Russia's Pacific Fleet on Friday accused a U.S. warship of nearly causing a collision with a Russian military vessel in the East China Sea due to what it called dangerous manoeuvring, Russian news agencies reported.

The Russian Navy was cited as saying that the USS Chancellorsville, a guided-missile cruise, had come within just 50 metres of the Russian destroyer Admiral Vinogradov which had been forced to take emergency action to avoid a collision.
