Trump tells Zelenskyy to stop hitting Russian diesel plants

US President Donald Trump used a Sunday gaggle on the first tee at the Amgen Irish Open in Doonbeg to tell Ukrainian President Volodymyr Zelenskyy to stop striking Russian diesel refineries. "Mr. Zelenskyy has to do one thing. He has to stop knocking out diesel fuel in Russia," he said. "Let him go after targets, but not diesel fuel, because he's causing a shortage of diesel. This isn't done by the Middle East. This is done by what's happening with Russia and Ukraine."

He repeated the instruction hours later on Air Force One, flying back to Joint Base Andrews. Asked which war would end first, the Iran war or the Russia-Ukraine war, he said his problem with the latter was that "diesel fuel comes from Russia and the Russia plants are being hit by Ukraine." He added that he had already spoken to Zelenskyy. "There are plenty of other targets. Don't hit diesel fuel because that's hurting the world."

The average US retail diesel price crossed $6 a gallon over the weekend, a record. Some reports put the Sunday print at $6.20. Treasury Secretary Scott Bessent made a similar argument earlier this month on Fox News, saying Ukraine's decision to "blow up Russian energy assets and refine products" was putting upward pressure on prices alongside the Iran conflict.

Kyiv has spent recent months hitting refineries, depots and logistics nodes hundreds of kilometres inside Russia. The campaign is designed to raise the cost of the war for Moscow after more than four and a half years of fighting. Diesel and gasoline come off the same units, so a strike that knocks a plant offline cuts both products. Russia, normally the world's second-largest diesel exporter, has extended a ban on diesel exports through 30 September to protect the domestic market. Gasoline shortages inside Russia have been more visible than diesel shortages, but the export ban is what traders outside Russia feel.

Trump's framing treats the two wars as separable price shocks. The Middle East disruption is real: Saudi Arabia's East-West line is shut after drone hits, Hormuz traffic is constrained, and Houthis have tightened the Red Sea. Brent was above $107 on Monday. The president's claim is that the diesel spike in particular traces more to Ukrainian refinery strikes than to that Gulf and Red Sea squeeze. Energy analysts quoted in US and European coverage have refused that binary. They describe a refining system already stretched by two wars at once.

Ukraine did not issue an immediate public reply. The strikes have political value in Kyiv. They are one of the few tools that reach into the Russian interior without a large ground offensive, and they are popular with a public that has watched Russian missiles and drones hit Ukrainian cities for years. Asking Zelenskyy to spare diesel units is asking him to give up part of that campaign in the name of pump prices in the United States and Europe, five weeks before US midterm elections.

The request also sits next to a separate US track. Special envoy Steve Witkoff and Jared Kushner visited Moscow and Kyiv last week as Washington tried again to push a settlement. Trump has oscillated between pressure on Kyiv and pressure on Moscow. Telling Ukraine to stop hitting refineries while Russia continues long-range strikes on Ukrainian cities and infrastructure is a one-sided constraint. It is also a constraint that, if obeyed, would ease one of Moscow's domestic economic headaches.

Diesel matters for more than passenger cars. It moves freight, farm machinery and generators. A sustained price above $6 in the United States feeds into food distribution and construction costs just as the Federal Reserve weighs whether the energy shock is large enough to force a rate response before November. Trump has an interest in blaming a target he can telephone rather than a war he has not ended.

Russia's export ban runs only to the end of the month. If Ukrainian drones keep landing on distillation units, Moscow can extend it again. If Kyiv eases off under US pressure, some export barrels could return in October. That is the trade Trump is trying to force. Zelenskyy has to decide whether diesel plants are a military target he can still afford, or a political cost he now carries in Washington as well as in the air.

The remark does not bind Kyiv. It does change the conversation around the next package of US support. Officials who want more air defence and long-range munitions for Ukraine now have to answer a president who has named a class of targets he wants left alone. That is a narrower war than the one Ukraine has been fighting this summer, and it is the one Trump described from a golf course in County Clare.
