with significant implications for India’s maritime security and the Indo-Pacific balance.

Body

These activities enhance China’s undersea domain awareness (UDA), critical for submarine warfare. Detailed bathymetric data, acoustic profiles, and choke-point mapping (e.g., near Andaman & Nicobar, Malacca Strait) improve PLA Navy (PLAN) stealth, navigation, and anti-submarine warfare. Platforms like research vessels (e.g., Dong Fang Hong series) and autonomous sensors blur the line between civilian science and military reconnaissance. Legally, China leverages ambiguities in UNCLOS provisions on marine scientific research in EEZs, often operating in contested or sensitive waters.

For India, the challenge is both tactical and strategic. Tactically, such mapping can expose vulnerabilities of India’s sea-based nuclear deterrent (SSBNs) and naval deployments. Strategically, it complements China’s “string of pearls” presence—ports and access arrangements from Gwadar to Hambantota—facilitating sustained Indo-Pacific reach. Regionally, it undermines freedom of navigation norms and raises concerns among ASEAN states, contributing to a gradual shift in the maritime balance.

However, the threat must be contextualised. Marine research is not per se unlawful, and India itself engages in hydrographic surveys. The real issue lies in opacity, scale, and strategic intent, rather than mere activity. Over-securitisation could also constrain legitimate scientific cooperation.

Conclusion / Way Forward

India must respond through a multi-layered strategy: strengthen maritime domain awareness (IFC-IOR, satellite and seabed sensors), enhance naval capabilities and ASW, and leverage partnerships (QUAD, IOR littorals) for information sharing. Simultaneously, it should push for clearer UNCLOS norms on dual-use research. Balancing deterrence with rule-based engagement is key to preserving a free, open, and stable Indo-Pacific.
