ArmInfo. Russian Foreign  Minister Sergey Lavrov has stated that Armenia's desire to withdraw  from the Collective Security Treaty Organization (CSTO) is a  sovereign one and the organization is not  closing its doors to  Yerevan.  "No document on Armenia's withdrawal from the CSTO has been  received. We hear all these talks. The Prime Minister of Armenia has  addressed and extensively discussed this topic in parliament. We are  not imposing anything on anyone. But we are convinced that it is in  Armenia's security interests  to use CSTO membership to the fullest  extent. If a decision is made, which he speaks of as a foregone  conclusion, it will be the sovereign right of the current Armenian  leadership," he said after the OSCE Ministerial Council meeting, as  quoted by RIA Novosti.  "Russia and other CSTO members have not  taken, and do not intend to take, any actions that would be perceived  as closing the door to Yerevan," the minister said.
