Key point: Russia is planning more of its usual exercises this Fall and they will continue to include cooperation with units from China.
The Russian army loves it’s grandiose main exercises. Not only do they present a great venue for strategic signaling and shows of force, but they also allow Russia to test its mobilization, logistics, command and communication capabilities with a realistic amount of forces.
The largest foreign participant will be China. The PLA will send over 1600 men into Russia. The Chinese force will consist of mechanized infantry and air-force units. During the previous similar exercise, the Vostok 2018, the Chinese mechanized units operated withing the Russian formations, but it’s unknown how well the integration actually works and whether or not these composite units are actually capable of conducting demanding combat operations.
