The Democratic People's Republic of Korea (DPRK) and South Korea ended their first day of the sixth general-level military talks on Tuesday amid disputes on the sea border clashes, the DPRK official news agency reported.

The three-day meeting, which was held in the south side in Panmunjom at Military Demarcation Line (DML), was expected to focus on how to prevent clashes on the West Sea (the Yellow Sea).

During the meeting, the DPRK side blamed South Korea for not showing earnest efforts for the settlement of the West Sea issue, the Korean Central News Agency said.

The DPRK refuses to recognize the current sea border demarcated by the United Nations at the end of the 1950-53 Korean War, and claims the border is too far north.

"It (South Korea) does not hesitate to shamelessly assert that the northern limit line (NLL) is the only marine boundary line in the West Sea of Korea," said the report, quoting Kim Yong Chol, head of the DPRK delegation.

"The south side is categorically rejecting the principled proposals for preventing clashes (on West Sea)," he added.

Kim said redrawing the disputed boundary is the key to preventing skirmishes in the waters near the border area.

The navies of the two sides had two clashes in 1999 and 2002 in the waters of the NLL, resulting in heavy casualties on both sides.

South Korea insists that both sides should respect the current border and has rejected the DPRK's claim to redraw it.

The last inter-Korean military talks of this kind was held in early May at Panmunjom.
