President Donald Trump announced that India will stop purchasing Russian oil, calling it a major step in pressuring Vladimir Putin to end the war in Ukraine.

Trump said Indian Prime Minister Narendra Modi assured him the process is underway, though it will take some time to complete.

The move could ease U.S.-India tensions, which escalated after the U.S. imposed 50% tariffs on India over its Russian oil purchases this summer.

The announcement comes ahead of a potential Trump-Modi meeting at a Southeast Asian summit in Malaysia, Politico has reported.

Trump also indicated the U.S. might target China with tariffs if Europe acts similarly, urging Beijing to join India in boycotting Russian oil.
