Iran and Russia are working together on a very big nuclear power project, like building a huge shared power plant. The story says they are also teaming up on trains, gas, and medicine made with nuclear science.
Analysis
Nuclear cooperation
Iran's ambassador to Russia, Kazem Jalali, said the Hormoz project is now being implemented and described it as the largest nuclear project in Iran. According to his remarks at an online conference in Moscow, the project is backed by a $25 billion investment and is being developed by Iran's private sector with Russia's state nuclear corporation, Rosatom.
Jalali also pointed to the Bushehr Nuclear Power Plant as another major area of cooperation. He said Bushehr is already operating, while its second and third units are still under construction. He presented these projects as part of broader peaceful nuclear energy cooperation between Tehran and Moscow.
Wider ties
Beyond nuclear power, Jalali highlighted the International North-South Transport Corridor as a key route for the region. He said cargo capacity on different parts of the corridor is expanding and that both countries are working on major infrastructure, including the Rasht-Astara railway.
He also mentioned the transit of Russian gas through Iran and growing trade with Eurasian countries as fast-developing areas of cooperation. On the scientific side, he said Iran produces around 70 radiopharmaceutical products and stressed the role of nuclear technology in medicine and research.
The article frames the relationship as a broad strategic partnership covering energy, transport, advanced technology and economic development, with Iran also valuing Russia's political support in international forums.
Key points
- Iran's ambassador said the Hormoz project is the largest nuclear project in the country and is being developed with Rosatom.
- He said the project has $25 billion in backing and is part of peaceful nuclear energy cooperation.
- Bushehr is operating, while its second and third units are still under construction.
- The envoy also linked the relationship to the INSTC, the Rasht-Astara railway, gas transit and Eurasian trade.
- He said Iran produces about 70 radiopharmaceutical products and stressed medical and research uses of nuclear technology.
If the projects stay on track, Iran could add more nuclear power capacity and expand useful civilian applications like radiopharmaceuticals. Better transport links and energy cooperation could also strengthen trade between Iran, Russia and nearby countries.
The article does not say when the projects will finish, and large nuclear and infrastructure plans can stall if financing, construction or politics get in the way. The heavy focus on Russia also leaves Iran exposed if the partnership slows or external pressure rises.
