China, Russia, Mongolia step up security ties with border exercise

China, Russia and Mongolia held their first joint border defence drills this week, the Chinese military said on Tuesday, underscoring closer security coordination among the three neighbours.
The exercise, called “Border Defence Cooperation – 2025”, took place on Monday and Tuesday in an unidentified border region shared by the three countries, the People’s Liberation Army said in a post on its official Weibo account.
The live drills aimed to “enhance strategic cooperation among the three sides, strengthen the ability to deal with border security threats, and further consolidate strategic mutual trust,” the military said.
During the exercises, a joint command post was set up on Chinese territory operating under the principle of “whoever’s territory, that side takes the lead, with multilateral consultation and parallel command,” the Weibo post said.
