Nippon Steel is poised to expand its operations in the U.S. and India as it hunts for growth and protection from cheap Chinese exports after its bid for U.S. Steel was blocked by the White House, analysts say.

The suit, filed in the U.S. Court of Appeals for the District of Columbia, alleges that it was a political decision and violated the companies’ due process.

U.S. Steel and Nippon Steel said Monday they are suing the U.S. government over President Joe Biden’s blocking last week of the $14.1 billion sale of the iconic American company to the Japanese firm on national security grounds.
