This policy position has introduced complexities in its partnerships, particularly with international firms. Critics highlight that the efforts may infringe upon the Law of the Sea treaty, which restricts mining in international waters unless there is a global consensus on regulatory protocols. Notably, nearly every nation, with the sole exception of the U.S., has committed to this treaty, which emphasizes the preservation of the seabed as a "common heritage of mankind."

In light of the potential contraventions of international law, The Metals Company’s previous collaborators are reconsidering their engagements. A notable Japanese partner has expressed the need for careful deliberations, emphasizing the importance of maintaining international credibility in business decisions. This emerging legal landscape has prompted discussions on sustainable practices in seabed mining, underscoring the tension between rapid advancements in mining technology and the pressing necessity for global dialogue on environmental stewardship.

With the seabed mining industry poised for potential growth, the implications of U.S. policy could resonate across international borders, necessitating vigilance as stakeholders navigate through legal and ethical challenges surrounding the Earth's oceans.
