In what could be a mega-deal between two corporate behemoths, Saudi Aramco, which is the world’s most profitable company in history, is apparently in “serious discussions” to acquire up to 25% in the refining and petrochemicals businesses of Reliance Industries Ltd, India’s largest company. Saudi Aramco, which is also the world’s largest oil exporter, showed interest in Reliance about four months ago, talks only gathered momentum following the visit of Saudi crown prince Mohammed bin Salman to India in February, during which he met RIL chairman and India’s richest man, Mukesh Ambani.
