SEOUL, South Korea — The South Korean government announced on Saturday that it will not participate in a memorial event taking place near Japan’s Sado Island Gold Mines, citing undisclosed disagreements with Tokyo. This decision has reignited historical tensions related to the exploitation of Korean laborers forced to work at the mines during World War II.

According to a statement from South Korea’s Foreign Ministry, it was not feasible to resolve the disputes between the two nations prior to the memorial, which is scheduled for Sunday. Specific details regarding the nature of these disagreements were not disclosed.

Criticism emerged from certain South Koreans who expressed concerns over the government’s support for the memorial without obtaining a definite pledge from Japan to acknowledge the suffering of the Korean laborers. Additionally, there were objections regarding South Korea’s decision to cover the travel costs for the family members of Korean victims who were invited to the ceremony.

Meanwhile, South Korean President Yoon Suk Yeol is focused on fostering better ties with Japan after a period of strained relations, which stem from historical grievances. His administration is also committed to strengthening trilateral security cooperation with the United States, particularly in response to the threats posed by North Korea’s nuclear advancements.
