A new analysis from the Center for Maritime Strategy warns that the United States' push into seabed mining could inadvertently provide China with a new playbook for gray zone operations. The report suggests that Washington's approach to extracting minerals from the ocean floor may create legal and strategic ambiguities that Beijing could exploit, potentially undermining U.S. interests in the maritime domain.

Seabed Mining: A New Frontier With Old Risks

The race to mine the seabed for critical minerals like cobalt, nickel, and rare earth elements has intensified as nations seek to secure supply chains for green technologies and defense systems. The United States, eager to reduce its dependence on Chinese-controlled rare earths, has shown growing interest in deep-sea mining. However, the Center for Maritime Strategy cautions that this new economic frontier is also a potential theater for strategic competition.

By engaging in seabed mining without a clear, internationally agreed-upon legal framework, the U.S. may create precedents that China can use to justify its own activities. This could include mining in disputed waters or employing civilian vessels for dual-purpose missions, blurring the line between economic activity and military presence.

Gray Zone Tactics in the Maritime Domain

Gray zone operations are actions that fall below the threshold of conventional warfare but are designed to achieve strategic objectives. They often involve ambiguity, deniability, and the use of civilian assets. China has already employed such tactics in the South China Sea, using fishing fleets and coast guard vessels to assert its claims. The report argues that seabed mining offers a new avenue for these tactics, as the activity can be framed as purely commercial while serving strategic ends.

  • Legal ambiguity: The lack of clear rules for seabed mining in international waters creates room for interpretation and exploitation.
  • Civilian cover: Mining vessels and research ships can act as intelligence-gathering platforms or forward-positioned assets.
  • Economic pressure: Control over critical mineral resources can be used as leverage in diplomatic disputes.

The U.S. Approach: Opportunity or Vulnerability?

The United States has not ratified the United Nations Convention on the Law of the Sea (UNCLOS), which complicates its ability to claim seabed mining rights. Instead, the U.S. may rely on domestic legislation and bilateral agreements, a patchwork approach that could be exploited by adversaries. The report suggests that this fragmented strategy may inadvertently grant China the latitude to operate in ways that challenge U.S. interests.

Moreover, the U.S. has been slow to develop its own deep-sea mining capabilities, while China has already conducted multiple exploratory missions in the Pacific. This technological gap, combined with unclear legal positioning, could give China a head start in setting precedents for seabed mining norms that favor its strategic goals.

Recommendations for a More Robust Policy

The Center for Maritime Strategy offers several recommendations to mitigate these risks. These include clearer domestic legislation, increased investment in seabed mapping and mining technology, and greater engagement with international partners to shape the regulatory environment.

By proactively defining the rules of the game, the U.S. can limit the space for gray zone exploitation. The report emphasizes that seabed mining is not just an economic opportunity but a strategic imperative that requires a coordinated, whole-of-government approach.

Conclusion: A Wake-Up Call for Policymakers

The potential for seabed mining to become a new gray zone playbook for China is a wake-up call for U.S. policymakers. As the nation seeks to secure critical minerals, it must also consider the strategic implications of its actions. A reactive, ad-hoc approach could hand China the initiative, with long-term consequences for maritime security and global supply chains.

The report underscores the need for the U.S. to balance economic ambitions with strategic foresight. Without a coherent policy, seabed mining could become another arena where China outmaneuvers the United States, not through direct confrontation, but through the clever use of ambiguity and opportunity.
