Seoul Mayor Oh Se-hoon has issued several criticisms regarding domestic and foreign policy. In October, Oh criticized the central government and the ruling Democratic Party for failures in real estate policy. He argued that past decisions to cancel redevelopment zones led to a “housing supply cliff” and urged leaders to shift their policy direction to address high housing costs.

In November, Oh shifted his focus to foreign and security matters, claiming the ROK-US alliance is on “thin ice.” He suggested that statements from the Minister of National Defense and the Minister of Unification have undermined trust with Washington. He also raised concerns regarding economic and trade issues, including the need to manage US trade pressures and support promised US investments. Oh specifically cited recent comments from the US Ambassador to South Korea regarding “turbulence” in the bilateral relationship as evidence of uncertainty. He warned that delays in special legislation regarding US investments could hinder progress on nuclear-powered submarines and the revision of the ROK-US nuclear agreement.

Additionally, Oh has targeted the National Heritage Administration (NHA), accusing the agency of being the “biggest enemy of national heritage.” He alleged that the NHA is using the protection of the Jongmyo World Heritage site as a pretext to stall the Sewoon District 4 redevelopment project. Oh claimed the agency has imposed assessments lacking legal obligation, causing hardship for residents who have filed a 25 billion won damages lawsuit. He warned that such “unfounded administrative power trips” could lead to public backlash against UNESCO-related regulations, a term he called “UNESCOcide.”
