Indian refineries halt Russian oil purchases after Trump threats India's state-owned oil refineries stopped importing Russian oil after US President Donald Trump threatened 100% tariffs for cooperation with Russia. The suspension began this week, four industry sources told Reuters. Indian Oil Corp, the largest oil company operating 10 of India's 20 refineries with a 60-million-ton annual capacity, has ceased purchasing Russian oil. Hindustan Petroleum, Bharat Petroleum, and Mangalore Refinery Petrochemical have also halted imports, sources said. Refineries are seeking alternatives on the spot market, buying from OPEC countries in the Middle East and West Africa. Private refineries Reliance Industries and Nayara Energy, the largest buyers of Russian oil in India, are affected, with Nayara hit by the EU's 18th sanctions package, Reuters reports.
