Russian chairwoman: Armenia will lose a lot if it leaves CSTO

Armenia will lose a lot if it decides to withdraw from the Collective Security Treaty Organization (CSTO), Chairwoman of Russia's Federation Council Valentina Matviyenko said while speaking to journalists following her visit to Vietnam, APA reports.

According to her, Armenia must decide for itself whether to continue its membership in the CSTO.

"What happens next is Armenia's own right — to maintain its membership in the CSTO or to leave the organization. I think that if Armenia makes the opposite decision, it will lose a lot," Matviyenko emphasized.

The Chairwoman of Russia's Federation Council also stated that Armenia's efforts to join the European Union (EU) are incompatible with its participation in the Eurasian Economic Union (EAEU).

Note that Armenia announced the suspension of its participation in the CSTO in February 2024. Yesterday, at the CSTO summit held in Moscow, Armenia was deprived of its voting rights in the organization.
