AKIPRESS.COM - Russia has launched its biggest military exercise since the Cold War, involving about 300,000 service personnel, in eastern Siberia, BBCreported.

China is sending 3,200 troops to take part in "Vostok-2018", with many Chinese armoured vehicles and aircraft. Mongolia is also sending some units.

The last Russian exercise of similar scale was in 1981, during the Cold War, but Vostok-2018 involves more troops.

The week-long manoeuvres come at a time of heightened Nato-Russia tensions.

As the exercises began, Russian President Vladimir Putin met his Chinese counterpart Xi Jinping at a forum in the eastern city of Vladivostok and told him "we have a trusting relationship in the sphere of politics, security and defence".

Relations between Russia and Nato - a 29-member defence alliance dominated by the US - have worsened since Russia annexed Crimea from Ukraine in 2014.

Kremlin spokesman Dmitry Peskov said the drills were justified given "aggressive and unfriendly" attitudes towards Russia.
