MOSCOW, October 15 (RIA Novosti) - Russian President Dmitry Medvedev is arriving in Kazakhstan on a working visit Thursday, and will attend on Friday the final stage of a joint military exercise, the Kremlin said.

The Collective Rapid Reaction Force of the Collective Security Treaty Organization (CSTO) began the two-week exercise at Kazakhstan's Matybulak training grounds on October 2, with more than 7,000 personnel from Kazakhstan, Kyrgyzstan, Russia and Tajikistan taking part.

The CSTO comprises Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, Uzbekistan and Tajikistan.

According to the CSTO Secretariat, the exercise is aimed at practicing the deployment of the force in crisis situations on the territory of member states.

Analysts say the creation of a powerful military contingent in Central Asia reflects Moscow's drive to make the CSTO a pro-Russian military bloc, rivaling NATO forces in Europe.

Russia's security strategy until 2020, recently approved by Medvedev, envisions the CSTO as "a key mechanism to counter regional military challenges and threats."
