Hyundai workers could return on Wednesday, Yonhap reports

By Cynthia Kim and Ted Hesson

SEOUL/WASHINGTON, Sept 7 (Reuters) - South Korea is

moving to pick up Korean workers following a raid at a Hyundai

Motor ( HYMLF ) manufacturing facility in the U.S. state of

Georgia last week, a presidential official for Seoul said on

Sunday as the Trump administration promised more raids on

businesses.

The negotiations to release about 300 South Koreans who were

detained have concluded and processing for their release from

custody is ongoing, South Korea's presidential office said late

on Sunday.

A chartered plane will be flown to bring them back as soon

as the processing by the two countries is complete, the office

said in a statement. It did not provide details of what

administrative steps are being taken.

The Yonhap news agency quoted South Korean Consul General in

Washington Cho Ki-joong as saying the workers will likely board

a plane on Wednesday.

Representatives for the Department of Homeland Security did not

respond to a request for comment, while White House border czar

Tom Homan separately vowed to expand immigration raids on

workplaces.

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

car battery plant in Ellabell, Georgia, on Thursday in the

largest single-site enforcement operation in the history of the

Department of Homeland Security's investigative operations.

U.S. President Donald Trump campaigned on making immigration a

pillar of his administration and has moved to ramp up

deportations nationwide since taking office in January. He has

also buttressed his economic plan in large part on wooing other

countries and foreign businesses to invest in the United States.

The roundup of 475 workers including about 300 South Korean

workers at the major Hyundai Motor ( HYMLF ) car battery plant under

construction caused shock and dismay in Seoul, as it came just

10 days after a summit between the U.S. and South Korean

presidents where they pledged closer business ties.

The South Korean government expressed regret about the

arrests and the public release of the footage showing a major

operation by U.S. immigration authorities involving armored

vehicles detaining the workers who were shackled and taken in.

The DHS earlier said the operation was executed under a

judicial search warrant over alleged unlawful employment

practices. A customs official has said many of those arrested

did not have proper immigration authorization to work at the

site.

AUTOS BIG PART OF SOUTH KOREAN INVESTMENT IN U.S.

South Korea's presidential chief of staff, Kang Hun-sik,

said on Sunday the government will seek ways to improve the visa

system of Korean workers traveling to the United States to

"prevent a similar incident."

DHS has said the arrested workers were barred from working

in the U.S. after crossing the border illegally or overstaying

visas.

Relations remain fraught between Washington and Seoul, a key

U.S. ally and investor, as both sides seek to hammer out final

details of their trade deal announced in July.

The trade deal includes a $350 billion fund to help Korean

companies enter the U.S. market, while Hyundai said it was

boosting its U.S. investments to $26 billion, including a

U.S.-based robotics facility.

Seoul is bracing for the impact on its auto sector of a

lower tariff on Japanese cars imported to the United States

while the duty for South Korean autos remains at 25%. Autos are

a major export industry for South Korea's trade-reliant

economy.

The site of the raid was a $4.3 billion project to produce

EV batteries, with Hyundai and LG Energy Solution

each holding a 50% stake as part of one of the largest economic

development projects in Georgia's history.

LG Energy Solution has suspended staff business trips to the

United States other than certain exceptional cases and will be

recalling those employees now in the United States.

Trump may visit South Korea in October for the gathering of

the Asia-Pacific Economic Cooperation event, CNN reported on

Saturday, citing three Trump administration officials.
