It has also emerged that, during their visit to the U.S., the two elderly victims of Japan's system of sex slavery also held closed-door interviews with officials from the White House and the State Department.
According to sources this week, Lee Ok-sun and Kang Il-chul met with the official last Wednesday and Thursday and asked the U.S. to take greater interest in trying to resolve the issue.
The White House reportedly said it would closely monitor the situation keeping in mind that the women don't have much time left.
The talks were the first face-to-face meetings between the former sex slaves and White House and State Department officials.
Korea will be hoping the discussions will bring about some changes to the U.S. government's policy on Japan's wartime atrocities.
