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.

Nippon Steel, whose multibillion-dollar proposal to buy struggling US Steel was blocked by President Joe Biden last week, says it is considering taking legal action against the US government.
