NEW YORK (Kyodo) -- United States Steel Corp., the wholly owned unit of leading Japanese steelmaker Nippon Steel Corp., said Tuesday it will invest $11 billion domestically by the end of 2028 to drive growth under a new capital relationship.

U.S. Steel, which was acquired by Nippon Steel in June, envisions a roughly $14 billion multiyear investment target that will include significant capital inflows and "world-class" technology sharing.

The steelmaker also plans to "protect and create" more than 100,000 jobs by modernizing manufacturing processes and expanding research and development, among other steps.

The introduction of Nippon Steel's technological expertise, U.S. Steel said, has helped it come up with more than 200 initiatives to "drive operational efficiencies across all business segments."

Through a combination of capital investments and improved operational efficiencies, U.S. Steel aims to "unlock approximately $3 billion in value," it said.

"Even just a few months into our partnership with Nippon Steel, we're making great progress," U.S. Steel CEO Dave Burritt said in a statement.

"With world-class technology, extraordinary engineering capabilities and the best steel industry employees around the world, we are on a great path to forging the future of steelmaking in America," he said.

Takahiro Mori, who is both vice chairman of Nippon Steel and U.S. Steel's chairman, said in the statement that the two companies aim to strengthen the U.S. steel industry and expand job opportunities for Americans, while creating additional value for stakeholders.

The Japanese company completed its $14.1 billion acquisition of the struggling American steelmaker after the administration of President Donald Trump approved the deal, partly on the condition that it be given veto power over key management decisions.

Trump, who took office in January, had initially opposed the deal.
