South Korean President Moon Jae-in has received North Korean leader Kim Jong-un’s influential sister, Kim Yo-jong, for a landmark meeting at the presidential palace in Seoul.
Mr Moon exchanged pleasantries with Ms Kim and North Korea’s ceremonial head of state Kim Yong-nam on Saturday.
It is the most senior delegation from the north to visit the south since the Korean War in the 1950s.
The meeting comes after the US warned against engagement with Pyongyang.
The Trump administration is cautious of Seoul falling for North Korea’s charm offensive during the Winter Olympics, which are taking place amid tension over Pyongyang’s nuclear programme.
