WASHINGTON, Sept 7 (Reuters) -

President

Donald Trump

said on Sunday that foreign companies need to hire and

train American workers and respect immigration laws, following a

raid

at a Hyundai Motor ( HYMLF ) manufacturing facility

in the U.S. state of Georgia last week.

South Korea is moving to

pick up

some 300 South Koreans who were detained after the raid.

U.S. federal agents arrested about 475 workers at Hyundai's car

battery plant in Ellabell, Georgia, on Thursday.

"Following the Immigration Enforcement Operation on the

Hyundai Battery Plant in Georgia, I am hereby calling on all

Foreign Companies investing in the United States to please

respect our Nation's Immigration Laws," Trump wrote on Truth

Social.

"Your Investments are welcome, and we encourage you to

LEGALLY bring your very smart people, with great technical

talent, to build World Class products, and we will make it

quickly and legally possible for you to do so. What we ask in

return is that you hire and train American Workers."

Trump made the post shortly after telling reporters he

would look at what happened but that the incident had not harmed

his relationship with South Korea.

He also floated the idea that he would look at the

possibility of some foreign manufacturing experts being allowed

into the country to help train American workers.

The South Korean government has expressed regret about the

arrests and the release of the footage showing the operation

involving armored vehicles detaining the workers who were

shackled and taken in.
