WASHINGTON, Feb. 5 (Yonhap) -- U.S. President Donald Trump announced Tuesday that his second summit with North Korean leader Kim Jong-un will be held in Vietnam Feb. 27-28.
The date and venue had been shrouded in secrecy as the two countries negotiated the next steps after their historic first summit in Singapore in June.
"Much work remains to be done, but my relationship with Kim Jong-un is a good one," Trump said during his State of the Union address.
"Chairman Kim and I will meet again on February 27 and 28 in Vietnam," he said, stopping short of revealing the city.
The announcement came shortly after Washington's nuclear envoy, Stephen Biegun, arrived in Pyongyang to prepare for the next summit.
In meetings with his North Korean counterpart, Kim Hyok-chol, Biegun said earlier that he planned to discuss "corresponding measures" for the elimination of Pyongyang's nuclear and ballistic missile programs.
At the first summit, Trump and Kim committed to establish "new" relations between their countries, build a lasting peace on the Korean Peninsula and work toward complete denuclearization of the peninsula.
Critics have said the agreement lacked detail.
And some, including U.S. Director of National Intelligence Dan Coats, have voiced doubt that the North Koreans will surrender a nuclear program they see as critical to regime survival.
Still, Trump said his diplomatic engagement with North Korea led to concrete results, including the suspension of nuclear and missile tests and the return of American detainees.
"As part of a bold new diplomacy, we continue our historic push for peace on the Korean Peninsula," he said in his speech, adding that had he not been elected president, the U.S. would be in a "major war" with the North.
Vietnam was widely reported to be the host of the second summit, with the central resort city of Da Nang mentioned as a possible location.
The Southeast Asian nation has diplomatic relations with both the U.S. and North Korea and serves as an instructive model for a country that went from being a U.S. adversary to a major partner.
