She noted that the US welcomes the EU's decision to cap the price of Russian oil at $60 per barrel.
Blanchard added that the pricing mechanism was designed to be flexible on purpose.
“If the targets are not met, then the marginal price level can be adjusted over time to make sure we hit them,” TASS quoted her as saying.
Earlier, the Financial Times reported that the EU countries had reached an agreement on a price ceiling for Russian oil at $60.
The ambassadors of the EU countries officially confirmed the decision to introduce a ceiling on oil prices from Russia.
Russian Deputy Prime Minister Alexander Novak warned that Russia would not supply oil and oil products to countries that introduced energy price ceilings.
