"There is a working discussion on going on this issue. A final decision is expected from the [CSTO] leaders on Monday. They are currently discussing several options," Ushakov told a press briefing.
He added that the position of the CSTO secretary-general has been made rotational, following the order of Russian alphabet, meaning an Armenian representative is expected to become the new CSTO chief.
The CSTO is a Russia-led intergovernmental military alliance, devised as a counterweight to NATO. The treaty, signed in 1992, currently has six members — all post-Soviet states — namely Russia, Armenia, Belarus, Kazakhstan, Kyrgyzstan and Tajikistan.
During the September CSTO summit, the six countries considered the election of a new secretary general to lead the organization, but long-standing acting CSTO chief Nikolai Bordyuzha, who has headed the alliance since 2003, has until now remained in office.
