S.Korea to discuss Japan trade curbs with US

South Korea has sent a top presidential official to Washington to discuss Japan's stricter export curbs against the country.

The deputy chief of the presidential National Security Office, Kim Hyun-chong, arrived at an airport near Washington on Wednesday. He is an expert in trade negotiations.

Kim told reporters that he would visit the White House and Congress to discuss the Japanese measure. Analysts say he may ask the US to act as a mediator.

South Korea also plans to raise the matter at a bureau-chief-level economic meeting with the US in Washington on Thursday.

Kim Hee-sang from the South Korean foreign ministry is taking part.

Kim said, "The Japanese measure will be extremely detrimental for US industry. I came to the US to explain that."

Kim says the Japanese restrictions are a dangerous measure that will disrupt the international trade order.
