President Moon Jae-in has pledged to revisit the deal, saying South Koreans can't accept it emotionally.

The probe result may likely point out that the deal does not properly reflect the voice of the victims and its terms and wording are inappropriate.

Based on the outcome, the Moon government is likely to announce its own decision on the agreement later, possibly after the 2018 PyeongChang Olympics set for February.

The developments are likely to put Seoul and Tokyo on a tightrope, as Japan has repeatedly called for Seoul's compliance with the deal.

The team operates directly under Foreign Minister Kang Kyung-wha and is headed by Oh Tai-kyu, a former progressive journalist who advised Moon on social issues as part of a presidential advisory group. It includes eight other experts on diplomacy, human rights and international law, as well as ministry officials.
