US territories hit out at Trump plan to explore deep sea mining in the Pacific

US agency releases plan to lease millions of hectares of seabed off the coast of the Northern Mariana Islands and Guam

A US government plan to lease out millions of hectares of seabed near the Mariana Trench for deep sea exploration has drawn opposition from US territories in the Pacific, as the Trump administration remains locked in a race with China for control of critical ocean minerals.

On Tuesday, the Marine Mineral Administration (MMA), an agency under the US department of the interior, released a proposal to auction deep sea mining leases for 28m hectares (69m acres) of seafloor off the coast of the Northern Mariana Islands and Guam.
