MOSCOW, June 3 (RIA Novosti) - The Collective Security Treaty Organization (CSTO) will conduct joint military exercises in August-September in Russia, Kazakhstan and Belarus, the Belarusian defense minister said on Wednesday.

The defense ministers of the post-Soviet security bloc comprising Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, Uzbekistan and Tajikistan held a regular meeting in Moscow on June 3.

"The joint drills will be held in Russia, Kazakhstan and Belarus to practice the deployment of CSTO's joint rapid-reaction force," Leonid Maltsev told reporters after the meeting.

He said the exercises in Belarus will also involve the Russia-Belarus joint military grouping created within the framework of the CSTO.

According to media reports, Russia is planning to build a strong military contingent in Central Asia within the CSTO comparable to NATO forces in Europe.

The new force will comprise large military units from five countries - Kazakhstan, Kyrgyzstan, Russia, Uzbekistan and Tajikistan.

Russia already has joint military contingents with Belarus and Armenia in as part of CSTO cooperation.
