South Korea and the Democratic People's Republic of Korea (DPRK) resumed their vice ministers' talks on Saturday, the second day of such meeting that kicked off on Friday morning.
The third contact between chief delegates was resumed at about 10:40 a.m. local time (0140 GMT) at the DPRK's border city of Kaesong, according to Seoul's unification ministry.
Seoul's three-member delegation was led by Vice Unification Minister Hwang Boo-gi, and his DPRK counterpart was Jon Jong-su, vice director of the secretariat of the Committee for the Peaceful Reunification of Korea.
The two sides continued talks through 10 a.m. on Friday, but failed to narrow differences over major issues.
South Korea has called on the DPRK to agree upon regular reunions of Korean families separated by the 1950-53 Korean War.
Pyongyang has wanted the resumption of tour to the DPRK's scenic resort of Mount Kumgang. The tour, launched in 1998, was suspended in July 2008 when a South Korean female tourist was shot dead by a DPRK solider after venturing into an off-limit area.
