On 14 March 2025, the G7 Foreign Ministers (Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States of America, and the High Representative of the European Union) issued a Declaration on Maritime Security and Prosperity. The Declaration covers a host of topics and practices of interest to the law of the sea, but select paragraphs include:
3. We recognize the role of the UN Convention on the Law of the Sea (UNCLOS) as the legal framework for governing all activities in the oceans and the seas.
[…]5. Attempts to Change the Status Quo by Force: We oppose unilateral attempts to change the status quo, in particular by force or coercion including in the East and South China Seas. We undertake to implement means through which to track systematically and report on attempts to change the status quo by force and by the establishment of new geographical facts, including through coercive and dangerous actions on the oceans and seas that might threaten regional and international peace and security. […]
6. Protecting Critical Maritime and Undersea Infrastructure: We are seized of the fact that vital energy and telecommunications infrastructure under the oceans and seas connects our economies and is vital to our prosperity. We recall the G7 Joint Statement on Cable Connectivity for Secure and Resilient Digital Communications Networks (2024) and the New York Joint Statement on the Security and Resilience of Undersea Cables in a Globally Digitalized World (2024). We share a growing concern that undersea communications cables, subsea interconnectors and other critical undersea infrastructure have been subject to critical damage through sabotage, poor seamanship or irresponsible behaviour which have resulted in potential internet or energy disruption in affected regions, delays in global data transmission, or compromised sensitive communications. We will enhance our cooperation with industry mitigate risks, reduce bottlenecks to operational tasks while strengthening repair capacities in order to improve the overall resilience of critical undersea and maritime infrastructure. In this respect, we welcome the EU Action Plan on Cable Security adopted in February 2025 by the European Commission and the High Representative of the Union for Foreign Affairs and Security Policy.
[…]10. Curtailing Unsafe and Illicit Shipping Practices: The rise of unsafe and illicit shipping practices, including fraudulent registration and registries, poses a significant threat to global trade and environmental sustainability. We are concerned that unsafe and illicit shipping imposes heavy costs on industry, governments and citizens […] We commit to strengthen our coordination, amongst the G7 and with other partners, to prevent the use of unregistered or fraudulently registered, uninsured and substandard vessels engaged in sanctions evasion, arms transfers, illegal fishing and illicit trade. We encourage relevant International Organizations to improve maritime domain awareness by expanding satellite-based vessel tracking and establishing comprehensive data records of the movement of individual ships and of ship-to-ship transfers, as a means of identifying and tracking illicit maritime activities. […]
11. Shadow Fleet Task Force: We invite members of the Nordic-Baltic 8 (Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway, Sweden), and possibly others, to join participating G7 members in a Shadow Fleet Task Force to enhance monitoring and detection and to otherwise constrain the use of shadow fleets engaged in illegal, unsafe or environmentally perilous activities, building on the work of others active in this area. The Task Force will constitute a response by the participating States to the call by the International Maritime Organization in its Resolution A.1192(33) of 6 December 2023 for Members States and all relevant stakeholders to promote actions to prevent illegal operations in the maritime sector by shadow fleets and their flag states, including illegal operations for the purposes of circumventing sanctions, evading compliance with safety or environmental regulations, avoiding insurance costs, or engaging in other illegal activities.
[…]13. Promoting Safe and Resilient Ports and Strategic Waterways: […] We will work with partners and with relevant International Organizations to encourage robust cybersecurity standards for port ICT infrastructure, to increase resilience against malicious cyber incidents on maritime logistical networks, to reduce monopolistic power over key supply chain nodes, to promote secure and transparent port ownership, to limit unsolicited or undue foreign influence over critical infrastructures and strategic waterways, and to otherwise encourage greater focus on such potential vulnerabilities.
14. Unexploded Ordnance (UXO) at sea poses a significant hazard to the marine environment, to the safety of fishermen and other users of the maritime space, and to various marine economic activities. We commit to enhancing diplomatic efforts and to exchanging best practices among national authorities, relevant international and regional organizations, and relevant industry sectors to accelerate the clean-up of UXO from the seas and ocean.
[…]17. This G7 Maritime Security and Prosperity Declaration provides a framework for cooperation with non-G7 Partners, including countries hosting major ports, large merchant fleets, or extensive flag registries as well as relevant regional and International Organizations, such as the International Maritime Organization and ASEAN. We would welcome robust cooperation with Partners to take forward the goals set out in this Declaration, consistent with the principles of sovereignty and territorial integrity, under the efforts of the G7 countries, including a free, open, prosperous and secure Indo-Pacific region, to build a free and open maritime order based on the rule of law, and of commitment to the sustainable development of the world’s maritime spaces.
On 17 March 2025, A Ministry of Foreign Affairs of China Spokesperson offered remarks on the Declaration on Maritime Security and Prosperity, in particular surrounding the paragraphs addressing the Taiwan Strait and the South China Sea.
