“Member states are making informal preparations in Tehran and other respective capitals. It should be noted that the corridor's route begins in the Persian Gulf in southern Iran and continues to Europe. The Digital Development and Transport Ministry stated that the results of the test run will be studied, the effectiveness of the route will be evaluated, and it will be possible to carry out rail freight through this corridor in the future. 

Iran, Azerbaijan, Georgia, Bulgaria, and other participants are currently negotiating the "Persian Gulf-Black Sea Corridor Agreement". South Asian countries will also have another route to the West through this corridor as part of the project,” – Safari said. 

The new transport corridor, which will connect the Persian Gulf with the Black Sea via Iran, Azerbaijan and Georgia, was put into operation in December 2021 in test mode. As part of the transit route, pilot freight has been sent from Iran for four months to deliver Iranian goods to Azerbaijan via the Astara border, as well as to Eastern European countries through the Black Sea ports of Georgia.
