The U.S. has long been trying to establish an Extended Continental Shelf in seven offshore areas: the Arctic off Alaska, the Atlantic (east coast), the Bering Sea, the Pacific (west coast), the Mariana Islands, and two areas in the Gulf of America (Gulf of Mexico).

While past the 200nm EEZ, the U.S. ECS seabed stretches as much as 400 miles offshore, protecting exclusive drilling and mining rights in those waters. It’s a real thing under the United Nations Convention on the Law of the Sea (UNCLOS), and the U.S. has been actively mapping these ECS areas since 2003.

And inside our claimed area was recently found the China-flagged research ship Xue Long 2 (Snow Dragon 2), which, at 14,300 tons, is China’s first domestically-built polar research vessel, and only entered service in 2019.

The advanced Finnish-designed vessel, operated by the state-owned Polar Research Institute of China, can accommodate 90 crew and scientists and has helicopter/UAV facilities as well as extensive survey capabilities.

As noted by the USCG PAO:

The U.S. Coast Guard detected and responded to the China-flagged research ship Xue Long 2 on the U.S. Extended Continental Shelf (ECS) in the U.S. Arctic, approximately 290 NM north of Utqiagvik, Alaska, on Friday.

A Coast Guard C-130J Hercules fixed-wing aircraft from Air Station Kodiak responded to the Xue Long 2, an icebreaker operated by the Polar Research Institute of China, and 130 NM inside the ECS boundary.

The U.S. has exclusive rights to conserve and manage the living and non-living resources of its ECS.

“The U.S. Coast Guard, alongside partners and other agencies, vigilantly monitors and responds to foreign government vessel activity in and near U.S. waters to secure territorial integrity and defend sovereign interests against malign state activity,” said Rear Adm. Bob Little, Commander of the U.S. Coast Guard Arctic District.

The C-130J aircraft was operating under the Coast Guard Arctic District’s Operation Frontier Sentinel, which is designed to meet presence with presence in response to adversary activity in or near Alaskan waters.
