The two Koreas are in talks to open their joint liaison office inside North Korea's Gaeseong Industrial Complex later next week.

South Korea's Unification Ministry spokesperson Baik Tae-hyun said at a briefing Friday that discussions are under way to fix the opening date near the end of next week.

According to officials in Seoul, the liaison office is most likely to open next Friday.

The spokesperson added Seoul and Pyongyang have completed consultations on the composition and operation of the liaison office and the only thing left is for the two sides to sign a related deal during the opening ceremony.

Following his North Korea trip Wednesday, Seoul's national security adviser Chung Eui-yong said the two Koreas agreed to open the liaison office before the inter-Korean summit in Pyongyang slated for September 18th to the 20th.
