U.S. President Donald Trump announced Friday that his second summit with North Korean leader Kim Jong Un will be held in Hanoi at the end of this month as the two sides seek to inject fresh momentum into denuclearization talks.

The announcement came after the top U.S. envoy to North Korea wrapped up three days of talks with his counterpart in Pyongyang.

"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," Trump wrote on Twitter. "It will take place in Hanoi, Vietnam, on February 27 & 28. I look forward to seeing Chairman Kim & advancing the cause of peace!"
