Washington issued a host of fresh sanctions targeting what it calls the “logistics network” between Iran and Russia as the two countries move to enhance their relations.

The US State Department on Friday noted two Iranian shipping companies, a port operator and a marine service provider to its new sanctions list, continuing its unjust campaign against the Iranian nation.

The department added they were part of the "logistics network" between Moscow and Tehran.

The targets included Khazar Sea Shipping Line, and Nasim Bahr Kish, two Iranian shipping companies, and Grand Sea LLC, a maritime service provider in Makhachkala, Russia.

The sanctions also include the entities related to the recent agreement between Iran and Russia to build a railway section of the North-South Corridor.

The Iran-Russia relations have angered the US. That includes a recent agreement between Iran and Russia on the construction of a railroad section that connects southern Asia to northern Europe.

The US said it’s deeply concerned by any move to go around sanctions.

Tehran has slammed Washington's sanctions, saying that the Rasht-Astara railway project is part of its neighbor-oriented strategy, which is based on cooperation for security, development, and common prosperity.

Iran and Russia this week signed an agreement on the construction of the Rasht-Astara railway, a strategic transport corridor that connects the existing railways of the two countries and Azerbaijan.
