On May 13, Acting Minister of Foreign Affairs of Armenia Ara Aivazian held a phone conversation with CSTO Secretary General Stanislav Zas.

Acting Minister Aivazian presented to Secretary General Zas the situation resulting from the recent incident on the state border of Armenia on May 12. Ara Aivazian considered inadmissible the attempts of Azerbaijan to encroach on the sovereign territory of the Republic of Armenia- the CSTO member, noting that it is also a serious threat towards regional security and stability.

The interlocutors exchanged views on the application of the provisions of the Collective Security Treaty and the tools provided by the CSTO Charter in such situations.
