HARRISBURG, Pa. (AP) — Nippon Steel and U.S. Steel said Wednesday they have finalized their “historic partnership,” a deal that gives the U.S. government a say in some matters and comes a year-and-a-half after the Japanese company first proposed its nearly $15 billion buyout of the iconic American steelmaker.

Nippon Steel Corp. closed its $14.1 billion acquisition of United States Steel Corp., bringing an end to a bruising takeover battle that was embroiled in American politics for months until finally gaining support from US President Donald Trump.
