Hyundai's new EV and battery manufacturing facilities will be based in the southern “right to work” state, where labour unions are less prevalent and cannot require workers to join.

Biden, a Democrat, has described himself as the most pro-union president in history. But the deal, announced by Georgia's Republican governor, showed the compromises the president may have to make as he woos investment overseas.

"Hyundai and any company investing in the United States would benefit greatly from entering into partnerships with some of the most highly skilled, dedicated, and engaged workers in the world, anywhere you can find; and that is American union members," Biden said.

"Every venture to manufacture electric vehicles and electric vehicle batteries would be made stronger by a collective bargaining relationship with our unions."

The new investment brings its planned US total through 2025 to about $10 billion, above the $7.4 billion it announced last year.
