Abbas Araghchi made the remarks in a post on his Instagram account, after he said he had separate meetings with Armenian Deputy Foreign Minister Vahan Kostanyan and Russia’s special envoy for the Caucasus Igor Khovaev in Tehran on Wednesday, during which the sides discussed international issues with the main focus on the political developments in the Caucasus region.

The top Iranian diplomat added that during the meetings, he “once again” emphasized that the Islamic Republic is highly sensitive regarding “any plan or project that would restrict transportation access or the interests of our country."

In his Wednesday meeting with Kostanyan, Araghchi warned that any peace deal containing plans to reopen blocked routes in the region must not alter the region’s geopolitics or disrupt other countries’ lines of communication.

The Iranian foreign minister underscored Tehran’s longstanding support for peace between Armenia and Azerbaijan and for reopening transport links with full respect for sovereignty and territorial integrity.

The Iranian minister was referring to a recent US-brokered peace deal between Armenia and Azerbaijan, under which a transport corridor linking Azerbaijan to its landlocked exclave Nakhchivan is to be established.

Under the deal signed in Washington on Friday, Armenia granted exclusive rights to the US to develop a corridor in its southern Syunik province, which borders Iran, to connect Azerbaijan to Nakhchivan.

Iran has for long opposed the idea, saying it would change the geopolitical order of the Southern Caucasus and would restrict Iran’s ability to use transport networks in the region.
