President Vladimir Putin will chair a Collective Security Treaty Organization (CSTO) summit in Moscow on November 11, according to the Russian news agency TASS. The Assembly will meet in the capital to review security cooperation and decide on leadership changes.
The CSTO is a regional alliance of former Soviet states that coordinates defense and security policy. Its members meet regularly to strengthen their collective defence against external threats.
During the summit, the leaders plan to discuss key aspects of cooperation and strengthen the CSTO’s collective security system. The event will also cover urgent international and regional issues and include the signing of several multilateral documents.
Most notably, the council will adopt a decision on transferring the organization’s chairmanship from Russia to Tajikistan effective January 1 2027. This shift marks the first time another member will take the top role.
Armenian media outlet 1in.am reported that CSTO leaders might consider suspending Armenia’s voting rights at the meeting. The report said that the discussion could touch on Armenia’s role within the alliance.
Armenian diplomat Simonyan will also attend a CIS security council secretaries’ meeting in Moscow, as noted by a Facebook post from Armenpress. His presence signals Armenia’s ongoing engagement with the organization.
The summit is critical for the participating countries because it shapes how they respond to regional security challenges, such as conflicts in neighboring areas. The decisions made could influence which nations receive support and how collective defense strategies evolve.
With the chairmanship set to transition to Tajikistan next year, the November meeting serves as a key moment for leadership continuity and for solidifying the CSTO’s role in the region’s security landscape.
