The United States is preparing another round of sanctions against Russia's energy sector to increase pressure on Moscow if President Vladimir Putin rejects a peace deal with Ukraine, Bloomberg News reported on Wednesday, citing sources familiar with the matter.
The report said the United States is considering options including attacks on ships from Russia's so-called "shadow fleet" from tankers used to transport oil to Moscow, and against traders who facilitate the transactions.
The new measures could be announced as early as this week, the report said.
Treasury Secretary Scott Besant discussed the move when he met with a group of European ambassadors earlier this week, the report added.
