President Donald Trump and Russian counterpart Vladimir Putin discussed on Monday the war in Iran and prospects for peace in Ukraine, just hours after the Kremlin chief warned that a global energy crisis threatened the world economy.

The U.S. and Israeli attack on Iran triggered the biggest spike in oil prices since the turmoil following Russia’s 2022 invasion of Ukraine, as Gulf producers reduce output after the closure of the Strait of Hormuz.

The Kremlin said Trump called Putin, in the leaders’ first telephone call this year, and they discussed Russian ideas for a speedy end to the conflict in Iran, the military situation in Ukraine and the impact of Venezuela on the global oil market.

“I had a very good call with President Putin,” Trump told a press conference at his Florida golf club, adding that Putin wanted to be helpful on Iran.

“I said, ‘You could be more helpful by getting the Ukraine-Russia war over with. That will be more helpful.'”

The call came within hours of Putin’s remarks that the U.S.-Israeli war on Iran had triggered a global energy crisis, while cautioning that oil production dependent on transport through the Strait of Hormuz could soon come to a halt.

Putin said Russia, the world’s second-largest oil exporter and holder of its biggest natural gas reserves, was ready to work again with European customers if they wanted to return to long-term cooperation.

US SANCTIONS

Amid the turmoil on global energy markets, Trump’s administration is considering reducing oil sanctions on Russia, with an announcement possible as soon as Monday, according to three sources familiar with the planning.

The move would be intended to boost world supplies of oil following massive disruptions to Middle East shipments from the expanding conflict, but could also complicate U.S. efforts to deprive Russia of revenue for its war in Ukraine.

Talks could cover broad sanctions relief as well as more targeted options for certain countries, such as India, to buy Russian oil without fear of U.S. penalties, including tariffs, the sources told Reuters, speaking on condition of anonymity.

Last week, the United States allowed India to temporarily buy Russian crude oil already on tankers at sea, to help it cope with the cuts to Middle East supply.

Kremlin foreign policy aide Yuri Ushakov said the discussion with Trump was “very substantial” and “likely to have practical significance for further work between the two countries”.

Ushakov said Trump believed it was in the U.S. interest to see a “rapid end to the conflict in Ukraine with a ceasefire and a long-term settlement”.

The advance of Russian troops in Ukraine should prompt Kyiv to seek a negotiated end to the conflict, he added.
