If nuclear talks proceed between the United States and North Korea, Pyongyang is also likely to bring back its demand for sanctions relief on a premise that economic activities should be ensured to maintain the political system under Kim.
That day, Trump issued an unprecedented invitation to meet with North Korean leader Kim Jong Un at the Demilitarized Zone between the two Koreas.
On Friday, an influential Tokyo-based pro-DPRK outlet said the USA would need to take "sincere measures" to build trust between the two countries. Animosities have gradually eased since past year when Pyongyang and Washington launched nuclear negotiations, but Seoul has been moving ahead with its already-approved F-35 procurement.
It recently urged Seoul to stop mediating between North Korea and the United States, though Kim joined a brief three-way encounter with Moon and Trump before he and the USA president went into a bilateral meeting at Panmunjom.
Kim is believed to have conveyed the intention to Russian President Vladimir Putin and Chinese President Xi Jinping.
North Korea has also long called for a peace deal with the United States to normalise relations and end the technical state of war that has existed since the 1950-1953 Korean War concluded with an armistice rather than a peace treaty. The administration of President Bill Clinton, in a 1994 agreement with North Korea, stated, "The U.S. will provide formal assurances to the DPRK, against the threat or use of nuclear weapons by the U.S".
She said the US special representative for North Korea, Stephen Biegun, would meet his South Korean counterpart during a visit to Europe this week to discuss ways to achieve this.
The State Department said this week Washington hoped to see a complete freeze in the North Korean nuclear program as the start of a process of denuclearization.
'All UN member states will have to keep vigilance against deliberate attempts by the United States to undermine the peaceful atmosphere that has been created on the Korean peninsula in no easy way, ' the mission said.
A lot of the inner workings of North Korea's leadership have been unclear, and the subject of speculation in the past.
In exchange, leader Kim Jong Un would be expected to dismantle his main nuclear complex at Yongbyon and halt his entire weapons programme, the South Korean news agency reported.
The change is the latest example of Kim's efforts to establish North Korea a normal country that can be trusted with nuclear weapons and operate free from worldwide sanctions.
