Japan and South Korea ended two days of talks Tuesday still divided over the demarcation of their exclusive economic zones in the Sea of Japan but with an agreement to meet again in September in Seoul, Japanese officials said.

The South Koreans proposed a bigger EEZ for their country, drawing the boundary along the median line between the island of Okinoshima in Shimane Prefecture and the disputed islets under Seoul's control, according to the officials.

Tokyo's position is the boundary should be the median line between the disputed islets -- called Dokdo in South Korea and Takeshima in Japan -- and South Korea's Ullung Island, which lies 87.4 km west of the rocky outcroppings.
