Japanese Foreign Minister Taro Kono said on Tuesday that Tokyo could not accept South Korea’s demands for additional measures regarding a 2015 bilateral agreement on the issue of Korean women forced to work in Japanese wartime brothels. The comments came after South Korean Foreign Minister Kang Kyung-wha said Seoul was not seeking to renegotiate the agreement, but that Tokyo needed to make further efforts to help the victims “regain honor and dignity and heal wounds in their hearts,” Reuters reports. Under the agreement, Japan apologized to victims and provided 1 billion yen ($8.8 million) to a fund to support them.
