The United States and North Korea plan to hold a fresh round of talks in a third Asian nation next week as preparations for the second summit between U.S. President Donald Trump and North Korean leader Kim Jong Un ramp up, the South's presidential office said Sunday.

Trump announced Friday that his second summit with Kim will be held in Hanoi on Feb. 27 and 28 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.
