Last Friday, Iran and Russia formalized a major energy and nuclear cooperation agreement in Moscow, outlining plans for Russia to begin delivering natural gas to Iran and to finance the construction of a new nuclear power plant. Signed by Iran’s Oil Minister Mohsen Paknejad and Russia’s Energy Minister Sergei Tsivilev, the deal also includes a $4 billion commitment from Russia to develop seven Iranian oil fields. The agreement, which builds on a strategic cooperation treaty signed in January, aims to deepen economic ties between two heavily sanctioned states and strengthen Iran’s energy infrastructure and nuclear capacity.
The gas component of the agreement was reported by Iran’s state-run Shana News Agency. According to the announcement, deliveries will begin at around 2 billion cubic meters (bcm) annually, with a long-term goal of scaling up to 55 bcm—equivalent to the pre-closure capacity of the Nord Stream 1 pipeline. Gazprom, Russia’s state-controlled energy firm, is expected to assist in the construction of new pipeline infrastructure, though specific routes have not yet been finalized. While Iran possesses the world’s second-largest natural gas reserves, domestic underinvestment and sanctions have created supply gaps, especially during winter months. Paknejad described the cooperation as a “stabilizing shield” against sanctions-related disruptions, particularly those leading to increased use of low-grade fuels like Mazut.
The oil portion of the agreement expands on a 2022 memorandum between Gazprom and the National Iranian Oil Company, which included plans to develop fields such as South Pars. However, the lack of access to advanced equipment and materials due to international sanctions continues to challenge progress in this area.
The nuclear section of the deal involves Russian financing for a new 1,000-megawatt light-water reactor in Iran, supplementing the existing Bushehr nuclear facility built with Russian assistance in the 1990s. As with previous arrangements, Russia will provide the nuclear fuel and remove spent material to limit proliferation risks. However, concerns remain amid Iran’s continued breaches of the 2015 Joint Comprehensive Plan of Action (JCPOA), particularly its enrichment of uranium to 60%, well above the deal’s 3.67% threshold. Iran’s stockpile is also far beyond agreed limits, according to the International Atomic Energy Agency (IAEA).
U.S. officials have expressed unease about the deal, particularly given recent Russian offers to mediate on nuclear matters following a February request by President Trump. Critics argue such moves could weaken Western diplomatic leverage. The Biden-era “maximum pressure” sanctions remain in place, and the Trump administration has introduced new inspections and potential penalties for entities supporting Iran’s nuclear or military sectors.
Online reactions to the deal have been mixed. The hashtag #IranRussiaDeal gained traction with over 1.5 million views, with some users praising the agreement’s ambition, while others flagged logistical and economic hurdles, including Iran’s reduced energy investment and the high cost of building pipelines and reactors. Industry analysts also noted that many of the pledged projects depend on future approvals and funding flows that may be impacted by further geopolitical shifts.
While the agreement reflects deepening coordination between Tehran and Moscow, its implementation will face challenges due to sanctions, financing barriers, and infrastructure constraints. Still, the accord signals both nations’ intent to expand bilateral cooperation and navigate around Western isolation, with long-term implications for regional energy and security dynamics.
