Actress Song Hye-kyo has turned down a modeling offer from Mitsubishi Motors because of its involvement in Japanese atrocities in World War II.

Song's PR agency on Monday revealed that the Japanese carmaker offered Song a starring role in a campaign in China a month ago, but she turned it down.

Song rejected the offer because Mitsubishi used Korean slave labor during World War II and is being sued by the victims, the agency said.

Song is a hot property in Korea and abroad thanks to her role in the KBS hit series "Descendants of the Sun."

The star has funded the publication of pamphlets at Korean independence movement sites and museums in the U.S. together with Prof. Seo Kyoung-duk of Sungshin Women's University.
