Following all the excitement, back-patting, and media reports of the weekend, The BBC reports that South Korea says it has yet to receive a response from Pyongyang on a summit between North Korean leader Kim Jong-un and US President Donald Trump.
Local media even suggested even more goodwill yesterday with offers of US Embassies in Pyongyang and the release of prisoners.
However, as The BBC reports this morning, details on the planned talks remain vague, with no agreement yet on the location or agenda.
Analysts are skeptical about what can be achieved through talks given the complexity of the issues involved.
"We have not seen nor received an official response from the North Korean regime regarding the North Korea-US summit," a spokesman for the South Korean Ministry of Unification said on Monday.
"I feel they're approaching this matter with caution and they need time to organise their stance."
The surprise proposal for the summit comes after more than a year of heated rhetoric between North Korea and the US, and global concern that the hostilities might escalate into military confrontation. North Korea has conducted several nuclear tests over the past year and developed long-distance missiles it says can carry nuclear bombs as far as the US mainland.
Talks between the countries would mark an unprecedented step in the conflict as no sitting US president has ever met with a North Korean leader.
"Pyongyang probably wants to wait to see how the offer was received in Washington," Andray Abrahamian, Research Fellow at Pacific Forum CSIS, told the BBC.
"There's already been a bit of confusion in the messaging from the White House so it probably makes sense to get some of the ground rules established before go public with it," Mr Abrahamian said.
Speculation continues on where they could meet...
