From September 8 to 9, China, Russia and Mongolia held the Border Defense Cooperation 2025 joint exercise in north China's Inner Mongolia Autonomous Region. It marks the first time that the three countries have deployed their border defense troops for a joint exercise. Focused on joint prevention and suppression of terrorist and destructive activities in border areas, the joint exercise aims to enhance the strategic coordination among the three parties and strengthen their ability to counter border security threats.
An opening ceremony was held on the morning of September 8, and then the participating troops began to conduct live-force drills. During the drills, the three parties established a joint command post within the Chinese territory. Through activities such as joint planning, joint reconnaissance, joint containment, joint strike, and joint handover, the drills demonstrated a new model of border defense cooperation.
The drills employed a variety of modern reconnaissance and surveillance methods, including battlefield reconnaissance cameras, battlefield surveillance radars, and unmanned aerial vehicles, to strengthen the three countries' border control and patrol capabilities and enhance their technology-driven border management.
The three sides also comprehensively employed a combination of fixed and mobile assets, day and night operations, aerial and ground forces, as well as human and intelligent means, to form a multidimensional encirclement of terrorists and carry out joint arrest.
After the live-force drills, the border troops of China, Russia, and Mongolia will organize the demonstration of military working dogs operations in the Russian territory and hold cultural performances and exchanges in Mongolia.
This joint exercise serves as a historic testament to the long-standing development of friendly and neighborly relations among the three countries and represents a strong action to jointly safeguard peace and stability in the border regions.
