The two Koreas have agreed in principle to talks aimed at mending their almost nonexistent relations, but they are stalled on the question of where to meet.
South Korea has suggested that high-level talks take place in its capital, Seoul, but North Korea has countered that only lower-level negotiations should take place and they should be held in its border city of Kaesong.
The rival Koreas have not met face to face for such negotiations since February 2011.
