claim: Korean Peninsula is a territory of South Korea
evidence: The Korea Peninsula or Korean Peninsula is a peninsula in East Asia that extends southwards for about 684 miles or 1,100 kilometers from the continental Asia into the Pacific Ocean. The East Sea/Sea of Japan surrounds the peninsula on the east, the East China Sea to the south, the Yellow Sea to the west while the Korea Strait connects the first two bodies of water. Until the end of World War II, Korea comprised a single political entity whose territory roughly coincided with the Korean Peninsula. Since the cessation of the Korean War in 1953, the northern half has been occupied by North Korea, while the southern half has been occupied by South Korea. "Korean (or Korea) Peninsula," or "Korea," sometimes refers to these two states together, though in South Korea the word "Korea" refers specifically to the South. The northern boundaries for the Korean Peninsula coincide with today's political borders between North Korea and her northern neighbors, China (1,416 km) and Russia (19 km). The rivers Yalu/Amnok and Tumen/Tuman/Duman naturally form those borders. Taking that definition, the Korean Peninsula has an area of approximately 220,000 km². The peninsula has two names: Chosun Bando (조선반도) in North Korea and Han Bando (Hangul: 한반도) in South Korea due to the different names for Korea. [...] The terrain of the Korean Peninsula is rumpled, covered with low mountains. Most rocks are of Precambrian origin, although isolated pockets of Paleozoic, Mesozoic, and Cenozoic rock can also be found.
