Russia has launched its biggest war games since the fall of former Soviet Union close to its border with China.
Nearly 300,000 troops including Chinese army personnel are participating in the joint exercises of the two countries.
China and Russia have staged joint drills before but not on such a large scale, and the Vostok-2018 exercise signals closer military ties between Beijing and Moscow.
Vostok-2018 is taking place at a time of heightened tension between the West and Russia, and NATO has said it will monitor the exercise closely.
