U.S. Targets 69 Million‑Acre Pacific Seabed Near Guam in Rare‑Earth Race with China

Why It Matters

The proposed lease of 69 million acres of Pacific seabed marks the first large‑scale U.S. attempt to commercialize deep‑sea mineral extraction, a sector that could supply a significant share of the cobalt, nickel and rare‑earth elements needed for electric vehicles, renewable‑energy technologies and defense systems. By reducing dependence on Chinese sources, the United States hopes to safeguard critical supply chains, but the plan also risks irreversible damage to fragile marine ecosystems and could inflame regional tensions. Local opposition in Guam underscores the broader challenge of balancing strategic imperatives with environmental stewardship and community consent. If successful, the project could catalyze a new frontier of offshore mining, prompting other nations to stake claims and potentially leading to a regulatory race‑to‑the‑bottom. Conversely, strong pushback could force policymakers to develop stricter environmental safeguards and more inclusive consultation processes, setting precedents for future ocean‑resource governance.

Key Takeaways

• BOEM proposes leasing 69 million acres (280,000 km²) of Pacific seabed near Guam and the Northern Mariana Islands.
• Targeted minerals include cobalt, nickel, copper, manganese, zinc and rare‑earth elements.
• U.S. executive orders (April 24, 2025) direct accelerated development to counter China’s mineral dominance.
• Governor Lou Leon Guerrero and Sen. William Parkinson publicly oppose the plan, citing environmental and security concerns.
• Arthur D. Little projects the deep‑sea mining sector could eventually be worth up to US$20 trillion.

Pulse Analysis

The U.S. seabed mining proposal is less a commercial venture than a geopolitical lever. By earmarking a tract the size of Nevada for mineral extraction, Washington is signaling to Beijing that it will not cede strategic resources to a rival. This mirrors past moves in the Arctic and space domains, where resource potential is weaponized for diplomatic leverage. However, the initiative also reveals a critical blind spot: the United States lacks a comprehensive legal framework for deep‑sea mining, relying on the 1982 United Nations Convention on the Law of the Sea (UNCLOS) which it has not ratified. The absence of clear, enforceable environmental standards could invite litigation from NGOs and Pacific Island nations, potentially delaying or derailing the project.

Economically, the projected $20 trillion valuation is speculative. Early pilots in the Clarion‑Clipperton Zone have shown that extraction costs, equipment durability, and ore grade variability can erode profitability. The U.S. will need to subsidize early operations or partner with private firms willing to shoulder high upfront risk. If the government can secure a stable supply of critical minerals, it could lower the cost base for domestic EV battery manufacturers and reduce exposure to Chinese export controls, a tangible strategic gain.

Regionally, the plan may accelerate a mining arms race in the Pacific. Nations such as Tonga and the Marshall Islands have already signed deep‑sea mining agreements with Chinese firms, and a U.S. foothold could prompt them to seek competing contracts, fragmenting the Pacific’s environmental governance. The ultimate outcome will hinge on how effectively Washington balances security objectives with transparent, science‑based environmental assessments and genuine engagement with local communities.
