The Iranian army recently held massive military exercises near its border with Azerbaijan. These drills come against the backdrop of escalating disputes between the two neighbors after Baku imposed tariffs on Iranian trucks crossing the border and heading to Karabakh.
However, Azerbaijan President Ilham Aliyev considers the drills illegal and his country has voiced objections to Iran through various channels.
Iranian critics of the agreement that ended the second Karabakh war did not hide their concerns and claimed the deal would bring serious changes to their country’s border since the proposed corridor runs alongside it.
In the last stages of the war, Tehran was keen to appear as a neutral mediator between Azerbaijan and Armenia and offered to hold talks on more than one occasion
It is true that Iran has enjoyed strong relations with Armenia, but, on the other hand, it has not been able to place Azerbaijan within its regional sphere of influence.
Azerbaijan has maintained friendly relations with Tehran, because it relied on its airspace and territory to supply the Nakhchivan Autonomous Region, which lies between Iran, Armenia and Turkey.
