U.S. Steel and Japan’s Nippon Steel sued the United States government on Monday in a last-ditch attempt to revive their attempted merger after President Biden blocked it last week on the basis that the transaction posed a threat to national security.

Japanese companies needing to grow have sought out American deals. Experts say that will not change even after Biden’s rejection of Nippon Steel’s takeover attempt.

The companies condemned the president's decision and hinted at taking legal action, while U.S. Steel's CEO accused Biden of "political corruption."

The usually reticent ally is making it clear that it will not go quietly in its fight to overturn President Biden’s decision to block Nippon Steel’s $14.1 billion takeover bid of U.S. Steel, with Prime Minister Shigeru Ishiba warning this week that the rejection could have real consequences for the bilateral relationship,

By blocking a Japanese company’s takeover of U.S. Steel, President Joe Biden said he was protecting good jobs in the American heartland. He may be putting them at risk instead.

A government panel failed to reach consensus on national security risks of a proposal for Nippon Steel to purchase U.S. Steel, leaving the decision to the president.

President Joe Biden has rejected the nearly $15 billion proposed deal for Nippon Steel of Japan to purchase Pittsburgh-based U.S. Steel.

By David Shepardson, Tim Kelly, Andrea Shalal WASHINGTON/TOKYO (Reuters) -U.S. President Joe Biden blocked Nippon Steel's proposed $14.9 billion purchase of U.S. Steel on Friday, citing national security concerns,

The president said he was moving to protect national security in deciding the fate of the iconic Pennsylvania-based company, which became a contentious political issue in an election year.

U.S. President Joe Biden's decision to block Nippon Steel's $14.9 billion bid for U.S. Steel casts a shadow over Secretary of State Antony Blinken's visit to Japan on Tuesday for farewell meetings with Washington's most important ally in Asia.

US Secretary of State Antony Blinken insisted during a visit to Tokyo on Tuesday that ties with Japan were stronger than ever, days after President Joe Biden blocked Nippon Steel's takeover of US Steel.
