Japan and South Korea have begun exploring ways to resolve their long-running fight over compensation for wartime labor, with one option being the creation of a fund to provide money for economic cooperation, according to sources familiar with the bilateral relationship.

The idea being floated is for the South Korean government and companies in the country to set up a fund. Japanese companies would chip in money so it can be used under the name of economic cooperation, not as compensation for wartime labor, the sources said Monday.

The Japanese government does not plan to make monetary contributions, according to the sources.
