President Vladimir Putin is expected to attend Vostok-2018 after hosting an economic forum in Russia's far eastern city Vladivostok where his Chinese counterpart Xi Jinping is one of the prominent guests.
The military exercises come at a time of escalating tensions between Moscow and the West over accusations of Russian interference in western affairs and ongoing conflicts in Ukraine and Syria.
The Russian army has compared the show of force to the USSR's 1981 war games that saw between 100,000 and 150,000 Warsaw Pact soldiers take part in "Zapad-81" (West-81) -- the largest military exercises of the Soviet era.
But Defence Minister Sergei Shoigu said this time would be even larger, with 300,000 soldiers, 36,000 military vehicles, 1,000 planes and 80 warships taking part in the drills.
"Imagine 36,000 military vehicles moving at the same time: tanks, armoured personnel carriers, infantry fighting vehicles -- and all of this, of course, in conditions as close to a combat situation as possible," Shoigu said.
