The two Koreas will meet on the last day of general-level military talks and will try to narrow their differences on creating a joint-fishing zone in the West Sea.

A government official said it is difficult to find a breakthrough on the matter as the area both sides proposed for the zone are connected to the Northern Limit Line (NLL).

The official added that the South will first agree to parts easier to negotiate with the North and will propose continuing the discussion in the next round of talks if it proves too difficult to come to a conclusion during this round.

During discussions held Thursday, the North proposed creating four joint-fishing areas south of the NLL, while the South said the four zones should be of the same size both north and south of the NLL. The South also proposed one or two trial zones and then expanding operations if creating all four simultaneously is difficult for the North to accept.

The North is said to have rebutted this proposal, saying it is based on an illegitimate demarcation line, the NLL.

The NLL is a military demarcation line in the West Sea between the North and South which was designated by the United Nations Forces in 1953, right after the two Koreas signed an armistice to the Korean War. North Korea has refused to acknowledge the legitimacy of this line since the 1970s on the grounds that it was created without the consensus of Pyongyang.
