South Korean Foreign Minister Kang Kyung-wha said Tuesday the process of reaching a deal with Japan on "comfort women," who were forced to work in Japanese wartime military brothels, "lacked significantly" in communication with the victims.

Kang made the remark a day before the government of President Moon Jae-in was set to announce the results of its review of the December 2015 deal, which was hailed as a landmark agreement at the time but has since been seen in South Korea as deeply controversial.

According to the Yonhap news agency, Seoul plans to make its final decision on how to approach the agreement after hearing the opinions of victims and citizen groups.
