CSTO is working on the participation of its peacekeepers in current UN operations, Secretary-General of the Collective Security Treaty Organization Stanislav Zasyan said, TASS reported.

His remarks came at the session of the UN Security Council.

According to him, the organization is ready to provide combined peacekeeping units staffed by the CSTO members.

AS he noted, the CSTO sees unprecedented tension near its western borders and hopes that the situation can be corrected.

"Unprecedented tension has grown in our western direction - the Eastern European region. The buildup of military units, military infrastructure and growing military activity that have continued close to the western borders of the CSTO member states over the recent years, combined with the unsettled problems in the east of Ukraine, have brought the situation to the brink of sliding into full-scale military actions," the secretary-general said.

"We hope very much that the parties to the process of negotiations will be able to find acceptable solutions to the problems and won’t allow military activities," Zas told a meeting of the UN Security Council on Wednesday.
