South Korea steps up effort to get U.S. help in export row with Japan

SEOUL (Reuters) - South Korea has warned the United States of the potential damage from "undesirable" Japanese restrictions on exports of high-tech material to South Korea, as a trade row between the East Asian U.S. allies intensifies.

As South Korea sought U.S. help in the dispute, triggered by disagreement over the issue of compensation for South Koreans forced to work for Japanese firms during World War Two, it also took steps to limit the damage to its companies.

South Korea's ruling party announced that up to 300 billion won ($255 million) would be included in a supplementary budget to cope with Japan's curbs on exports of three materials, crucial for advanced consumer electronics, by speeding localization of their supply.

The ruling Democratic Party said about one-third of the proposed budget would be for supporting South Korean materials and equipment makers to help them get their products to market.

The East Asian neighbors share a bitter history dating to Japan's colonization of the Korean peninsula from 1910 to 1945.

Relations took a turn for the worse this week when Japan said it would tighten curbs on exports of the materials used to make chips and display panels because trust with South Korea had been broken over the forced labor dispute.

S&P Global Rating's Asia-Pacific chief economist Shaun Roache said the dispute was as unpredictable as the U.S.-China trade war and was likely to affect South Korea's growth.

The Japanese restrictions will affect companies such as Samsung Electronics Co Ltd <005930.KS> and SK Hynix Inc <000660.KS>, which supply chips to companies such as Apple Inc <AAPL.O>.

U.S.-SOUTH KOREAN CALL

South Korean Foreign Minister Kang Kyung-wha told U.S. Secretary of State Mike Pompeo in a phone call late on Wednesday that Japan's restrictions may not only damage South Korean companies, but could also disrupt the global supply chain and hurt U.S. firms.

Kang "expressed concern that this is undesirable in terms of friendly relations between South Korea and Japan and trilateral cooperation among South Korea, the U.S. and Japan," Kang's ministry said in a statement.

South Korea hoped Japan would withdraw the curbs and that the situation would not deteriorate further, it said.

Pompeo said he understood and they both agreed to strengthen communication between the three sides, it said.

The State Department said the two reaffirmed their commitment to the final, fully verified denuclearisation of North Korea and the importance of trilateral cooperation between the United States, Japan and South Korea.
