BEIJING, Sept. 5 -- The border defense troops dispatched by China, Russia and Mongolia conducted the Border Defense Cooperation 2026 joint exercise in a designated tri-border area located in Manzhouli, Inner Mongolia, China, from September 2 to 3, 2026. The joint exercise focused on "jointly preventing and combating reconnaissance and sabotage activities in border areas".

The exercise was set against the scenario where terrorists escaped from Russian border area to the Chinese and Mongolian sides.

During the exercise, the Russian troops dispatched helicopter to conduct air strike; the Mongolian troops blocked the escaping routes and the Chinese drone-assisted combat team detected and locked on the terrorists. Then, under the cover of FPV drones, an assault team advanced rapidly toward the terrorists’ hideout in armored all-terrain vehicles and stormed inside to arrest the terrorists.
