June 18 (Reuters) – Nippon Steel has seen positive results from efforts to improve operations at U.S. ​Steel, one year after ‌its acquisition, but is not yet satisfied with the pace of reforms, the Nikkei newspaper reported on Thursday, citing the ‌steelmaker’s ​vice chairman and ⁠executive vice president.

“We’re ⁠seeing improvements, but we’re not yet satisfied,” Nippon Steel’s Takahiro Mori told Nikkei in an interview.

Mori said ​Nippon Steel had identified 260 areas for improvement at U.S. ⁠Steel and was ⁠introducing its manufacturing know-how to ​improve production efficiency.

Neither U.S. Steel nor ​Nippon Steel immediately responded to Reuters ‌requests for comment.

Mori told Nikkei that the company continues to pursue plans to build new steelmaking ⁠facilities in the United States and is evaluating locations, while also assessing investments in ⁠Pennsylvania’s ‌Mon Valley Works that ⁠could increase because of inflation, ​equipment ‌requirements and environmental reviews.

Nippon ​Steel completed ⁠its acquisition of U.S. Steel last year following regulatory scrutiny and commitments tied to national security.
