President Donald Trump says U.S. Steel will keep its headquarters in Pittsburgh as part of what he called a “partnership” between the American steelmaker and Japan-based Nippon Steel, which sought to buy it.

India's JSW Steel , the country's top steelmaker by market cap, reported a smaller-than-expected rise in fourth-quarter profit on Friday, hurt by weak steel prices.

Japan’s Nippon Steel has pitched a new American plant and billions of additional investments to clinch support for a deal.
