Hyundai chief executive José Muñoz said on Wednesday that the White House phoned him personally to apologise for a massive immigration raid at a factory in the US state of Georgia.

Speaking at a conference of business leaders in Singapore, Mr Muñoz said the governor of Georgia had also called him and said “I don’t know what happened, this is not state jurisdiction.”

In September, more than 300 South Korean workers were detained in a raid at a battery plant operated by Hyundai and electronics giant LG, raising tensions between Washington and Seoul.

The BBC has contacted the White House and the governor of Georgia for comment.

During the raid, workers were forced to sit on the floor of the factory as officers shackled their legs in scenes that sparked outrage in South Korea.

The workers were held in detention for more than a week before being flown home after the South Korean government held urgent talks with the US.

The company warned in September that the raid would delay the plant’s opening due to labour shortages.

Mr Muñoz said during a panel discussion at the Bloomberg New Economy Forum that he believed that someone had “made a phone call and made it look like there were illegal immigrants” at the plant.

“That’s absolutely not the case,” said Mr Muñoz.

The raid was “a bad surprise” but the company remained committed to manufacturing in the US, he added.

US President Donald Trump has previously said that he was “very much opposed” to the raid.

Trump said at the time that the US had an “understanding” with the world on the need to bring in experts to set up specialised facilities and train local workers.

Despite the raid increasing tensions between the US and South Korea, the two countries announced in October that they had reached a broad trade deal.

Under the agreement, the two sides reduced reciprocal tariffs from 25% to 15%, while South Korea said it would invest $350bn (£266.5bn) in the US.
