Bishkek: Kyrgyzstan hosted a leaders' summit of the Collective Security Treaty Organization (CSTO) in its capital, Bishkek. The military alliance conducted both narrow and expanded meetings of its Collective Security Council. These meetings saw participation from nearly all member states' heads of state, including Russian President Vladimir Putin, who was on a three-day state visit to Kyrgyzstan.

According to Anadolu Agency, Armenia was notably absent from the summit, having suspended its participation in CSTO activities back in 2024 due to dissatisfaction with the alliance's response to its security concerns. In addition to the main summit, a meeting comprising foreign ministers, defense ministers, and security council secretaries from CSTO member states was held prior to the Collective Security Council meeting.

The event concluded with CSTO members signing 16 documents, including a Collective Security Council declaration and a statement on combating drug trafficking, as stated by the Kremlin. The summit was conducted under Kyrgyzstan's chairmanship of the organization, with Russia set to assume the alliance's chairmanship beginning January 1, 2026.

The CSTO, established in 2002, is a military alliance that includes Russia and former Soviet states such as Armenia, Belarus, Kazakhstan, Kyrgyzstan, and Tajikistan.
