South Korea, Japan fail to resolve growing trade dispute

South Korea and Japan on Friday failed to immediately resolve their dispute over Japanese export restrictions that could hurt South Korean technology companies, as Seoul called for an investigation by the United Nations or another international body.

Tokyo last week tightened the approval process for shipments of photoresists and other sensitive materials to South Korea, saying they can be exported only to trustworthy trading partners.

The move, which could affect South Korean manufacturers of semiconductors and display screens used in TVs and smartphones, has triggered a full-blown diplomatic dispute and further soured relations long troubled over Japan's brutal colonial rule of Korea before the end of World War II.

At their first meeting in Tokyo since the crisis erupted, Japanese officials told their South Korean counterparts that Tokyo saw weaknesses in Seoul's export controls.

They said that the trade curbs were not retaliation for South Korean court rulings that ordered Japanese firms to compensate aging South Korean plaintiffs for forced labor during World War II, according to a Japanese trade ministry official.

Lee Ho-hyeon, an official from South Korea's trade ministry, said Japanese officials cited inadequate bilateral discussions as a reason why their government tightened controls on high-tech exports to South Korea, but didn't clearly say whether Tokyo believes Seoul may have illegally transferred sensitive materials to North Korea.

Lee said South Korean officials countered by saying that Seoul has a stronger export control system than Tokyo's. The Japanese officials also reiterated that they won't negotiate over the trade curbs and said, without specifying, that there have been "inappropriate" cases regarding Japanese exports to South Korea.

When pressed by South Korean officials, the Japanese said the cases were unrelated to illegal shipments to a third country but refused to provide details, Lee said.

He said South Korean officials protested that Japan was providing only "very abstract" reasons for its stricter export controls.

"The positions still differ (between the two sides)," Lee said. "We did not see any willingness by Japan to change its measures from this meeting."
