India may pursue a case for resumption of oil supplies from sanction-hit Iran and Venezuela once the Joe Biden administration takes charge in the US.Sources in the Oil Ministry said that as a big importer of oil, India wanted to have a diversified market for crude and in this, if traditional markets like Iran and Venezuela are revived, it would only be for good.Though, sources said there would not be any change in relations with the US with change of regime there, limited talks could be initiated to see if the oil market can be expanded for big buyers so that competitive pricing is derived.Iran was India’s second largest oil supplier till sanctions by the West over its nuclear programme cut oil supplies.
