An additional 2,091 South Koreans have been confirmed as victims of forced labor by imperial Japan who ruled the Korean Peninsula as a colony during the first half of the 20th century, the Seoul government said Thursday.

The new victims were discovered after new records were found kept at the South Korean Embassy in June, 2013. Out of the 5,157 names listed on the records, 2,091 were immediately confirmed as bona-fide victims of Japan's forced labor.

The records were compiled in 1953 under the Rhee Syng-man administration following South Korea's independence from Japan's 1910-45 colonial rule.

The confirmation comes as some local labor victims are awaiting a court ruling in a landmark damage suit filed against some Japanese companies that were involved in the colonial-era forced labor.

Officials said a court decision in favor of the South Korean labor victims may trigger a flurry of economic and diplomatic issues to be settled between the neighbors.

The government estimates that up to 7,820,000 Koreans had been forced into hard labor under the brutal colonial rule of Japan.

Only 600,000 so far have been officially recognized as labor victims entitled to state financial support.

Japan has long declared that all liabilities toward the South Korean government and individual victims were settled through the 1965 treaty between the two countries, which restored diplomatic ties. In the treaty, Japan provided a large sum of money to the South Korean government. (Yonhap)
