GENEVA (Sputnik) — CSTO is a military bloc comprising six ex-Soviet states — Russia, Armenia, Belarus, Kazakhstan, Kyrgyzstan and Tajikistan.
"These issues are not on CSTO current agenda," Semerikov told reporters adding that Russia alone is quite successful in accomplishing all tasks in anti-terrorism fight in Syria.
Russia launched airstrikes against terrorist groups in Syria in September 2015 at the request of Syrian President Bashar Assad. On March 14, Russian President Vladimir Putin ordered to withdraw most of Russia's military contingent from Syria after objectives of the operation had been accomplished.
