MINSK, November 23. /TASS/. The main task of the Collective Security Treaty Organization (CSTO) is to preserve the solidarity and unity of all its member countries, Belarusian Foreign Minister Sergey Aleinik said before the beginning of the session of the CSTO Collective Security Council in Minsk.

"The most important thing is to preserve the solidarity and unity of all members of the organization. This is precisely what we actually demonstrated yesterday during the joint meeting of the Council of Foreign Ministers, [Council of] Defense Ministers, and secretaries of security councils of the CSTO member countries," he told the media.

Aleinik noted that at Wednesday’s meeting the parties "pointed to a very difficult geopolitical period, degradation of the Eurasian security architecture, devaluation of arms control and disarmament mechanisms, and hotbeds of tension along the western and southern borders and spheres and zones of CSTO responsibility."

"Under these conditions, of course, solidarity, cooperation, military-political interaction and political unity of the member countries come to the fore," Aleinik stressed.

"We are working for unity. We are looking for mutually acceptable solutions. Naturally, not all problems are solved at once," he acknowledged.

Alongside its 2023 chair, Belarus, the CSTO includes Armenia, Kazakhstan, Kyrgyzstan, Russia and Tajikistan.
