President Donald Trump said Monday that he would impose higher tariffs on India over its purchases of Russian oil, a notable escalation in the confrontation with the world’s most populous country.

“India is not only buying massive amounts of Russian Oil, they are then, for much of the Oil purchased, selling it on the Open Market for big profits,” Trump wrote on Truth Social. “They don’t care how many people in Ukraine are being killed by the Russian War Machine. Because of this, I will be substantially raising the Tariff paid by India to the USA.”
