South Korea's president has said he would agree to a deal between Donald Trump and Kim Jong Un in which North Korea agreed to freeze production of its nuclear weapons, rather than get rid of them.
Lee Jae Myung told the BBC North Korea was producing an additional 15-20 nuclear weapons a year and that a freeze - as 'an interim emergency measure' - would be 'a feasible, realistic alternative' to denuclearisation for now.
North Korea declared itself a nuclear power in 2022 and vowed to never relinquish its weapons.
'So long as we do not give up on the long-term goal of denuclearisation, I believe there are clear benefits to having North Korea stop its nuclear and missile development,' Lee Jae Myung said.
'The question is whether we persist with fruitless attempts towards the ultimate goal [of denuclearisation] or we set more realistic goals and achieve some of them,' Lee added.
President Lee, who entered office in June, wants to establish peaceful relations with North Korea and reduce tensions, which flared under his predecessor Yoon Suk Yeol, who was impeached for trying to impose martial law last year.
The South Korean leader has been vocal about wanting President Trump to resume nuclear talks with Kim, which broke down in 2019 during Trump's first term, after the US asked the North to dismantle its nuclear facilities.
Lee told the BBC that he thought it possible that Trump and Kim could come back together, given they 'seem to have a degree of mutual trust'. This could benefit South Korea and contribute to global peace and security, he added.
In a speech to parliament on Sunday, the North Korean leader suggested he would be willing to negotiate with Trump – but only if the US dropped its demand for the North to denuclearise.
The BBC sat down with the South Korean president at his office in Seoul, ahead of his trip to the United Nations General Assembly in New York on Monday.
South Korea currently holds the presidency of the UN Security Council, but Lee would not be drawn on whether the body was failing South Korea, because for years both China and Russia have blocked attempts to impose further sanction the North over its nuclear programme.
Earlier this month Chinese President Xi Jinping welcomed Kim at a military parade in Beijing alongside Russia's Vladimir Putin and, unlike in past meetings, China did not publicly mention the North's nuclear weapons or denuclearisation.
Lee said 'While it's clear the UN is falling short when it comes to creating a truly peaceful world, I still believe it is performing many important functions,' adding that reforming the Security Council was 'not very realistic'.
The burgeoning ties between Beijing, Moscow and Pyongyang, on show at China's parade, put South Korea in 'a very difficult situation', Lee said.
South Korea has balanced its relationships between the US - its military ally - and China - which it relies on for much of its trade - but this tightrope is becoming trickier to walk.
This once left-leaning, hardline opposition leader now presents himself as a centrist, carefully choosing his words and positions to navigate South Korea's place in a shifting world.
