OTTAWA, June 21. /TASS/. The US is in talks with Canada and other allies around the world about curbing Russian energy revenues by imposing a price cap on Russian oil, US Treasury Secretary Janet Yellen said in Toronto on Monday.

"We are talking about price caps or a price exception that would enhance and strengthen recent and proposed energy restrictions by Europe, the United States, the UK and others, that would push down the price of Russian oil and depress [Russian President Vladimir] Putin's revenues, while allowing more oil supply to reach the global market," she said, Reuters reported.

Yellen said these moves shouldn’t adversely impact low-income and developing countries.

"We think a price exception is also an important way to prevent spillover effects to low income and developing countries that are struggling with high costs food and energy," she said.

Russian Deputy Prime Minister Alexander Novak said earlier that Russia planned to restore its oil production as much as possible by the end of June, following a slump in March and April amid sanctions. He conceded that production could decline to 480-500 mln tons in 2022 from 524 mln tons a year before. Russian Finance Minister Anton Siluanov has said Russia could lose up to 17% og oil production in 2022 due to sanctions.
