Deep-Sea Mining and the Clarion-Clipperton Zone — 2026-09-08
Diplomatic tensions over deep-sea mining escalated this week as China reaffirmed its support for Cook Islands seabed exploration while the US prepares to station a scientist in Rarotonga, highlighting a strategic rivalry in the Pacific. Meanwhile, local environmental groups in the Cook Islands are demanding greater transparency regarding expanding US-linked exploration activities, amid growing political pressure ahead of national elections.

Top developments
China and US vie for influence in Cook Islands seabed sector
On September 8, 2026, China explicitly reaffirmed its support for the Cook Islands’ seabed mineral exploration through continued custom training programs and ocean research surveys. This move coincides with US preparations to station a scientist in Rarotonga, signaling an intensifying geopolitical competition for access to critical minerals in the Clarion-Clipperton Zone and surrounding areas. The dual presence of major powers underscores the strategic value of Pacific Island nations as gatekeepers to seabed resources, complicating the International Seabed Authority’s (ISA) efforts to maintain a unified regulatory framework.

Environmental groups demand transparency on US-linked exploration
Te Ipukarea Society (TIS), a leading environmental NGO in the Cook Islands, issued a call on September 2, 2026, for increased transparency and public oversight regarding the growing involvement of United States investors and government entities in deep-sea minerals exploration. The group argues that current disclosure mechanisms are insufficient given the scale of US-linked activities, which have expanded rapidly as Washington bypasses traditional ISA sponsorship models. This pressure comes as the Cook Islands government navigates domestic opposition to seabed mining ahead of upcoming elections, where the issue has become a central campaign topic.
Regional media highlights "Deeply Dangerous" US fast-track order
The Pacific Islands Report (September 3, 2026) highlighted regional criticism of recent US executive actions aimed at fast-tracking deep-sea mining permits. The report notes that Pacific leaders view the unilateral US approach as undermining the multilateral framework of the ISA, potentially destabilizing the legal regime for seabed exploitation. The bulletin also covered broader regional economic concerns, noting slower growth in the Pacific amid tourism declines, which may increase pressure on governments to seek new revenue streams from seabed resources despite environmental risks.
Local view
Local stakeholders in the Cook Islands are increasingly vocal about the lack of public consent processes for foreign-led exploration. Thomas Tarurongo Wynne, writing in the Cook Islands News (September 5, 2026), emphasized that the voice of Tongareva (the traditional land and sea stewardship system) must precede any discussion of ports, minerals, or great power partnerships. This sentiment reflects a growing unease among indigenous communities who feel marginalized by high-level diplomatic agreements between the Cook Islands, China, and the US.
Context & numbers
- US Permitting Acceleration: Eight companies are currently vying for permits from NOAA and the Interior Department to explore or mine U.S. and international waters, creating what some analysts describe as a "dot-com boom" atmosphere in the sector.
- Nodule City Project: The Port of Brownsville is advancing plans for "Nodule City," a commercial deep-sea mining hub intended to process polymetallic nodules, signaling infrastructure development ahead of potential commercial extraction.
- ISA Status: The ISA Council continues to negotiate the Mining Code, with no finalized exploitation regulations as of early September 2026, leaving a regulatory vacuum that unilateral national actions are beginning to fill.
On the radar
- ISA Assembly: The International Seabed Authority’s Assembly is scheduled to convene shortly, where member states are expected to debate the legitimacy of unilateral licensing regimes like those initiated by the US.
- NOAA Public Comment Periods: Stakeholders should monitor the Federal Register for closing dates on public comment periods regarding consolidated applications for exploration licenses and commercial recovery permits filed under the Deep Seabed Hard Mineral Resources Act.
