Allowing the merger to proceed would help both companies, bolster our relationship with an important ally, and strengthen the U.S. economy.

Nippon Steel , Japan's biggest steelmaker, said on Thursday its proposed acquisition of U.S. Steel fits with President Donald Trump's goal of a stronger United States as the leaders of the two allies prepared to meet.

Nippon Steel Corp. and United States Steel Corp. claimed former President Joe Biden unfairly prejudged their $14.1 billion merger and gave the companies no chance for feedback on a “sham” national security review before he blocked the deal.
