17 Nations Launch Framework to Protect Underwater Infrastructure

Seventeen nations, including Malaysia, Singapore, and Australia, have launched a new voluntary framework aimed at safeguarding critical underwater infrastructure from potential attacks [1]. Known as the Guiding Principles for Underwater Infrastructure Defence Exchanges (GUIDE), the initiative was introduced on May 30 during the 23rd Shangri-La Dialogue in Singapore to enhance international cooperation on subsea security [1].

Key takeaways

• The GUIDE framework is a voluntary, non-legally binding initiative designed to facilitate information sharing and the development of international security norms [1].
• Participating nations include Singapore, Malaysia, Australia, Britain, Brunei, Estonia, Finland, France, Italy, Latvia, Lithuania, the Netherlands, New Zealand, the Philippines, Qatar, Sweden, and Thailand [1].
• The framework addresses the growing vulnerability of subsea telecommunications cables, which carry over 95 percent of global internet and data traffic, as well as energy pipelines [1].
• Defence establishments involved may contribute maritime assets like ships and aircraft to support surveillance and incident response efforts [1].

Addressing Global Subsea Vulnerabilities

The launch of GUIDE follows a series of high-profile incidents involving damage to subsea cables and pipelines, which have highlighted the complexities of responding to security threats in international waters [1]. These challenges include difficulties in determining jurisdiction, enforcing laws, and attributing responsibility for damage [1]. Recent years have seen cable-cutting incidents in the Baltic Sea and near Taiwan, leading to increased scrutiny of how nations protect these essential networks [1].

While the framework is civilian- and industry-led, it acknowledges that defence establishments play a vital role in supporting national agencies [1]. Participating countries intend to use the platform to share best practices, technical knowledge, and early warning information regarding security incidents [1]. The initiative does not create new legal obligations and is intended to operate in accordance with existing international law, including the 1982 United Nations Convention on the Law of the Sea [1].

Why it matters

The security of subsea infrastructure is increasingly viewed as a matter of global economic and connectivity stability, as any disruption to these networks can have widespread negative consequences [1]. Singapore’s Defence Minister Chan Chun Sing emphasized that an attack on one part of the network effectively acts as an attack on the entire system [1]. Moving forward, the participating nations aim to establish clearer international norms for the maintenance and protection of this infrastructure [1]. While the current 17 members have endorsed the framework, other countries have expressed interest in joining and are currently awaiting domestic approval to participate [1].
