Oh Se-hoon

Oh was involved with the Seoul Foundation for Arts and Culture, participating in a celebration video for the organization alongside foundation chairman Park Bum-Shin and Seoul Arts Director Ahn Eun-Mi.[4][5]

Dongdaemun Design Plaza was constructed during his tenure.[6]

When asked about the Seoul Queer Culture Festival during the 2021 Seoul mayoral race, Oh has stated that, "In a broader spectrum, the principle is that the rights of minorities, including sexual minorities, must be protected and there should be no discrimination." He further went on to say, "I think the debate was on the queer festival being held in the central area near City Hall and Gwanghwamun Plaza, and the city of Seoul has a special committee to make a decision, and there are rules to that as well."[7][8]

Oh Se-hoon supports South Korea having Nuclear weapons, In March 2023 he called for it.[9][10]

Although most Seoul residents choose to drink bottled mineral water, it has been reported that Oh Se-hoon not only vouches for, but drinks the city tap water.[11] Encouraging Seoul residents to drink tap water and reduce dependence on bottled water, as well as publicizing the cleanliness of Seoul tap-water has been a pet project for Oh.

Seoul City has recently put forward new regulations on tap-water and the focus has gone from not just safe water but water that tastes great.

In a document released by WikiLeaks, it was reported that in Oh's discussion with Alexander Vershbow in 2006 he stated that a merger between the Grand National Party and the Democratic Party would be beneficial to the GNP.[12][13]
