A group of Chinese lawyers and experts are considering filing lawsuits against Japanese companies to seek compensation for victims of wartime forced labor, people involved in the plan said Wednesday.

The plan, if carried out, could further complicate efforts by the two countries to repair relations fraught with tension over territorial and historical issues.

Last year South Korean courts ordered several Japanese firms to pay damages over wartime forced labor. Tokyo maintains that all compensation issues were settled by a 1965 agreement normalizing bilateral ties.
