Participants at the Collective Security Treaty Organization summit held in Moscow on November 11 under the chairmanship of Vladimir Putin decided to suspend Armenia's voting rights in the organization, as well as its right to appoint representatives to senior positions in the CSTO. Russian presidential press secretary Dmitry Peskov announced the decision.
Armenia announced in 2024 that it was “freezing” its participation in the CSTO, although this is not provided for in the organization's charter, and stopped paying membership dues.

“The decision was predetermined. We were forced to make it. We tried by every means to draw the Armenian leadership's attention to its own national interests. In the end, we adopted a formula under which Armenia is not expelled from the CSTO; its voting rights are simply suspended,” Konstantin Zatulin, a member of the State Duma Committee on CIS Affairs, told RIA Novosti.
President of Belarus Alexander Lukashenko, President of Kazakhstan Kassym-Jomart Tokayev, President of Tajikistan Emomali Rahmon and President of Kyrgyzstan Sadyr Japarov attended the summit. The leaders signed the CSTO's counterterrorism strategy through 2030. Belarus's Foreign Ministry called for limiting “pseudo-allies'” access to the organization's documents, TASS reported.
That same day, Armenian President Vahagn Khachaturyan signed a law ratifying a framework agreement with the United States on the “Trump Route for International Peace and Prosperity” project, which is intended to connect Azerbaijan with the Nakhchivan Autonomous Republic through Armenian territory.
