At least two vessels loaded with Russian oil bound for refiners in India have diverted to other destinations following new U.S. sanctions, trade sources said, and LSEG trade flows showed.

At least four oil tankers laden with Russian crude are waiting off India’s western coast, as the Asian country’s purchases of the commodity come under the spotlight amid pressure from the US and European Union.

India has bought a nearly constant flow of Russian oil for the past two years. Prices fluctuated, but each year’s sales have been worth approximately $275 billion. Iraq and Saudi Arabia, traditionally India’s biggest suppliers, have been pushed to the side.
