Indian officials have said they would keep purchasing oil from Russia despite the threat of penalties that U.S. President Donald Trump said he would impose, the New York Times reported on Saturday.

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,

Trump has threatened 100 per cent tariffs on countries that buy Russian oil unless Moscow reaches a major peace deal with Ukraine.
