SEOUL, Sept 6 (Reuters) - South Korean President Lee Jae

Myung ordered all-out efforts on Saturday to respond to the

arrests of hundreds of the nation's citizens in a U.S.

immigration raid on a Hyundai Motor ( HYMLF ) car battery

factory.

Foreign Minister Cho Hyun said the government has set up a

team to respond to Thursday's arrest of over 300 Koreans at the

facility, under construction in the southern state of Georgia,

and that he may go to Washington to meet with officials if

needed.

The arrest of some 475 workers at the plant near Savannah,

part of President Donald Trump's escalating crackdown on

immigrants, was the largest single-site enforcement operation in

the U.S. Department of Homeland Security's history.

The Trump administration and Seoul, a key Asian ally and

investor in the U.S., have been at odds over the details of a

trade deal that includes $350 billion of South Korean investment

in the United States.
