South and North Korean officials are trying to iron out differences on the third day of inter-Korean ministerial talks in Pyongyang.

The two sides are likely to open a meeting of chief delegates or a group meeting Thursday and focus on narrowing differences that were unveiled during the first full session of the talks earlier on Wednesday.

The South plans to reiterate its call on the North to normalize Mount Geumgang tourism operations and make a firm decision on its nuclear standoff.

Earlier on Wednesday, the South’s chief delegate, Unification Minister Chung Dong-young, stressed that an agreement on denuclearizing the Korean Peninsula must be adopted at the ongoing six-way nuclear talks.

The South also urged the communist state to resume inter-Korean general-grade military talks, stressing the need to bring a permanent peace to the Korean Peninsula.

Seoul also called for the North’s cooperation in determining the fate and whereabouts of South Korean POWs and abductees believed to be in the North and arranging more inter-Korean exchanges in political, military, economic and social fields.

On the recent feud between Hyundai Asan and the North, Chung vowed to exert his best mediatory efforts, citing the subsidies, sacrifice and support the South Korean people and government have poured into the tour project.

Late last month, the North abruptly scaled down the Mount Geumgang tour in an apparent protest of the tour operator's dismissal of its Vice President Kim Yoon-kyu, a Pyongyang favorite.

Meanwhile, the North's delegation called on the South to abolish the National Security Law, calling it an outdated mechanism.

The two sides are scheduled to hold their last session Friday and issue a joint statement.
