By Du Juan, Zhang Tianye, Li Qingtong, Liu JInkui, Zhao Xiaolei, Zhang Wei, Chen Xiaodong, Li Zhenghua, Long Xitao, Li Pengru and Deng Siqi 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.

Summary

Machine summary

Border defense troops from China, Russia, and Mongolia conducted the 'Border Defense Cooperation 2026' joint exercise at the tri-border area near Manzhouli, Inner Mongolia, on September 2–3, 2026, rehearsing a scenario in which terrorists flee from Russian territory into Chinese and Mongolian border zones; the exercise integrated Russian helicopter strikes, Mongolian blocking forces, and a Chinese drone-assisted assault team using FPV drones and armored all-terrain vehicles. The trilateral format and counterterrorism framing extend a recurring pattern of border-security exercises among the three states, with the specific combination of FPV drone overwatch and armored all-terrain vehicle assault documenting how Chinese border units are incorporating commercial drone tactics into joint operations. What the article does not establish is which Chinese unit or formation provided the assault team, leaving the exercise's organizational chain on the Chinese side unspecified.
