South Korea has reportedly rejected recent offers made by Japan to resolve the turbulent issue of Korean women who were forced to serve as sex slaves for Japanese soldiers during World War Two.

The government said offers including an apology from Prime Minister Yoshihiko Noda to President Lee Myung-bak and an apology from the Japanese ambassador to Seoul to surviving sex slave victims were insufficient proposals to resolve the issue.

The Japanese government also reportedly offered to directly compensate the victims, but that suggestion was also turned down by South Korea due to the proposal's insufficiency. Observers say it would be hard for Japan to directly provide compensation given it would have to assume legal responsibility for forcibly mobilizing the Korean sex slaves.

The South Korean government has repeatedly asked Japan to hold negotiations on the sexual slavery issue, following a ruling by the Constitutional Court that more diplomatic efforts are needed to address the matter.
