South Korea's People Power Party to hold open Busan mayoral primary amid rifts

The People Power Party’s nomination management committee, led by Lee Jeong-hyeon, moved to decide Busan’s mayoral nomination through a primary between incumbent Park Hyeong-jun and lawmaker Ju Jin-woo. The party announced the plan in a press release on the 17th, saying the vote would identify Busan’s best leadership for the city’s future.

The reversal comes after a private meeting on the 16th in which Lee publicly floated excluding Park as part of what was described as an “innovative nomination.” The move sparked a confrontation within the committee, with several members walking out of the session.

Park Hyeong-jun blasted the proposal, accusing Lee of destabilizing the process and condemning the leadership’s plan as “a madman’s sword dance.” Ju Jin-woo reportedly urged reconsideration, but Lee pressed ahead, insisting the outcome would be decided by the results of the process.

Pressure from within the party spread to the leadership ranks, including floor leader Song Eon-seok, and Busan-area lawmakers who pressed for a rethink by meeting with party chairman Jang Dong-hyeok. With growing concern among party elites, the decision was ultimately made to proceed with a competitive primary rather than a cut-and-dried nomination.

The move signals a shift from an accelerated or compelled nomination toward an open contest for Busan’s top political post. It also underscores ongoing tensions within the party between reform-minded nomination concepts and traditional internal discipline ahead of local elections.

Busan, Korea’s second-largest city and a major port, represents a key economic and logistical hub in the country. The outcome of its mayoral race could affect local governance, urban development priorities, and the party’s broader strategy ahead of national elections.

For the United States, the development matters because Busan’s leadership touches ports, supply chains, and regional economic policy that influence U.S.-Korea trade and investment. Washington closely watches South Korea’s internal party dynamics, as they can shape alignment on security coordination, defense planning, and economic policy in the Asia-Pacific region.
