French Polynesia Challenges United States Startup Over Deep-Sea Mining Proposals in Protected Pacific Waters

The government of French Polynesia has formally announced its intention to challenge a proposal by an American startup to conduct exploratory seabed mining in international waters located immediately adjacent to the territory’s maritime borders. Moetai Brotherson, the President of French Polynesia, has expressed grave concerns regarding the lack of diplomatic consultation and the potential for catastrophic environmental degradation in ecosystems that the island nation has spent years working to protect. The dispute highlights a growing geopolitical and environmental rift between Pacific Island nations and the United States over the future of the "global commons" and the extraction of minerals deemed critical for the green energy transition and military infrastructure.

President Brotherson’s administration maintains that while the American company, American Deep Sea Minerals, made a cursory attempt at contact, no meaningful dialogue or formal consultation occurred. Speaking on the matter, Brotherson emphasized that French Polynesia would not remain passive while industrial activities are proposed on its doorstep. The territory’s leadership argues that the proposal violates international norms regarding the rights of Indigenous peoples and the sovereignty of neighboring states over their shared maritime environments.

The Push for Critical Minerals in the Eastern High Seas Pocket 3

At the center of this burgeoning conflict is a specific area of the Pacific Ocean known as the Eastern High Seas Pocket 3. This region is a unique patch of international waters entirely surrounded by the Exclusive Economic Zones (EEZs) of the Cook Islands, Kiribati, and French Polynesia. Because it is technically outside the national jurisdiction of these countries, it falls under the category of the "high seas," yet its proximity to these nations makes any industrial activity there a matter of intense local concern.

American Deep Sea Minerals, a startup backed by Bay Area investors, has submitted an application to the United States government for a permit to explore this region for polymetallic nodules. These potato-sized rocks, found on the abyssal plains of the ocean floor, are rich in manganese, cobalt, copper, and nickel—minerals essential for the production of high-capacity batteries used in electric vehicles and various advanced military technologies.

The application is one of at least a dozen currently under consideration by the National Oceanic and Atmospheric Administration (NOAA). This surge in domestic applications follows a strategic push by the Trump administration to position the United States as a global leader in critical mineral mining. By inviting companies to apply for licenses directly through U.S. domestic regulatory frameworks rather than through international bodies, the administration has signaled a desire to bypass the slow-moving international consensus-building process.

A Clash of Regulatory Frameworks: The ISA vs. Unilateral Action

The move by the United States to authorize mining exploration in international waters has sparked a diplomatic firestorm. Currently, the International Seabed Authority (ISA), a United Nations-mandated body based in Kingston, Jamaica, is the primary organization tasked with regulating mining in the "Area"—the seabed beyond national jurisdiction. For over a decade, negotiators from dozens of countries have been meeting to finalize the "Mining Code," a comprehensive set of environmental and economic regulations intended to govern deep-sea extraction.

Last year, the Trump administration broke from this international trajectory, encouraging American firms to seek permits under the Deep Seabed Hard Mineral Resources Act, a piece of U.S. legislation from 1980. This unilateral approach has been characterized by many international observers as a violation of the United Nations Convention on the Law of the Sea (UNCLOS), which the U.S. has not ratified but generally recognizes as customary international law.

Letitia Carvalho, the Secretary-General of the ISA, recently addressed the assembly in Jamaica, reinforcing the principle that the deep seabed is the "common heritage of mankind." She warned that allowing individual countries or corporations to bypass collective regulation risks repeating the historical patterns of land-based industrial destruction and social injustice on the ocean floor.

French Polynesia finds itself in a complex position within this legal landscape. Because it remains an overseas territory of France, it does not hold an independent seat at the ISA. Furthermore, the Indigenous Ma’ohi people of the territory have long argued that their lack of political self-determination has left them marginalized in global discussions that directly affect their ancestral waters. President Brotherson has noted that while he prefers the international regulatory process of the ISA to the unilateral actions of the U.S., the voices of Pacific Islanders must be prioritized regardless of the forum.

Indigenous Rights and the Principle of Informed Consent

A primary pillar of French Polynesia’s challenge is the failure of the American company and the U.S. government to adhere to the principle of Free, Prior, and Informed Consent (FPIC). Under international law, particularly the United Nations Declaration on the Rights of Indigenous Peoples, Indigenous communities have the right to give or withhold consent for projects that affect their lands, territories, and resources.

President Brotherson revealed that American Deep Sea Minerals sent a brief introductory email to a government representative, to which the French Polynesian government requested further technical details. According to the President, no response was ever received. This lack of communication, he argues, makes it impossible for the territory to assess the environmental risks or the potential impact on their local economy, which is heavily reliant on healthy marine ecosystems.

In contrast, Graham Goulet, the CEO of American Metals (the parent entity of American Deep Sea Minerals), stated that the company intends to consult with the governments of the Cook Islands, Kiribati, and French Polynesia as the exploration program matures. Goulet maintained that these discussions would take place under U.S. oversight and emphasized that the company plans to create benefit-sharing agreements with Pacific nations. However, the timing of this proposed consultation—occurring after the application has been filed—is a major point of contention for Pacific leaders who believe consent must be secured before applications are submitted.

Environmental and Cultural Stakes in the Pacific

The environmental concerns regarding deep-sea mining are profound. Scientists warn that the process of extracting nodules involves massive machinery that would scrape the seafloor, destroying habitat and creating "sediment plumes"—clouds of silt and debris that can travel for hundreds of miles. These plumes can clog the feeding apparatus of marine organisms and disrupt the mid-water ecosystems that support tuna and other commercially vital fish species.

French Polynesia has been a vocal opponent of the industry for several years. In 2022, the territory implemented a ban on seabed mining within its own waters, a move followed by mainland France in 2023. This domestic policy is rooted in both ecological necessity and cultural identity. For the Indigenous population, which makes up 80 percent of the territory, the ocean is not merely a resource but a "sacred place of creation."

Hinano Murphy, an Indigenous cultural expert from Moorea, has frequently spoken about the spiritual connection between the Ma’ohi people and the deep sea. She argues that at a time when climate change is already threatening the existence of island nations, the introduction of "strip-mining" on the ocean floor represents an existential threat to their heritage and future.

President Brotherson’s administration has further codified these protections through the Tainui Atea marine protected area. This preserve, one of the largest in the world, covers nearly the entirety of French Polynesia’s exclusive waters and protects hundreds of species of coral, sharks, and fish. The government argues that allowing industrial mining just outside the borders of this sanctuary would negate the conservation efforts undertaken within it.

Chronology of the Deep-Sea Mining Dispute

• 1980: The U.S. passes the Deep Seabed Hard Mineral Resources Act, creating a domestic framework for mining in international waters.
• 1994: The International Seabed Authority (ISA) is established to regulate the "Area" under UNCLOS.
• 2021: The Republic of Nauru triggers a "two-year rule" at the ISA, forcing the body to finalize mining regulations.
• 2022: French Polynesia officially bans seabed mining within its maritime borders.
• 2023: France announces a total ban on deep-sea mining in its waters and supports a global moratorium.
• Late 2023: The Trump administration invites U.S. companies to apply for exploration licenses through NOAA, bypassing the ISA.
• January 2024: The UN High Seas Treaty takes effect, providing a legal mechanism for nations to establish marine protected areas in international waters.
• June 2024: American Deep Sea Minerals’ application for the Eastern High Seas Pocket 3 is made public, triggering the current diplomatic friction.
• July 2024: ISA delegates meet in Jamaica to continue debating the Mining Code as global opposition to the U.S. unilateral approach grows.

The UN High Seas Treaty: A New Legal Frontier

The timing of this dispute is particularly significant given the recent implementation of the United Nations High Seas Treaty. This landmark agreement allows for the creation of conservation zones in international waters for the first time in history. French Polynesia has expressed interest in using this treaty to designate the Eastern High Seas Pocket 3 as a protected area, which would legally preclude mining activities.

Brotherson believes that the outcome of this case will set a critical precedent for the effectiveness of the High Seas Treaty. If a single nation like the United States can unilaterally authorize industrial activity in a sensitive "pocket" of the high seas, it could undermine the global community’s ability to protect marine biodiversity.

As the public comment period for American Deep Sea Minerals’ application remains open until August 3, the government of French Polynesia is preparing a formal submission to NOAA. They are demanding a comprehensive, independent, and participatory environmental impact assessment that takes into account the interests of all neighboring Pacific nations. While the company claims its current goal is "neutral scientific research," President Brotherson remains skeptical, noting that the research is explicitly designed to pave the way for commercial extraction.

The standoff in the Pacific is more than a local environmental dispute; it is a fundamental test of whether the world’s oceans will be managed through international cooperation and Indigenous stewardship, or through a new era of industrial competition and unilateral resource grabs. For the people of French Polynesia, the answer to that question will determine the health of their "sacred place of creation" for generations to come.
