Steel baron, once India's richest person, slipped in the rankings as his ArcelorMittal, the world's biggest steelmaker, got hit by rising imports from China. While it eked out a net profit of $179 million in the latest quarter, Arcelor had reported a net loss of $1.1 billion on revenues of $79.3 billion for 2014 partly as a result of a $621 million writedown of its Chinese steelmaker, China Oriental. The company said it would close down 2 mills in South Africa and is looking to restructure in the U.S. Mittal remains bullish on his home country; in May Arcelor signed a joint venture with state-owned Steel Authority of India to make automotive steel.
