President Donald Trump has indicated that the US may not impose secondary tariffs on countries continuing to procure Russia crude oil.

There were apprehensions that additional secondary tariffs would have hit India in case the US decided to enforce them.

"Well, he (Russian President Vladimir Putin) lost an oil client, so to speak, which is India, which was doing about 40 per cent of the oil. China, as you know, is doing a lot and if I did what's called a secondary sanction, or a secondary tariff, it would be very devastating from their standpoint. If I have to do it, I'll do it. Maybe I won't have to do it," Trump said on Friday.
