The jurisdictional dispute between Gunsan and Gimje regarding the Saemangeum new port is flaring up anew as both municipalities conduct meetings and declarations to solidify their positions. Since the completion of the Saemangeum dyke in 2010, these local governments have been in contention over the jurisdiction of all reclaimed land and infrastructure, with the Saemangeum new port becoming the focal point of this conflict. This is due to the fact that control over the port directly relates to leadership in maritime space and industrial logistics in the region.

The impetus for this renewed discussion is a bill currently pending in the National Assembly, titled 'Act on the Designation of Marine Jurisdiction Areas for Efficient Use and Management of the Sea by Local Governments.' Gunsan city has expressed concerns that this bill could infringe upon local maritime autonomy, vowing to respond collectively with its public sector and citizens. They argue that the bill excludes the 'principle of previous rights' established under existing local autonomy law and could destabilize the foundation of national maritime administration. Specifically, the bill's provision stating that maritime jurisdiction will be determined 'after the jurisdiction of reclaimed land is established' could negatively impact Gunsan city regarding the Saemangeum new port jurisdiction issues.

Gunsan emphasizes that the area around the Saemangeum new port, located between Sinseongdo and Bian-do in communal waters, has historically been under their administrative control for decades, exercising various rights such as fishing permits, maritime security, and quarantine. They plan to conduct training for all officials on the bill and raise public awareness. Meanwhile, Gimje is also preparing a strategy to secure jurisdiction over the reclaimed land surrounding the Saemangeum new port, holding a meeting to review arguments in anticipation of upcoming deliberations by the Central Dispute Mediation Committee within the Ministry of the Interior and Safety. Overall, this dispute highlights the complexities and potential for conflict surrounding local jurisdictions in maritime areas in South Korea.
