Nippon Steel has vowed to keep U.S. Steel American-led if its acquisition of the storied Pittsburgh, Pennsylvania, company is successful.

In a statement, the Japanese steelmaker promised that the majority of the board of directors and all members of the core senior management team at U.S. Steel would be U.S. citizens post-acquisition.

“The governance policy announced today has been developed to ensure the benefits of the transaction, while also maintaining U.S. Steel as an iconic American company,” Nippon Steel said in a statement.
