US President Donald Trump and North Korean leader Kim Jong Un will meet for a second much-anticipated summit in Hanoi, as preparations kick into high gear for the peace talks.
Trump announced the exact location on Twitter - only the country, Vietnam, was previously known - for the follow-on to the leaders' summit in Singapore last year as he hailed "very productive" preparatory talks between diplomats from the two countries.
"My representatives have just left North Korea after a very productive meeting and an agreed upon time and date for the second Summit with Kim Jong Un," Mr Trump said.
"It will take place in Hanoi, Vietnam, on February 27 & 28. I look forward to seeing Chairman Kim & advancing the cause of peace!"
The US State Department said the special US envoy for North Korea Stephen Biegun will meet again with Pyongyang officials ahead of the Trump-Kim talks - hours after he returned to Seoul from talks in the North on the summit's agenda.
In a statement, the State Department said talks during Stephen Biegun's three-day trip explored Mr Trump and Kim's "commitments of complete denuclearisation, transforming US-DPRK relations and building a lasting peace on the Korean Peninsula."
The State Department confirmed Mr Biegun agreed to meet his North Korean counterpart Kim Hyok Chol again before the leaders' talks.
North Korea has yet to provide any official confirmation of the summit and Kim Jong Un appeared to make no mention of it during a meeting earlier with the top brass of the Korean People's Army.
As reported by state media, the meeting focused on the need to modernize the military while maintaining party discipline in the ranks.
Mr Biegun is expected to share details of his Pyongyang meetings with his South Korean counterpart Lee Do-hoon and Foreign Minister Kang Kyung-wha on Saturday.
Attention will focus on whether the US team have offered to lift some economic sanctions in return for Pyongyang taking concrete steps toward denuclearisation.
Discussions on declaring an end to the 1950-53 Korean War could also have been on the table, with Mr Biegun last week saying Trump was "ready to end this war."
The three-year conflict ended in an armistice, not a peace treaty, leaving the two Koreas still technically at war, with the US keeping 28,500 troops in the South.
