The heads of CSTO member states - Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan - will meet in the Belarusian capital, Minsk, to discuss current developments in its territory and in neighboring regions, including Afghanistan and Iran, ministry spokesman Mikhail Kamynin said.
Kamynin said the meeting would discuss a draft document on CSTO reform and further improvement of its activities.
Nikolai Bordyuzha, the secretary general of the post-Soviet collective security group, said in May that the CSTO, founded in 2002, would form its own peacekeeping forces, collective forces to tackle emergency situations and a number of auxiliary bodies to combat extremism and illegal migration.
Bordyuzha said it would be transformed "from a military-political organization into an organization that can promptly and effectively respond to modern threats and challenges."
