Di Laut Kuning, dua Korea terbagi oleh sebuah "garis demarkasi militer" maritim de facto dan perbatasan maritim yang disebut Garis Batas Utara (Northern Limit Line, NLL) yang ditetapkan oleh Komando Perserikatan Bangsa-Bangsa pada tahun 1953.[2] NLL tak termuat dalam Perjanjian Gencatan Senjata Korea.[3]
DMZ membentang di dekat paralel ke-38, sepanjang sekitar 248 kilometer.[4] Tentara Amerika dan Korea Selatan berpatroli di garis ini di sepanjang sisi Korea Selatan sementara tentara Korea Utara berpatroli di sepanjang sisi Korea Utara.
Catatan
^The MDL was defined and established in the Korean Armistice Agreement (KAA), Article I, paragraphs 1–11. The KAA includes provisions regarding the MDL and DMZ; but those provisions do not extend into the Yellow Sea or the Sea of Japan. The subsequently devised Northern Boundary Line or NLLDiarsipkan 2012-03-11 di Wayback Machine. was neither initially conceived as part of the MDL, nor have the DPRK and UNC agreed to any subsequent extension of the MDL beyond the agreed upon limits of 1953/7/27.
