Pacific Research Pact Sets the Seabed Stage

Cook Islands and China advance a research focused MoU that excludes extraction while building early capacity for future critical mineral decisions

25 Nov 2025

The Cook Islands has signed a five-year research pact with China aimed at expanding scientific studies of the Pacific seabed, in a move that highlights growing interest in undersea minerals while global rules for commercial activity remain unfinished. Both governments have stressed that the agreement does not grant any licence to extract resources.

The memorandum, concluded in mid-February, establishes joint surveys, seabed mapping and shared use of scientific equipment. Officials in Rarotonga view the arrangement as a chance to build technical skills and broaden the country’s economic options. For China, the work offers early access to data in a region known for cobalt- and nickel-rich deposits.

The timing comes as the International Seabed Authority continues to debate standards for commercial mining, leaving companies without clear guidance. By advancing a research-only partnership, the two governments are moving ahead while other states wait for the regulatory framework. Analysts say early positioning may help shape future decisions once global rules are settled.

Cook Islands officials have emphasised that the focus is scientific. Planned work includes environmental assessments, geological sampling and detailed data sharing, which authorities say are required before any policy decisions. The agreement can be reviewed or renewed at the end of its five-year term.

Environmental campaigners remain cautious, arguing that deep-sea ecosystems are still poorly understood and vulnerable to disturbance. Some critics also highlight the geopolitical implications of closer collaboration with Beijing, noting that control of undersea resources has become a strategic issue for Pacific states.

Industry observers, however, suggest the pact could serve as a model for incremental preparation based on evidence rather than commercial urgency. As demand for minerals used in clean-energy technologies grows, governments are seeking clearer knowledge of seabed conditions. The Cook Islands-China partnership reflects how states may study and plan while keeping commercial mining out of scope.
