Most important motive for Iran`s activity in South Caucasus is to  strengthen presence of Turkey - expert 

ArmInfo.The most important motive for Iran's activity in the South Caucasus is to strengthen the  presence of Turkey, a NATO member country, in the region. 

Iranologist Vardan Voskanyan wrote about this on his Facebook page.  As justification for his words, the expert cited recent statements by  the new head of the IRI MFA Abbas Araghchi that the Caucasus region  is of geopolitical and strategic importance for Iran. "Historical,  cultural and geographical proximity has doubled the importance of  expanding ties with the countries of this region," the head of the  Iranian MFA said earlier.

"The statements of the Iranian Foreign Minister once again prove that  the South Caucasus is a zone of primary interest and importance in  the foreign policy agenda of official Tehran, where Iran will work  with redoubled efforts," the Iranologist is sure, adding that this  was largely facilitated by the active involvement of Turkey in the  affairs of the region, which brought additional challenges not only  to Armenia, but also to Iran. This is why Armenian-Iranian  cooperation can be very effective in building up multilateral  cooperation, which can and should take the form of a strategic  alliance. "Armenian-Iranian historical and cultural ties are  traditionally ancient, and the border of peace between Armenia and  Iran is one of the oldest borders that have ever existed between the  two countries," Voskanyan emphasized.
