SEOUL, :North Korea's state media said Monday its high-level delegation has made a "meaningful" trip to South Korea that improved stalled inter-Korean relations.

The North's delegation led by its ceremonial head of state Kim Yong-nam returned home late Sunday after a three-day visit to the South for the PyeongChang Winter Olympics. Kim Yo-jong, the younger sister of the North's leader Kim Jong-un, delivered her brother's letter to President Moon Jae-in, which includes an invitation to Pyongyang at an early date.

"The latest trip by the high-level delegation served as an important occasion in improving relations between North and South Korea, and setting up an environment for peace on the Korean Peninsula," reported the Rodong Sinmun, North Korea's main newspaper and the mouthpiece of the ruling party.
