South Korea PM Han Seong-sook vows push to resume inter-Korean dialogue
Synopsis
South Korean PM Han Seong-sook is pushing to reopen dialogue with Pyongyang — but the backdrop is anything but diplomatic. A North Korean landmine that injured three South Korean soldiers, a fierce UN confrontation, and an unbridged nuclear standoff all point to the widest inter-Korean gulf in years, making Han's peace overture as much a domestic message as a Pyongyang one.
Key Takeaways
Prime Minister Han Seong-sook pledged on 18 October 2026 to work toward resuming inter-Korean dialogue and peaceful coexistence.

South Korean Prime Minister Han Seong-sook on Sunday, 18 October 2026, pledged that Seoul would press ahead with efforts to reopen dialogue channels with Pyongyang and pursue peaceful coexistence on the divided peninsula. The remarks came even as tensions between the two Koreas remain elevated following a recent landmine incident near their shared border.
What the Prime Minister Said
'Efforts will be made to open the door for dialogue between South Korea and North Korea and to hold talks on peace and joint prosperity,' Han said, addressing a presidential sporting competition in Seoul for displaced North Korean residents. She described inter-Korean division as a 'reality' and acknowledged that the 'pains of displaced residents and separated families are ongoing.' 'Our efforts to open the road to peaceful coexistence of South Korea and North Korea cannot stop,' she added, appealing to participants for their support and thanking them for their contributions to South Korea's economic development and democratisation.
The Landmine Incident That Sharpened Tensions
Han's conciliatory tone comes against the backdrop of a serious security incident. On 8 October, South Korea urged North Korea to take 'responsible measures' at the United Nations, accusing Pyongyang of violating the Armistice Agreement by deliberately planting a landmine that injured three South Korean soldiers near the inter-Korean border in September.
At a committee meeting of the 81st session of the UN General Assembly in New York, South Korean Ambassador to the UN Cha Ji-hoon said a joint investigation by the South Korean military and the United Nations Command (UNC) confirmed that a 21 September explosion was caused by a landmine deliberately planted by North Korean forces south of the Military Demarcation Line (MDL) separating the two Koreas. 'A joint on-site investigation by ROK military and the UNC supported by forensic analysis confirmed that the explosion was caused by a landmine deliberately planted by DPRK forces south of the military demarcation line,' Cha said.
Cha declared the incident a 'clear violation' of the Armistice Agreement and urged the DPRK to 'cease such escalatory actions upon apology and take responsible measures.'
North Korea's Rebuttal
Pyongyang rejected Seoul's account entirely. The North Korean representative at the UN dismissed the accusation as a bid to misrepresent the North's border fortification measures as a military provocation. 'This is no more than a poor trick of the ROK military to shift the blame of its own onto the DPRK,' the representative said. The exchange underscored how deeply entrenched the opposing narratives on inter-Korean security incidents remain.
Nuclear Standoff Echoes Through the Debate
Both sides also reaffirmed their long-held positions on North Korea's nuclear weapons programme. Ambassador Cha reiterated Seoul's commitment to nuclear non-proliferation and called on Pyongyang to return to full compliance with the Nuclear Non-Proliferation Treaty and relevant UN Security Council resolutions. The North Korean representative, in turn, defended Pyongyang's nuclear arsenal as an 'inevitable choice' to protect its sovereignty against what it described as 'decades-long US nuclear threat.' The positions remain irreconcilable in the near term, analysts note.
What to Watch
Prime Minister Han's appeal for dialogue signals that Seoul is keeping diplomatic channels nominally open despite the escalatory signals from the North. Whether Pyongyang responds — or whether the landmine fallout further freezes any prospect of engagement — will be closely watched in the weeks ahead.
Point of View
A public UN rebuke, and an exchange of nuclear red lines. Seoul's pattern of extending peace gestures while simultaneously escalating diplomatic pressure at multilateral forums reflects a dual-track strategy that has rarely moved Pyongyang. The more pointed question is whether the incoming US posture on Korean Peninsula denuclearisation will give Seoul any new leverage — or whether, as in previous cycles, the window for dialogue will open briefly and close without result.
