Summary

Machine summary

China, Russia, and Mongolia will hold the trilateral 'Border Defense Cooperation-2026' joint exercise in early September, the second iteration of this series, focused on joint planning, search, strike-and-apprehension, and handover operations against reconnaissance and sabotage in border areas. The exercise documents an institutionalizing trilateral border security mechanism — moving from a one-off event toward a recurring format — at a moment when China-Russia military cooperation is under sustained Western scrutiny. What remains unknown is which specific border defense units from each country will participate and at what scale.
