Seabed mining is a process that extracts and recovers submerged sediment and minerals from the ocean floor, and deep-sea mining involves mining activities at a depth of more than 200 meters. The seabed contains critical minerals like cobalt, copper, nickel, and other rare earth elements.
The letters sounded the alarm about the CCP’s dominance of 95 percent of the global supply chains in critical mineral resources, as well as its processing capability that could “turn these materials into finished products that are crucial to U.S. weapons systems.”
“We cannot afford to allow China to capture and exploit seabed resources, which the CCP has characterized as ‘a new frontier for international competition,’” the lawmakers warned. “We must explore every avenue to strengthen our rare earth and critical minerals supply chains.”
The letters noted that the CCP’s control of this sector is built on environmental violations and human rights abuses, “including attacks against grassroots leaders, water pollution, ecosystem destruction, and unsafe working conditions.”
China accounted for 80 percent of the gallium production in the world and 60 percent of germanium, according to the Critical Raw Materials Alliance.
The lawmakers cited national security strategies to address critical mineral supply chain risks to alert the Pentagon of the importance “of evaluating and planning for seabed mining as a new vector of competition with China for resource superiority and security” to improve the U.S. defense supply chain’s resilience.
The lawmakers then requested information from the Department of Defense regarding using and assessing deep-sea polymetallic nodules in the National Defense Stockpile Program.
“We cannot afford to cede another critical mineral resource to China,” the lawmakers warned. “The United States, and specifically, the Department of Defense, should be engaging with allies, partners, and industry to ensure that China does not seize unfettered control of deep-sea assets.”
Deep-sea Mining
The deep seabed harbors small polymetallic nodules abundant in manganese, cobalt, copper, nickel, and rare earth elements. These deposits are found in international waters, typically located hundreds to thousands of miles away from shore and occurring at depths of 200 meters or more.Deep-sea mining is regulated by the International Seabed Authority (ISA), which was founded in 1994 under the 1982 United Nations Convention on the Law of the Sea (UNCLOS). The ISA can issue licenses for exploration and exploitation of seabed mineral resources to party nations to UNCLOS.
“China is putting pressure on ISA to accelerate its decision-making process to adopt regulations by 2025 or sooner–a demand that comes on the heels of ISA missing a deadline to establish a regulatory framework earlier this year–at which point mining can begin,” the lawmakers wrote.
The United States has not ratified UNCLOS, and therefore it cannot sponsor U.S. companies seeking ISA licenses to explore or exploit seabed mineral resources beyond the United States’ exclusive economic zone.
