South Korea and Japan are set for a showdown at the World Trade Organization's Geneva headquarters over Tokyo's export restrictions on Seoul.
They'll be holding talks on Friday attended by officials at the director level.
South Korea had sent a request for a bilateral consultation after lodging a complaint with the WTO last month.
According to WTO rules, both parties should hold their first consultation within 30 days of the original request.
In July, Tokyo imposed export restrictions to South Korea on three high-tech materials, which are crucial in the production of semiconductors and displays.
Seoul says the curbs violate the rules of the WTO and GATT.
