The two Koreas have wrapped up two working-level meetings on preventing floods on rivers that run from the North into the South.

The first of two rounds of talks, which began in the North Korean border city of Gaeseong on Wednesday morning, concluded with the North expressing its regrets and condolences over the death of six South Koreans swept away by a flash flood caused by the North’s discharge of water from one of its dams on the Imjin River last month.

South Korea’s Unification Ministry said the two sides reconvened in the afternoon at 2:30 p.m. for 15 minutes and agreed to continue negotiations on flood prevention at a later date. They will schedule their next meeting through the Panmunjeom channel at the inter-Korean border office.

The ministry added that the South’s senior negotiator to the meetings will announce the results and details of the delegation’s visit upon their return home Wednesday evening.

Initially, the two sides were planning to discuss the joint use of cross-border rivers and prevention of flood in the afternoon session.
