Leaders of the Collective Security Treaty Organisation voted at a summit in Moscow on Wednesday to strip Armenia of its voting rights and its ability to nominate citizens to quota-based positions within the bloc, citing Yerevan’s failure to meet its financial obligations to the organisation’s budget over several years.
The decision was taken under Article 25 of the CSTO charter, which allows member states to suspend the rights of any country that has not settled its budget arrears for two consecutive years. The measure was reported by the Russian state news agency TASS.
Kremlin spokesman Dmitry Peskov confirmed the outcome after the meeting. “The topic was raised and a decision was taken,” Peskov said. “Given that Armenia had not been fulfilling its obligations for several years already, and guided by the organisation’s charter, it was proposed and decided to deprive Armenia of its voting rights and of the right to appoint its representatives to senior positions in the CSTO.”
Armenia retains a path back to full membership rights: the charter provision applied on Wednesday specifies that suspended rights are restored upon full repayment of outstanding debts to the organisation’s budget. No figure for the arrears was disclosed in the summit communiqué or in Peskov’s remarks as reported by TASS.
The move formalises a deterioration in relations between Yerevan and the Moscow-led security bloc that has been visible for some time. Armenia has grown increasingly distant from the CSTO since the 2020 Nagorno-Karabakh war and the subsequent fall of the enclave in 2023, episodes during which Yerevan argued the organisation failed to come to its defence. Armenian Prime Minister Nikol Pashinyan has repeatedly questioned the value of CSTO membership and has curtailed his country’s participation in joint exercises and meetings, though Yerevan has stopped short of formally withdrawing.
The financial mechanism invoked on Wednesday provides the organisation with a procedural, rather than explicitly political, basis for the suspension — framing what is widely seen as a geopolitical rupture in the language of unpaid dues. Whether Armenia moves to clear the arrears and reclaim its rights, or treats the suspension as a further step toward eventual departure, will determine the practical significance of Wednesday’s vote.
