Japanese politicians have been threatening to take legal action over the South Korean Supreme Court's ruling... ordering a Japanese company to compensate workers forced to work for it with no pay during World War Two.
On wednesday, South Korea's Prime Minister expressed "deep regret" over those and other remarks he called "aggressive."
Lee Nak-yon said they were neither "reasonable" nor "wise," and that in a democracy like South Korea, the government cannot meddle in decisions by the judiciary.
The PM said the Supreme Court's decision did not deny the treaty signed by the two countries in 1965 on compensation, but only clarified its scope when it comes to individuals.
Lee criticized what he called an attempt to trigger a diplomatic dispute over the issue and urged a wise response from Japan's leaders.
