There will be no special treatment for Budapest, which has asked to be exempt from sanctions on Russian oil, the US president has said

US President Donald Trump has dismissed Prime Minister Viktor Orban's request to exempt Hungary from sanctions on Russian oil.

Orban said in an interview with Kossuth Radio on Friday he will try to persuade Trump during his upcoming visit to Washington to grant Hungary relief from the sanctions on Russian energy companies Rosneft and Lukoil, which supply oil to Central Europe.

The US blacklisted the two companies last week, alleging a lack of commitment by Moscow to the Ukraine peace process. Hungary has repeatedly stated that Russian oil and gas are vital to its energy security.

Questioned by journalists aboard Air Force One later in the day, Trump said Orban "has asked for an exemption, but we have not granted one."

"He is a friend of mine," he added, while suggesting that the journalists move on to other questions.

Orban told Kossuth Radio that, as a landlocked country, Hungary has no viable alternatives to Russian oil, and that replacing it would push the nation toward an economic crisis.

"We have to make the Americans understand this peculiar situation... if we want them to allow exemptions from the American sanctions against Russia," he stated.

The Hungarian prime minister said he would bring a "large delegation" of ministers, economic officials, and security advisers to Washington on November 7 in order to finalize an economic cooperation package with the US. He stressed, however, that any deal would depend on continued access to Russian oil and gas.

Hungary, which has maintained a neutral stance on the Ukraine conflict, is also facing growing pressure within the EU to reduce its reliance on Russian energy, as the bloc plans to phase out oil and gas imports from the country by 2028.

Orban, a key Trump ally in the EU, visited the US several times during last year's presidential campaign to support his candidacy. In recent months, he has praised the US president's efforts to stop the Russia-Ukraine conflict.

President Vladimir Putin earlier described the US sanctions on Russian oil companies as an "unfriendly move," but said they would not have a significant impact on the economy.
