Armenia is to leave the Collective Security Treaty Organisation (CSTO), a Moscow-led military alliance of post-Soviet states, Prime Minister Nikol Pashinyan announced on Wednesday.

Pashinyan declared Armenia’s withdrawal during a parliamentary session attended by government ministers, Russian news agency Interfax reported.

“We will leave. We will decide when,” Pashinyan said in response to a question from an opposing MP, as to why Armenia has not already withdrawn from the alliance given their dissatisfaction. “What do you think is the next step? Do you think we will go back? No, there is no other way. Don’t worry, we won’t go back,” Pashinyan added.
