The 14th inter-Korean ministerial talks ended Friday without any substantial results.

In a joint statement issued at the end of four-day talks in Pyongyang, the two sides only agreed to hold another round of ministerial talks on August 3rd in Seoul.

Talks bogged down on Wednesday after the two Koreas failed to narrow their differences over several points of contention.

The deadlock came after the North rejected Seoul's demand to follow up on its earlier agreement to hold high-level military talks to ease tensions at the western sea border.

The South Korean delegation reiterated its call on the North to open the military talks within this month to discuss ways on preventing possible naval clashes in the western waters teeming with crab and other fish resources.

North Korea insisted such a meeting would only be possible when South Korea halts its annual joint military drills with the U.S.

The two sides also failed to reach agreements on other pending bilateral issues, including details over the 10th reunion of separated family members.

The five-member South Korean delegation, headed by Unification Minister Jeong Se-hyun, is heading back home later in the day.
