In brief

• The Collective Security Treaty Organization suspended Armenia's voting rights over unpaid membership dues.
• Armenia's membership is not ended, and it can be reinstated once it settles its arrears.
• The dispute traces back to Azerbaijan's 2023 offensive in Nagorno-Karabakh, which Yerevan says the alliance failed to counter.

What the CSTO decided

The Collective Security Treaty Organization stripped Armenia of its voting rights on Wednesday, citing unpaid membership dues (CSTO Strips Armenia of Voting Rights – The Moscow Times). The alliance, which Russia leads and whose five members are all former Soviet republics, said the step does not end Armenia's membership.

Secretary-General Taalatbek Masadykov said Armenia could be reinstated, including by sending staff and taking part in the organization's work, once it settles what it owes.

Kremlin position

The Kremlin said Armenia had not met its obligations under the alliance's charter for several years. Its spokesman told a state media reporter that Yerevan would be answered, without giving details of a reply.

Background: Nagorno-Karabakh

The rift dates back to 2023, when Azerbaijan moved to seize the breakaway region of Nagorno-Karabakh in a sudden military operation. Yerevan accused the CSTO of failing to intervene and has since accused the alliance of not acting on its commitments.

Yerevan's stance

Prime Minister Nikol Pashinyan has effectively frozen Armenia's involvement in the CSTO. Last week he said Armenia no longer has any interests tied to the organization.

What comes next

The Kremlin has promised a response, but no timeline has been announced. Whether Armenia pays its arrears and returns to full participation will determine whether the suspension of its voting rights remains in place.
