Russian President Vladimir Putin and his Iranian counterpart Ebrahim Raisi have taken part in a signing ceremony, via video link, for an agreement on the construction of a rail line between the Iranian cities of Rasht and Astara, the Kremlin press service reported on Wednesday.

The railroad linking the two cities is part of the International North South Transport Corridor (INSTC), a 7,200-kilometer multi-mode transit system that connects ship, rail, and road routes for moving cargo between India, Iran, Azerbaijan, Russia, Central Asia, and Europe, reports RT.

"The unique North-South transport artery, of which the Rasht-Astara railway will become a part, will help to significantly diversify global traffic flows. Transportation along the new corridor will have significant competitive advantages," the Russian president said. Putin added that the route will substantially cut travel times and costs, and help develop new logistics chains.

The 162-kilometer railway will connect the city of Rasht, near the Caspian Sea, to Astara on the border with Azerbaijan. Once completed, it will allow the transport of cargo from the Persian Gulf to the Finnish capital, Helsinki, via the Russian city of Saint Petersburg.

Putin also noted that the new rail section will make a tangible contribution to ensuring global food security.

"The new highway is intended to be used, among other things, for the transportation of food and other products of the agro-industrial complex, which will be intended both for consumers in Iran and for the countries of the Persian Gulf and Africa," the Russian president explained.

Analysts have said the North-South corridor could become a safe alternative to the Suez Canal to protect trade flows from geopolitical fallout. Existing transport infrastructure has been historically focused on the East-West connection, but new routes are gaining prominence due to global shifts in world markets towards China, South-East Asia and the Persian Gulf.
