In December 2023, the US authorities released official coordinates of the extended continental shelf (ECS) beyond 200 nautical miles from the coast in the Arctic, Atlantic (east coast), Bering Sea, Pacific (west coast), Mariana Islands, and two areas in the Gulf of Mexico.
According to the ministry, Russia said that it does not recognized the changes in the US ECS during an ongoing session of the International Seabed Authority in Jamaica.
"The US's unilateral steps do not comply with the rules and procedures established by international law … A corresponding demarche was sent to the American side via a bilateral line in past," the ministry said.
