Union leaders are spreading misinformation about Nippon Steel’s proposed $14.9 billion purchase of U.S. Steel, Nippon Steel Vice Chairman Takahiro Mori said on Monday.

“There is a lot of misinformation circulating about the Nippon Steel-U.S. Steel partnership and what it means for you,” Mori said in an open letter addressed to workers represented by United Steelworkers (USW) as he visits Pittsburgh to meet with key stakeholders this week.

“Said plainly, our commitments are about protecting and growing U.S. Steel and transforming its facilities so that they can be around for the next generation,” Mori added.
