Korea will raise the issue of Japan's wartime sexual enslavement of Asian women at this month's UN General Assembly in New York.

A Foreign Ministry official on Monday said the issue will be brought up but the way this will be done is still under review.

Historians say over 200,000 women, mostly Korean, were forced into sexual slavery by the Japanese Imperial Army during World War II.

It would not be the first time that the Korean government has brought the issue to the General Assembly's attention. Seoul is proposing to Tokyo an arbitration panel that would be tasked with resolving the decades-old dispute.
