Undersea Cables, Geoeconomics, and Security in the Indo-Pacific: Risks and Resilience

July 28, 2025 Research

The Center for Indo-Pacific Affairs (CIPA) is pleased to share that its project on “Undersea Cables, Geoeconomics, and Security in the Indo-Pacific: Risks and Resilience” has been published as a special issue of Marine Policy, the world’s leading journal of ocean policy studies, and as part of CIPA’s own Indo-Pacific Outlook policy brief series.

Submerged deep beneath the ocean, networks of undersea cables form the critical infrastructure that enables the communication and connectivity upon which societies are built. Over 95 percent of global Internet traffic relies on these cables, and they transmit approximately $10 trillion in financial transactions data throughout the global economy daily. Their destruction could bring down the communications systems of multiple countries, and even minor damage could cause significant disruptions. Consequently, undersea cables exist at the intersection of important issues related to marine policy, including politics, economics, maritime security, international law, and governance. The Indo-Pacific has been the most active region for cable construction in recent years, and these networks have also been drawn into the dynamics of US-China strategic competition. On October 26–27, 2023, the University of Hawai‘i at Mānoa Center for Indo-Pacific Affairs convened a two-day conference in Honolulu, Hawai‘i in partnership with Keio University and Khalifa University with the support of a generous grant from the Japan Foundation.
