Launch of the Guide at Shangri-La Dialogue
On Saturday, defence ministers and representatives from seventeen nations gathered at the Shangri-La Dialogue in Singapore to launch the Guiding Principles for Underwater Infrastructure Defence Exchanges (Guide). The initiative seeks to create a framework for cooperation on the defence of critical marine assets, particularly submarine telecommunications and energy cables that underpin global connectivity. The ceremony took place at the Shangri-La Dialogue, where defence ministers and representatives from the participating countries gathered.
Participants and Scope
The signatories of the Guide are Singapore, Brunei, Malaysia, the Philippines, Thailand, Australia, New Zealand, Qatar, Estonia, Finland, France, Italy, Latvia, Lithuania, the Netherlands, Sweden and the United Kingdom. Notably, the United States and China were absent from the list of participants.
Official Remarks from Singapore
Singapore’s Defence Minister Chan Chun Sing highlighted the dual role of waterways as trade routes and hosts of essential underwater infrastructure. He emphasized the need for international norms governing the installation, maintenance and protection of such assets. The Guide explicitly calls for joint exercises, information sharing and the development of common response protocols.
Analyst Concerns Over Missing Superpowers
Security analysts cautioned that the effectiveness of the Guide could be limited without the involvement of the United States and China, the two largest users and potential threats to undersea cable networks. Their absence, analysts argue, may undermine collective security efforts and leave gaps in enforcement.
Data: The Seventeen Signatories

These countries span the Indo-Pacific, Europe and the Middle East, reflecting a geographically diverse coalition focused on maritime infrastructure defence.
Significance for Global Connectivity
Underwater cables carry the majority of international data traffic and support energy transmission links. Disruption of these lines could impair telecommunications, financial services and energy markets. By establishing a collaborative platform, the signatories aim to share best practices, coordinate threat assessments and develop joint response mechanisms.
Conflicting Perspectives & Gaps
The source material does not provide statements from the United States or China regarding their non-participation, nor does it detail specific operational plans under the Guide. Consequently, the extent to which the framework can address technical or legal challenges remains unclear.
Verbatim Quote
> “Today, if we are honest with ourselves, we will know that we have quite a lot of work to do to establish the international norms on how we can lay those critical infrastructures … but more importantly, how to maintain them and how to prevent people from disrupting them.” — Chan Chun Sing, Singapore Defence Minister
Outlook and Next Steps
The Guide calls for ongoing collaboration among the seventeen nations to explore potential areas of security cooperation for under-sea infrastructure. It also seeks to develop shared norms for laying, maintaining and protecting these assets.
