Member states of the Collective Security Treaty Organization (CSTO), the Moscow-led security alliance of former-Soviet republics, signed an agreement on military contingent and cargo transportation, Serzh Sargsyan, the president of Armenia, said on Tuesday, TASS reports.

“An agreement was signed on cooperation in the sphere of transporting military contingent and moveable property as well as military-purpose products,” Sargsyan told journalists following the summit of the CSTO member states in Tajikistan.

The Armenian leader added that the CSTO members also decided to extend an agreement on the logistics and technical support of railways in the countries of the post-Soviet security bloc.

Member-states the Collective Security Treaty Organization (CSTO) have approved a decision on introducing rotation of the post of the secretary general, CSTO chief Nikolay Bordyuzha said on Tuesday.

“It was considered useful to switch in the future to the rotation system of the general secretary’s post. The heads of states set the task to devise a respective draft decision by December and introduce changes to the legal basis and the CSTO Charter, what we will do now,” Bordyuzha said.

The Collective Security Treaty was signed in 1992 and the organization itself was set up 10 years later. Russia, which held the presidency in the CSTO, passed the rotating chair this year to Tajikistan.

The CSTO, which comprises Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, Uzbekistan and Tajikistan, regularly holds military drills on the territories of its member states.
