Russian President Vladimir Putin discussed with his Arminian counterpart Nikol Pashinyan the prospects of further cooperation within the Collective Security Treaty Organization (CSTO) over a phone call initiated by the Armenian side, Kremlin said Saturday.

"Prospects for further cooperation within the Collective Security Treaty Organization were discussed, taking into account current Armenia's chairmanship in the CSTO," the Kremlin said.

Kremlin also highlighted that President Putin briefed the Armenian president about the progress in the negotiations with the United States and its allies on Russia's security guarantees.

The two parties also discussed the implementation of agreements on the demarcation of the common borders between Armenia and Azerbaijan.

In detail, they took into consideration the agreements stipulated in the trilateral statements of the leaders of Armenia, Azerbaijan, and Russia, which took place on November 9, 2020, January 11, 2021, and November 26, 2021.

The issues on the table included those related to the elimination and demarcation of the Armenian-Azerbaijani border.

In a security council meeting, Armenian Prime Minister Nikol Pashinyan had accused Azerbaijan of "an aggression on Armenia's sovereign territory."

Azeri President Ilham Aliyev had accused the current US administration of taking a completely biased position toward Armenia.

The latest round of clashes between the two countries, which occurred in the Kalbajar area on the border, took the lives of one Azeri soldier and two Armenian soldiers.

Putin and Pashinyan also noted the feasibility of continuing the work of the Organization for Security and Cooperation in Europe's Minsk co-chairmanship consisting of Russia, the US, and France.
