WASHINGTON (Reuters) -A top aide to President Donald Trump on Sunday accused India of effectively financing Russia's war in Ukraine by purchasing oil from Moscow, after the U.S. leader escalated pressure on New Delhi to stop buying Russian oil.

U.S. President Donald Trump's India tariffs have shown Moscow's allies that he will follow through with his threat to impose secondary tariffs on countries that purchase Russian oil, though doubts remain about the practicalities of implementing them,

President Trump says India buys military equipment and oil from Russia, which enables Moscow’s war in Ukraine.
