북방한계선
The coastline of South Hwanghae is dotted by many small islands, many of which are uninhabited. Many of the largest islands, such as Baengnyeong-do are administered by South Korea. The Northern Limit Line, which runs through the region and demarcates a disputed maritime boundary between the north and south, is another frequent subject of contention between the two countries. The largest islands which indisputably belong to North Korea are Kirin-do, Changrin-do, and Sunwi-do.
