The U.S. government's ownership of a golden share in U.S. Steel will not block Nippon Steel from taking any management action that it deems appropriate, the Japanese steelmaker's CEO said on Thursday.

The agreement calls for Nippon Steel to invest roughly $11 billion across U.S. Steel’s domestic operations over the next three years, a move the companies say will protect and create more than 100,000 jobs.

Nippon Steel completes its purchase of U.S. Steel after more than a year and half of high-stakes negotiations and national security concerns.
