Key Points

  • This bipartisan Senate resolution calls on the Senate to ratify the United Nations Convention on the Law of the Sea (UNCLOS), a global treaty that governs how countries use the world's oceans for navigation, fishing, and mineral extraction. The U.S. helped draft the treaty but has never officially joined it.

  • Supporters argue that joining UNCLOS would give the U.S. a seat at the table to vote on ocean policy and directly challenge countries like China and Russia when they violate maritime rules. Right now, the U.S. follows these rules but has no formal standing to participate in disputes or negotiations.

    From policy text

    becoming a party to the treaty would give the United States standing to participate in discussions relating to the treaty and thereby improve the ability of the United States to intervene as a full party to disputes relating to navigational rights

  • The resolution highlights the strategic importance of the treaty for the Arctic, where melting ice is opening new shipping routes and access to resources. Without ratifying UNCLOS, the U.S. cannot formally claim its extended continental shelf off Alaska, which could stretch more than 600 nautical miles.

    From policy text

    becoming a Party to the Law of the Sea Convention would allow the United States to fully secure its rights to the continental shelf off the coast of Alaska, which is likely to extend out to more than 600 nautical miles

  • Joining the treaty would let the U.S. participate in the International Seabed Authority, which controls deep-sea mineral extraction as global demand for critical minerals grows. The resolution also notes that over 97% of global internet traffic runs through undersea cables on the ocean floor.

    From policy text

    becoming a party to the treaty would allow the United States to be a member of the International Seabed Authority and thereby participate directly in setting and voting on the policies organizing and controlling mineral-related activities in the international seabed area as global demand for critical minerals increases

  • The resolution is non-binding. It does not itself ratify the treaty but expresses the sense of the Senate that ratification should be a top priority, particularly given challenges in the Indo-Pacific, Arctic, and Black Sea regions.

    From policy text

    recommends the ratification of the UNCLOS remain a top priority for the Federal Government, the importance of which was most recently underscored by the strategic challenges the United States faces in the Indo-Pacific, the Arctic, and the Black Sea regions
