Amid North Korea's continued missile activity and the absence of diplomatic engagement, South Korean President Lee Jae Myung has outlined a phased approach aimed at resolving the long-running dispute over the North's nuclear capabilities. Speaking to a prominent broadcaster, he described a sequence that would begin by freezing the development of North Korea's nuclear and ballistic capabilities, progress toward reducing its weapons stockpile, and eventually lead to full disarmament. Diplomatic and financial incentives would be extended with each step taken toward agreement.
This strategy faces considerable obstacles, given that North Korea views its weapons programme as an essential guarantee of the leadership's continued hold on power and has shown little inclination toward diplomatic engagement on the matter. North Korea has continued conducting weapons tests even as President Donald Trump has sought to restart diplomatic engagement.
Lee is set to present the proposal at this week's United Nations gathering. Addressing reporters prior to his departure for the United States on Monday, ahead of the UN General Assembly in New York, Lee stated that both Seoul and Washington remained open to dialogue with Pyongyang, and outlined a phased denuclearisation framework — halting, reducing, then dismantling — as a practical path toward resolving the nuclear question on the Korean Peninsula. The matter was brought before the General Assembly on Tuesday.
Debate persists over whether denuclearisation of the Korean peninsula can be accomplished through a single agreement — or at all — as Pyongyang continues to expand its weapons capabilities. In remarks delivered last month, Trump put North Korea's nuclear arsenal at 57 warheads, a figure that falls below independent expert assessments placing the total at over 100.
Numerous advocates have long supported a phased approach to denuclearisation, offering economic and political incentives in return. Lee argued that waiting for complete disarmament in a single step was unrealistic given how far the country's nuclear and missile programmes had developed, adding that capabilities would continue to grow in the meantime. He also stated that he had recently called for formal negotiations to end the 1950–53 Korean War as a potential avenue for addressing the nuclear issue.
Some analysts have raised questions about whether Lee's approach might allow North Korea to hold onto its nuclear weapons while securing benefits such as the easing of sanctions. Lee stated that negotiators would need to demonstrate to North Korea that pursuing durable peace represented a viable route to security and prosperity, though whether the country would return to diplomatic talks in the near term remained an open question regardless of the approach adopted.
Referencing what he described as a positive rapport with North Korean leader Kim Jong Un, Trump reduced the scope of a joint military exercise with South Korea the previous month. North Korea's government rejected the move, arguing that partial reductions to the drill did not alter its fundamentally adversarial character. Since then, Pyongyang has carried out three separate ballistic missile launches and issued repeated statements characterising actions by Washington as acts of aggression.
Analysts have assessed that Pyongyang is seeking greater diplomatic concessions from Washington. Lee, who has expressed hope that renewed diplomatic engagement between Washington and Pyongyang would open channels for inter-Korean communication, described the move as a deliberate gesture conveying that the United States harbours no hostile intentions toward North Korea. He added that both Seoul and Washington remain willing to pursue talks with Pyongyang without preconditions, and that what is now required is a policy decision at the level of national leaders. Lee urged the two leaders to meet in person, establish mutual confidence, and find shared positions.
The decision to reduce the scope of the military exercise was disclosed through a social media post, with South Korean officials receiving no advance notification. The statement also referenced what Trump described as Lee's position on not participating in Iran's nuclear disarmament process. Questions about the durability of the alliance between the United States and South Korea subsequently came to the fore.
Lee noted that Trump's move had not been fully anticipated, while also conveying that the president had reaffirmed his intention to foster an environment conducive to negotiations and to ease tensions on the Korean Peninsula. Lee expressed his view that the two nations share closely aligned strategic interests across numerous policy areas, and that he aims to forge a more balanced partnership with Washington for the remainder of Trump's presidency.
According to Lee, a proposed shipbuilding partnership would strengthen naval capacity in the United States while opening fresh avenues for growth among South Korean firms. On Friday, he stated that his armed forces would not be drawn into the conflict in Iran. Plans were under discussion within the administration to broaden the scope of a naval unit stationed in the Gulf of Aden, with the aim of safeguarding the country's commercial vessels and petroleum supply routes.
A bilateral meeting between Lee and Trump was anticipated on the fringes of the UN gathering. The plenary assembly convened. When asked about the North Korean leader's teenage daughter, Lee indicated that his administration had taken note of her growing profile within the country's political hierarchy, while cautioning that it was too early to draw firm conclusions about her role. The country's intelligence service has on multiple occasions identified her as a potential successor to Kim. Certain analysts push back on that assessment, pointing to the patriarchal structure of North Korea's leadership hierarchy.
