China and Russia are continuing the active phase of their naval drills in the Sea of Japan and the Peter the Great Gulf. The ’Joint Sea 2015 II’ drills involve 22 vessels, 20 aircraft, 40 armored vehicles and 500 marines from both countries. The war games were to culminate on Tuesday in a joint amphibious and airborne landing at the Klerk firing range in Russia’s Far East.

The navies from both countries conducted intensified drills on Monday that included anti-submarine and anti-ship missions as they practiced to jointly cope with maritime security threats. The nine-day exercise that started on the 20th is the second naval drill involving China and Russia this year.
