SOUTH KOREA said yesterday it will dissolve a foundation funded by Japan to compensate South Korean women who were forced to work in Japan’s World War II military brothels.

The widely expected decision, if carried out, would effectively kill a controversial 2015 agreement to settle a decades-long impasse over the sexual slavery issue and threatens to aggravate a bitter diplomatic feud between the Asian U.S. allies over history.

Japanese Foreign Minister Taro Kono criticized South Korea’s decision to shut down the foundation, saying that Seoul would violate the “most basic rule to live in the international society” by walking back on the deal. Japanese Vice Foreign Minister Takeo Akiba summoned South Korean Ambassador to Japan Lee Su-hoon to the ministry to lodge a protest.

“The announcement is problematic and unacceptable,” said Kono, urging Seoul to stick with the agreement signed under its previous government. South Korea’s Foreign Ministry couldn’t immediately confirm Kono’s comments that Ambassador Lee told Japanese officials Seoul doesn’t plan to scrap or renegotiate the agreement.

Seoul’s Ministry of Gender Equality and Family said it will take legal steps to dissolve the foundation, a process ministry officials said could take months. Lee Nam-hoon, an official from the gender equality ministry, said Seoul’s Foreign Ministry plans to consult with Tokyo on what to do with the 1 billion yen (US$8.8 million) Japan gave to the foundation that was formally launched in July 2016.

“After considering diverse opinions over the ‘Reconciliation and Healing Foundation’ based on victim-centric principles, we have decided to push for the dissolution of the foundation,” Gender Equality Minister Jin Sun Mee said in a statement. She said the ministry will continue to push policies to “restore the honor and dignity” of the sexual slavery victims.

Historians say tens of thousands of women from around Asia, many of them Korean, were sent to front-line military brothels to provide sex to Japanese soldiers.

Liberal South Korean President Moon Jae-in, who has been a harsh critic of the 2015 deal reached under his conservative predecessor, told Japanese Prime Minister Shinzo Abe during a meeting in September that the foundation was failing to function properly because of strong opposition by the victims and public.

South Korea and Japan are already at odds over a ruling by Seoul’s Supreme Court last month that a major Japanese steelmaker should compensate four South Koreans for forced labor during Japan’s colonial rule of the Korean Peninsula before the end of World War II.

Abe said Tokyo will respond “resolutely” to the ruling, which he described as a violation of a 1965 treaty between Seoul and Tokyo that restored diplomatic ties and was accompanied by more than US$800 million in economic aid and loans from Tokyo to Seoul. (SD-Agencies)
