China, Russia, and Mongolia hold joint exercise "Border Cooperation -2025"

According to the "China Military" Weibo account, from September 8th to 9th, China, Russia, and Mongolia organized a joint drill in a certain area of the China-Russia-Mongolia border on the topic of "joint prevention and combat of terrorist activities in border areas." This is the first time the three parties have organized border defense forces to participate in a joint exercise. The purpose of this joint drill is to enhance the level of strategic cooperation among the three parties, strengthen their ability to respond to border security threats, further consolidate strategic mutual trust, demonstrate practical cooperation, and deepen traditional friendship. During the exercise, the three parties established a joint command post in Chinese territory, following the principle of "the lead in whose territory, multilateral negotiation, parallel command." By organizing joint planning, joint reconnaissance, joint control, joint strikes, and joint transfers during the exercise, the new model of border defense cooperation was fully tested. After the formal exercise, the three parties also conducted exchanges on specific subjects related to border control.
