SEOUL, South Korea (AP) — 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.
