North Korea (Korean: 조선, MR: Chosŏn or literally 북조선, MR: Pukchosŏn), officially the Democratic Peoples Republic of Korea (DPRK or DPR Korea; Korean: 조선민주주의인민공화국, Chosŏn Minjujuŭi Inmin Konghwaguk), is a country in East Asia constituting the northern part of the Korean Peninsula. The country is bordered to the north by China and by Russia along the Amnok (known as the Yalu in Chinese) and Tumen rivers, and to the south by South Korea, with the heavily fortified Korean Demilitarized Zone (DMZ) separating the two. North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands. Pyongyang is the countrys capital and largest city.
