Russia and US warships almost collide in East China Sea
Russia's Pacific Fleet said the cruiser USS Chancellorsville crossed just 50m (160ft) in front of the destroyer Admiral Vinogradov at 06:35 Moscow time (03:35 GMT).
It was forced to perform "emergency manoeuvring" to avoid the US ship.
But US forces blamed the Russians, claiming their ship was responsible.
US Seventh Fleet Commander Clayton Doss called the Russians "unsafe and unprofessional", saying their destroyer "made an unsafe manoeuvre against USS Chancellorsville". He dismissed the Russian allegation as "propaganda".
dmiral Vinogradov came within 50 to 100 feet (15m-30m) of the USS Chancellorsville in the Philippine Sea, the US said.
The Russian Pacific Fleet meanwhile said the incident took place in the southeast of the East China Sea, and added they had sent a message of protest to the US ship's commanders.
In a statement it said the US warship had "suddenly changed direction and crossed the path of Admiral Vinogradov just 50m away," forcing the Russian crew to make a quick manoeuvre.
