MOSCOW -- Russia's Defense Ministry announced Friday a Russian warship prevented a U.S. Navy destroyer from what it described as an attempt to intrude into Russia's territorial waters in the Sea of Japan.
Hours later, U.S. Indo-Pacific Command called the Russian statement false and stated the ships' interaction was "safe and professional."
The incident came as Russia and China conducted joint naval drills in the area, and follows other dangerously close encounters involving Russian and Western warships. It appears to reflect Moscow's intention to raise the stakes in deterring the U.S. and its allies from sending their ships on missions near Russian waters, as relations between Russia and the West are at a post Cold War low.
The ministry said that the Russian navy's Admiral Tributs destroyer closely approached the U.S. destroyer USS Chafee to chase it out of the area near Russian waters that was declared off limits to shipping due to the gunnery drills there as part of the Russia-China maneuvers.
It said the Russian vessel came close to the U.S. warship after it had ignored repeated warnings to leave the area in the Peter the Great Gulf. The ministry charged that after making "an attempt to cross the Russian sea border," the U.S. warship changed course when the two ships were 66 yards away from each other and sped away.
In a statement, U.S. Indo-Pacific Command said the Chafee was conducting routine operations in international waters when the Russian destroyer came within about 65 yards of the Chafee as it was preparing for flight operations. It added that although Russia had issued a Notice to Airmen and Mariners to avoid that area for a period later in the day, the notice was not in effect at the time of the ships' interaction.
"At all times, USS Chafee conducted operations in accordance with international law and custom," the U.S. statement read.
The Russian statement denounced the U.S. destroyer's maneuvers as a "crude violation" of the international rules on averting ships' collision and a 1972 agreement between Moscow and Washington on preventing air and naval incidents and summoned the U.S. military attache to protest what it described as its crew's "unprofessional action."
Russia, the U.S. and its NATO allies have frequently accused each other of dangerous and provocative maneuvers at sea and in the air as Russia-West ties have been hit by Moscow's annexation of Crimea, accusations of Russian interference with elections, hacking attacks and other tensions.
In June, Russia said one of its warships fired warning shots and a warplane dropped bombs in the path of British destroyer Defender to drive it away from Black Sea waters near the Crimean city of Sevastopol. Britain denied that account, insisted its ship wasn't fired upon and said it was sailing in Ukrainian waters.
Like most of the world, Britain recognizes Crimea as part of Ukraine despite the peninsula's 2014 annexation by Russia.
June's incident marked the first time since the Cold War that Moscow acknowledged using live ammunition to deter a NATO warship, underlining the rising threat of military collisions amid Russia-West tensions.
In the aftermath of the incident Moscow warned that it is prepared to target intruding warships if they fail to heed warnings. In a statement intended to signal Russian resolve, Russian President Vladimir Putin said the incident couldn't have triggered a global conflict even if Russia had sunk the warship because the West knows it can't win such a war.
In other recent naval incidents, the Russian military said the British destroyer HMS Dragon intruded into Russian waters near Crimea in October 2020, and the U.S. destroyer USS John S. McCain was accused of violating the Russian border in the Peter the Great Gulf in the Sea of Japan in November.
In the aftermath of those incidents, Russia rejected the U.S. and British arguments that their warships were exercising the right of so-called "innocent passage" under international maritime law.
Retired Adm. Viktor Kravchenko, the former Russian navy chief of staff, said Friday's incident could have had grave consequences.
