Seoul says Tokyo's re-examination of the 1993 Kono Statement, which is its first official acknowledgement of its use of sexual slavery during World War II, is an incomprehensible act.
When Japan announced its review of the statement,.. it also disclosed related documents.
Foreign ministry spokesperson Noh Kwang-il expressed strong disapproval of the act, saying that Japan's unilateral decision to disclose such documents is against standard diplomatic practice.
He added that Japan's coercion of women into sexual slavery has already been verified through investigations by the international society as well as UN reports, and thus, a re-examination on the issue, goes against common sense.
The move by Japan has also raised eyebrows outside of Korea.
A New York Times editorial titled "Japan's Historical Blinders" said Japanese nationalists will now use the results of the re-examination to retract its previous apology.
It added the country cannot be seen as trying to rewrite its past,.. and that the current actions were interfering with its efforts to play a leading role in the region.
And that certainly seems to be the case.
China, like Korea, also lashed out against Japan's latest move.
"Japan's "alleged investigation" exposes its true intentions of refusing to face up to history. It's even attempting to whitewash or deny the true intentions of its crimes during invasion."
Historians say up to 200-thousand women, mostly from Korea and China, were forced to serve in military brothels during World War II.
