South Korean lawmaker summoned in probe into Unification Church ties amid Busan bid
Seoul — A South Korean lawmaker from the ruling Democratic Party, Jeon Jae-su, is set to be summoned by the government's joint investigative headquarters probing ties between politics and the Unification Church. The probe is led by Kim Tae-hoon, head of the Daejeon High Prosecutors’ Office, and Jeon is scheduled to appear at 10 a.m. on the 19th. The unit has broadened the inquiry by also summoning Jeon’s spouse as a referenced witness.
Prosecutors are examining allegations that Jeon received cash and valuables from the Unification Church in 2018. Specifically, investigators allege he accepted 20 million won in cash and a luxury watch worth about 10 million won. Jeon has denied the charges.

The joint investigative headquarters has already questioned most of the major figures tied to the case, excluding Jeon. In recent days, investigators visited Han Hak-ja Moon, the Unification Church’s president, while he was detained to hear his testimony, and they have interviewed former lawmakers Im Jong-seong and Kim Gu-hwan, as well as Jeong Won-ju, a former secretary-general of the church. Jeon Jae-su remains the only principal figure not yet questioned by the panel, according to court and law-enforcement briefings.
On the political front, Jeon registered as a candidate for Busan mayor on the 13th and publicly announced his bid. Busan, Korea’s second-largest city, hosts the nation’s busiest port and plays a crucial role in regional commerce and supply chains. The outcome of the Busan race can influence local business policy, shipping, and infrastructure priorities that affect both Korean and international trade.

The Unification Church has a long and controversial history in Korean politics, with past scrutiny over political influence and fundraising activities. The current probe into allegations of monetary favors linked to political figures underscores ongoing concerns in South Korea about the relationship between religion, money, and political power, a topic frequently watched by international observers given Seoul’s role in global markets and in the U.S.-South Korea alliance.
For U.S. readers, the case matters because South Korea’s political stability and policy direction affect the U.S.-led security framework, defense cost-sharing, and regional diplomacy. Local governance in Busan also matters for supply chains and trade routes that connect to American manufacturers and consumers, making developments in this investigation and the mayoral race relevant to markets and policy discussions beyond Korea.
