Nippon Steel's vice chairman plans to return to the United States this week for more talks over the proposed acquisition of U.S. Steel and would study selling some assets if necessary for the deal to go through.

Vice Chairman Takahiro Mori's visit so soon after a May 20-26 trip highlights the efforts Nippon Steel is taking to close the purchase amid growing regulatory scrutiny and political opposition. That includes resistance from President Joe Biden, who wants U.S. Steel to remain domestically owned, and objections from the powerful United Steelworkers (USW) union over fears of job losses.

The deal would give Nippon Steel greater access to the profitable U.S. market and further its long-term financial goals.
