According to the agency, Yellen, at a meeting with a colleague, stressed "the need to introduce a price ceiling system for Russian crude oil" and demanded South Korea's participation in the mechanism.
"Crude oil price cap should be effectively designed to help stabilize world oil prices and consumer prices," said the South Korean minister.
Earlier, the US Secretary of the Treasury announced the possibility of an increase in oil prices in the event that a price cap on Russian oil is not introduced.
She also said that the United States and its allies have not yet decided what kind of restrictions on the price of oil from Russia to impose, but take into account that the country must maintain the ability to produce and export oil.
The Russian Foreign Ministry warned that the anti-market plans of the G7 countries to set a price ceiling for Russian oil could lead to an increase in prices for it.
According to analysts at the American bank JPMorgan Chase & Co., if the G7 countries introduce a price limit for Russian raw materials, oil could rise in price to $380 per barrel.
