Russia's largest war games in recent history have kicked off in the Far East.
Beijing is sending about 3,200 troops, 900 combat vehicles and 30 aircraft to join the drills at a firing range.
The five-day military exercise known as the Vostok-2018 drills in Russia's eastern and central military districts has mobilized nearly a third of the country's soldiers, making it the largest Russian or Soviet military exercise since 1981, Russian Defense Minister Sergei Shoigu said in a statement last month.
It is emphasized that they will be the largest military exercises in the last 37 years.
Russian Federation showcased its most sophisticated air defence system on Wednesday, using it to repel a mock attack from the sky as part of what it describes as its largest-ever military drills.
Big Russia-China war games are apparently going to be routine going forward, the Russian defence minister revealed Wednesday.

Russian President Vladimir Putin on Tuesday (Sep 11) said that Moscow and Beijing plan to use their own national currencies more often in trade deals as Russia's relations with the West deteriorate. Similar Cold War-era drills only included states that were part of the Soviet sphere.
The drills come at a time of escalating tensions between North Atlantic Treaty Organisation and Russian Federation.
The week-long war games dubbed "Vostok-2018"(East-2018) "have kicked off" in far eastern Russian Federation, the defense ministry said. Chinese President Xi Jinping will be in Russian Federation this week to meet with President Vladimir Putin at an economic forum in Russia's far eastern city of Vladivostok.
Meanwhile Russia's foreign ministry has sought to downplay the significance of the sheer volume of forces deployed for Vostok-2018 as well as Chinese cooperation.
He emphasized that "Russia is a peaceful nation", but noted that the country needs to strengthen its military capability to "be ready to protect its sovereignty, security and national interests, and, if necessary, support our allies".
As the USA threatens to impose more sanctions on China, the Pentagon will surely be keeping a close watch on proceedings between Moscow and Beijing. This week, Russian Federation held military exercises in the Mediterranean.
The strengthening of military ties between Russian Federation and China is particularly alarming given rising tensions between each country and Washington.
Kremlin spokesman Dmitry Peskov said the drills were compulsory to safeguard itself amid the present global condition which is quite belligerent and antagonistic.
