President Donald Trump said Friday that Russia would supply diesel to the United States, a move that could ease pressure on fuel prices while complicating U.S. policy toward Moscow’s war in Ukraine. Trump said on social media that he reached the agreement with Russian President Vladimir Putin during a phone call. He described an initial shipment of more than 300,000 tons, followed by 500,000 tons in November and 1 million tons “immediately thereafter,” with another 3 million tons to follow “within a short period of time.” The White House did not immediately clarify who would pay for the fuel or when it would be available in the United States. It also did not say whether later deliveries would arrive before the Nov. 3 midterm elections. Trump said lower prices for farmers, ranchers and truckers were a priority. The announcement comes amid rising global energy prices following the war in Iran. The U.S. average price for diesel was $6.23 a gallon, according to AAA, after reaching a record $6.52 on Sept. 22. Diesel futures fell Friday after Trump’s announcement. The move appears to conflict with a sanctions law Trump signed last month. The measure targets Russian officials, banks and a fleet of tankers, bars new U.S. investment in Russia and directs the administration to impose tariffs of up to 100% on major importers of Russian oil or natural gas, subject to an exception for certain countries. The Treasury Department said Friday it was issuing a temporary license allowing Russian diesel already loaded onto tankers to be delivered to the global market without U.S. sanctions applying until April 2027. The department has issued other temporary authorizations for Russian fuel shipments since the war in Iran began, but the latest license lasts longer than the standard 30-day period. The United States has not imported Russian oil or gas since 2022, when the Biden administration banned those purchases after Russia invaded Ukraine, according to the Energy Information Administration. Russia, meanwhile, had barred diesel exports since July as refinery damage and domestic demand strained supplies. Deputy Prime Minister Alexander Novak said Russia would begin lifting those export restrictions ahead of schedule and could start shipments to the United States in October. Ukrainian President Volodymyr Zelenskyy criticized Trump’s announcement as a “weak decision” by U.S. partners. In a statement, he said the deal could help Russia prolong the war and accused Washington of treating Ukraine unfairly. Trump’s envoy Steve Witkoff and son-in-law Jared Kushner were meeting with Ukrainian officials about a proposal to end the conflict when Trump announced the arrangement. Putin’s office said the leaders discussed prospects for resolving the war in Ukraine, the situation around Iran and bilateral relations. It said Russia was ready to supply oil and petroleum products to U.S. and global markets. The announcement also casts uncertainty on whether the administration will enforce the new sanctions law as written. Rep. Don Beyer, a senior Democrat on the House Joint Economic Committee, called the move “infuriating” and said it amounted to lifting sanctions on Russian fossil fuels.
