South Korea suggested Tuesday it may break off talks with Japan at the World Trade Organization aimed at settling their dispute over Tokyo's export restrictions.

"We will not have talks for the sake of talks," South Korean chief negotiator Chung Hae-kwan told reporters after holding a second round of negotiations with Japan at the Geneva-based organization following Seoul's filing of a complaint with the body in September.

The meeting of more than six hours took place as part of dispute-settlement procedures under WTO rules. Chung said South Korea will conduct a review of what steps to take next, "including requesting the establishment of a panel."
