Russia’s envoy to Vienna, Mikhail Ulyanov, has publicly criticized a US demand to halt all uranium enrichment activities within Iran. Ulyanov characterized the request as “completely irrational,” signaling a strong disagreement with Washington’s approach to the ongoing negotiations surrounding Iran’s nuclear program. The statement was made on Sunday and reflects Moscow’s position on the matter. This criticism comes as international talks aim to revive the 2015 Joint Comprehensive Plan of Action (JCPOA), which limited Iran’s nuclear program in exchange for sanctions relief. The US has maintained a firm stance on restricting Iran’s enrichment capabilities as a key condition for returning to the agreement. Russia’s opposition to a complete ban suggests potential complications in reaching a renewed consensus. Ulyanov’s remarks highlight the diverging perspectives among key stakeholders in the negotiations.
