South Korea Prosecutors Question Spouse of Ruling-Party Lawmaker in Unification Church Cash-for-Politics Probe

Investigators from the Joint Investigation Headquarters, led by Kim Tae-hoon, the chief prosecutor of the Daejeon High Prosecutors Office, questioned the spouse of a South Korean lawmaker from the ruling party on Friday as part of a probe into alleged cash-for-politics linked to the Unification Church.

The inquiry centers on accusations that Democratic Party lawmaker Jeon Jae-su accepted 20 million won in cash and a watch worth about 10 million won from the Unification Church. The spouse, reported as a witness, was summoned to provide testimony about the money and gifts in question.

The probe follows a statement made last August by Yun Yong-ho, former head of the Unification Church World Headquarters, who told the Kim Keon-hee special prosecutor team that the church gave money to five politicians, including Jeon, during 2018 to 2020. The investigation team says Yun’s testimony suggests a link between the church and political fundraising.

Prosecutors believe Yun contacted Jeon to seek influence over the church’s long-standing goal of advancing a Korea–Japan undersea tunnel project. The scope of the inquiry has grown as other high-level church figures have been questioned.

In recent weeks, former lawmakers Im Jong-seung and Kim Kyu-hwan, among others associated with church networks, have been summoned. Attention is now on whether Jeon himself will be summoned for questioning as part of the ongoing investigation.

Beyond Korea, the case touches on broader concerns about the influence of religious or private groups on politics and policy. For the United States, which maintains a long-standing security alliance with South Korea, developments involving political fundraising, transparency, and governance can affect policy continuity, regulatory risk for businesses, and the stability of regional leadership decisions in a critical trade and technology corridor.

The Unification Church, a religious organization with a global footprint, has previously drawn scrutiny for its political connections. The current investigation illustrates the ongoing attention in Korea to how donor networks may intersect with legislative decision-making and major infrastructure proposals, including plans that could influence regional trade routes and security dynamics in East Asia. The investigation remains ongoing, with prosecutors expected to disclose further developments as interviews continue.
