SEOUL (Reuters) -South Korea’s Hyundai Motor Group said on Monday that it has signed a memorandum of understanding with Posco Holdings for cooperation on its planned U.S. steel plant.

Posco will make an equity investment in Hyundai Motor Group’s steel factory project in Louisiana, the group said in a press release.

The steelmaker was also considering selling some of the steel to be produced from the factory. Production is slated to begin in 2029.

The South Korean automaker announced plans to invest $21 billion in the United States with President Donald Trump at the White House last month.

In a regulatory filing, Hyundai Steel said it would invest $5.8 billion along with Hyundai Motor Group to build a steel plant in Louisiana with an annual capacity of 2.7 million tonnes.

Trump slapped 25% tariffs on South Korea this month, which were later suspended for three months.
