"The CSTO's 'Interaction-2017' exercises will be held in Armenia on October 9-13 within the framework of the joint operational-strategic exercise 'Combat Brotherhood-2017,'" the press service of the Armenian Defense Ministry said.
The statement added that staff talks for the necessary preparatory work will be held in Yerevan from June 27-30 with participation of representatives of CSTO Secretariat and the Joint Staff of the CSTO, interested ministries and departments of CSTO member states.
The CSTO was established in October 2002 as a regional intergovernmental alliance by Russia, Armenia, Kazakhstan, Kyrgyzstan, Tajikistan, and Belarus. The CSTO Charter stipulates the pledge of all member-states to abstain from the use of force and join other military alliances. Aggression against one signatory state equals aggression against all.
