TEHRAN – Despite ups and downs in Iran and the Republic of Azerbaijan relations, the two countries' relations have entered a new, dynamic, and promising stage of development in recent years.

Azerbaijani-Iranian relations have deep historical roots. These peoples have lived side by side for centuries. The peoples of Iran and Azerbaijan belong to the Islamic world. Scientific, spiritual, and cultural ties have united these peoples throughout history. During the period from 2003 to 2018, Azerbaijani-Iranian relations in the course of their development went through several stages, in each of which bilateral relations have experienced ups and downs. However, since 2013, a new page has been opened in interstate relations, and Azerbaijani-Iranian relations have entered a new, dynamic, and promising stage of their development.

However, the participation of Azerbaijan Republic and Iran in the project of the international transport corridor "North-South", trilateral cooperation between Azerbaijan, Iran, and Russia, as well as between Azerbaijan, Iran, and Turkey, close ties between the political elites of our countries, as well as frequent meetings of representatives of Azerbaijan and Iran ensured a general improvement in Azerbaijani-Iranian relations at the present stage.

The transport corridor "North-South" plays an increasing role in bringing Russia, Azerbaijan, and Iran closer together, which contributes to the preservation of peace and security in the region. It is expected that a significant reduction in transport costs and transportation time from South Asia to Northern Europe will strengthen the geopolitical alliance and attract other countries to it, which will play an important role in the formation of a regional trade center and increase the non-oil revenues of Azerbaijan and Iran. The transport projects "North-South" and "East-West" create a favorable transport network for the countries of Central Asia and form the transit potential of Azerbaijan and Iran, the joint development of which is a priority for both countries.

After signing the Caspian Convention in 2018, new opportunities for cooperation have emerged, primarily in the Caspian. The International Baku Port, today, is making every effort to become a regional transport and logistics center of Eurasia. The construction of new sea gates continues in the Alat settlement. Azerbaijan has already fully commissioned the first phase of the seaport in Alat. Iran has also fortified its ports in the Caspian. Given the existing infrastructure, it can be argued that the delivery of goods will be cheaper compared to other means of maritime transport, and the Caspian Sea will become an important platform for freight and passenger traffic between the two countries.

However, soon new opportunities for deeper cooperation will open between Iran and Azerbaijan. The liberation of the cities of Zangilan and Jebrail, as well as the historic Khudaferin Bridge as a result of the Second Karabakh War, and most importantly, the restoration of full control over the 132-kilometer section of the Azerbaijani-Iranian border will strengthen economic ties between Azerbaijan and Iran.

Four years ago - during the visit of President Ilham Aliyev to Iran on February 23, 2016, an agreement was signed on cooperation between the governments of Azerbaijan and Iran in the field of continuing the construction of hydropower facilities and hydropower plants "Khudaferin" and "Giz Galaxy" on the Aras river, their operation and use of energy and water resources ". This agreement proclaims the principles of respect for Azerbaijan and Iran's sovereignty and territorial integrity, the same rights to water and energy resources of the «Khudaferin» and «Gyz Galasy» hydropower facilities. It also emphasizes the need to restore the territorial integrity of Azerbaijan in accordance with UN resolutions. In addition, the agreement reflects that the completion of the construction of hydropower plants and hydroelectric power plants, as well as the protection of water and energy resources at hydropower plants and hydroelectric power stations until the restoration of the territorial integrity of Azerbaijan, will be provided by Iran. This agreement provides Azerbaijan's access to the occupied territories and makes it possible to carry out economic activities there. The agreement once again emphasized the belonging of these territories to Azerbaijan and completely excluded Armenia's rights to them.

At that time, some political forces argued that the hydroelectric power plants on the Aras River, the construction of which was provided for by the agreement, would allegedly serve to strengthen the communication link between Iran and Armenia. The political forces, who understood absolutely nothing about this agreement's essence and strategic significance, presented it as if this document created conditions for the development of Armenian-Iranian cooperation.

Today, when Azerbaijan managed to fully restore the international border with Iran, it became clear once again that the political forces that criticized this agreement did not understand not only its political significance but also the processes of regional and global significance, including the growing authority, the military and political power of Azerbaijan. They were completely unable to analyze these processes and did not take into account the reality that the occupied Azerbaijani regions adjacent to the Iranian border would be liberated from the armed forces of Armenia. Here you can clearly see that in 2016 Iran and Azerbaijan agreed on the implementation of a very important agreement, which in the post-war period will give a great impetus to the socio-economic development of the region and will open up new opportunities between Iran and Azerbaijan in the implementation of infrastructure projects. An analysis of bilateral relations between Azerbaijan and Iran allows us to draw a general conclusion that at the present stage, Azerbaijani-Iranian relations are experiencing a new, dynamic, and promising stage in their development, which contributes to the strengthening of peace and good-neighborly cooperation in the region, the search for constructive answers to the challenges of the rapidly changing international situation. Now there is every reason to assert that after the end of the war in Karabakh, another new page will open in the relations between Iran and Azerbaijan in the post-war period. There is a lot of work ahead of both countries - Tehran and Baku have to fulfill their obligations to fulfill the agreement signed on February 23, 2016, in Iran.
