WASHINGTON - US President Donald Trump said Friday that he will meet for the second time with Kim Jong-un, top leader of the Democratic People's Republic of Korea (DPRK), on Feb 27-28 in Hanoi, Vietnam.

"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. It will take place in Hanoi, Vietnam, on February 27 & 28," Trump tweeted, referring to the DPRK trip of Stephen Biegun, US special envoy for DPRK-related issues.

"I look forward to seeing Chairman Kim & advancing the cause of peace!" he added.

"North Korea, under the leadership of Kim Jong-un, will become a great Economic Powerhouse," he later tweeted in a separate post.

"He (Kim) may surprise some but he won't surprise me, because I have gotten to know him & fully understand how capable he is. North Korea will become a different kind of Rocket -- an Economic one!" the White House host noted.

Earlier in the day, the State Department said in a statement that during his stay in the DPRK, Biegun had "met with Special Representative for US Affairs of the State Affairs Commission of the DPRK. Kim Hyok Chol February 6-8, in Pyongyang."

The two officials "discussed advancing President Trump and Chairman Kim's Singapore summit commitments of complete denuclearization, transforming US-DPRK relations, and building a lasting peace on the Korean Peninsula," the statement read.

It added that they "agreed to meet again in advance of President Trump and Chairman Kim's second summit."

In his State of the Union address delivered on Feb 5, Trump said that he will meet with Kim Jong-un on Feb 27-28 in Vietnam, but did not disclose the specific location.
