Nippon Steel shares rose on Monday after U.S. President Donald Trump approved its $14.9 billion bid for U.S. Steel, clearing a key hurdle in its 18-month pursuit and securing access to a vital market for its growth strategy.

Administration officials secured a deal that will give the president unusual influence over a private company, and could serve as a model for other deals.

Nippon Steel Corp. won conditional US approval for its $14.1 billion purchase of United States Steel Corp., capping a lengthy saga in a tie-up that will create one of the world’s largest steel companies.
