Highlights
- China Minmetals obtains first environmental impact statement approval from ISA for deep-sea polymetallic nodule mining vehicle tests.
- The approval positions China at the forefront of deep-sea mining expansion, targeting critical minerals like nickel, cobalt, and manganese.
- This strategic move reflects China’s ambition to become a ‘strong maritime nation’ and potentially reshape global resource access in international waters.
China Minmetals has become the first Chinese entity—and only the fifth globally—to obtain formal approval from the International Seabed Authority (ISA) for an environmental impact statement (EIS) permitting individual tests of deep-sea polymetallic nodule mining vehicles. The EIS, cleared on May 16 and developed by Minmetals’ Changsha Research Institute, authorizes vehicle trials in Block A-5 of China’s contract area in international waters. This milestone positions Beijing at the forefront of deep-sea mining expansion, signaling a significant shift in global access to untapped strategic resources, including nickel, cobalt, manganese, and rare earth elements embedded in seabed nodules.
While framed (opens in a new tab) as a science-based, lawful progression in accordance with international norms, the approval marks a profound geopolitical advance for China’s maritime industrial strategy. Backed by Xi Jinping’s directive to build China into a “strong maritime nation,” the achievement highlights how China is utilizing state-owned enterprises to transform international waters into a new frontier of resource control. Through tightly coordinated bureaucratic, legal, and technical efforts across Minmetals and its subsidiaries, Beijing has now gained legal cover to begin exploiting a frontier where the West remains absent, mainly due to fragmented policy, environmental pushback, and lack of industrial readiness.
For Western nations and strategic allies, how much of the deep-sea mining discussion is hyperbole vs. reality?
China appears to be locking in the next generation of critical mineral supply chains—this time beneath the ocean floor. Of course, actual productivity would be years out, but the Chinese state-backed conglomerates are making noise about this topic.
Unless the U.S., EU, and their partners rapidly develop coordinated frameworks for responsible deep-sea exploration, including research and development, environmental science, and international legal positioning, China will continue to shape the rules and seize the early mover advantage in a domain once seen as too risky, too complex, or too distant. The seabed may be deep, but the strategic consequences are rising to the surface fast.
