The US Navy sailed a guided missile destroyer near contested waters in the Sea of Japan “to challenge Russia‘s excessive maritime claims” in a move widely expected to exacerbate strained relations with the Kremlin.
The USS McCampbell sailed in the vicinity of Peter the Great Bay to “uphold the rights, freedoms and lawful uses of the sea enjoyed by the United States and other Nations,” US navy Lt Rachel McMarr said in a statement.
The destroyer carried out what the navy calls a freedom of navigation operation (FONOP).
It comes as the US prepared to send a warship into the Black Sea in response to Russia’s seizure of three Ukrainian vessels and their sailors.
Peter the Great Bay is the largest gulf in the Sea of Japan and is home to Russia’s Pacific Fleet.
A US Navy official told CNN, who first reported the operation, that it was the first FONOP in that area since 1987, when the Soviet Union laid claim to the areas.
The official said the US does not recognise Russia’s claims, which they said far exceed the 12 miles from the Russian coastline guaranteed by international law.
“US Forces operate in the Indo-Pacific region on a daily basis,” Ms McMarr added.
“These operations demonstrate the United States will fly, sail and operate wherever international law allows. That is true in the Sea of Japan, as in other places around the globe.”
She said the US Navy conducts “routine and regular” FONOPs which she said were “not about any one country, nor are they about current events”.
The operation happened on the same day that Russian president Vladimir Putin suggested Moscow could develop intermediate-range nuclear weapons in response to the US quitting a key Soviet-era arms control treaty.
The US secretary of state, Mike Pompeo, gave Russia 60 days to come back into compliance with the agreement before the US would suspend its obligations.
