United States — Office of Foreign Assets Control & Russia

United States — Office of Foreign Assets Control: The U.S. United States — Office of Foreign Assets Control (OFAC) imposed sanctions on Russian oil producers like Rosneft and Lukoil, which directly caused Indian refiners to cut or halt imports from these entities.

Russia: Russia experienced a reduction in fossil fuel export revenues from India in December 2025, as India's imports decreased. This is a direct consequence of U.S. sanctions and a shift in buying patterns by major Indian refiners.

United States — Office of Foreign Assets Control: The United States — Office of Foreign Assets Control issued warnings to financial institutions and ships regarding sanctions risks associated with importing Iranian oil and making 'toll' payments for passage through the Strait of Hormuz.

Russia: Russia, a key backer of Iran, hosted Iran's foreign minister for discussions on the war, though its specific assistance in the current negotiations remains unclear.
