Undersea cable security in the Indo‐Pacific: Enhancing the Quad’s collaborative approach

Abstract

Undersea communication cables carry the bulk of global communications, intelligence, and financial transactions daily. They are increasingly threatened, and Australia, Japan, India, and the US have begun coordinating cable security activities in the Indo-Pacific as the Quad. This article investigates the Quad’s role in undersea cable communication security, and analyzes its motivations, strengths, and the challenges it faces thereby illuminating the Quad’s evolving position in international security and its role in global governance. In doing so, it evaluates the Quad’s significance in addressing emerging security threats in the Indo-Pacific, attempts to fill critical gaps in policy formulation, and contributes to theories of informality and global governance. It begins by outlining threats to undersea communication cables. Second, it details the Quad Partnership for Cable Connectivity and Resilience within the context of an informal intergovernmental organization literature. Third, it provides recommendations for policy formulation in undersea cable security and explores the Quad's potential for improving connectivity, resilience, and security. Finally, the article emphasizes the need to tailor policies to India’s unique position within the Quad and explores proactive measures like floating Quad-supported cable repair ships. These recommendations offer insights for policymakers to bolster global communication infrastructure, resilience, and provide public goods amidst multipolarity and great power rivalry.
