NEW DELHI, Aug 14 (Reuters) - Indian state refiners have started making enquiries with trading firms about purchases of Russia's Urals crude oil as discounts widen, three people with knowledge of the matter said on Thursday, ahead of a high-profile meeting of U.S. and Russian leaders on Friday.
Indian state refiners - Indian Oil Corp IOC.NS, Hindustan Petroleum Corp HPCL.NS, Bharat Petroleum Corp BPCL.NS and Mangalore Refinery Petrochemical Ltd MRPL.NS - paused Russian oil purchases last month as discounts narrowed.
