North Korea is located in east Asia on the northern half of the Korean Peninsula. North Korea shares a border with three states, including the China along the Yalu River, Russia along the Tumen River, and South Korea along the Korean Demilitarized Zone. The Yellow Sea and the Korea Bay are off the west coast and the Sea of Japan (also called East Sea of Korea) is off the east coast.

Boundaries, coastline, and islands
The North Korean government claims territorial waters extending 12 nautical miles (22.224 km) from shore. It also claims an exclusive economic zone 200 nautical miles (370.4 km) from shore. In addition, a maritime military boundary that lies fifty nautical miles (92.6 km) offshore in the Sea of Japan (East Sea of Korea) and 200 nautical miles (370.4 km) offshore in the Yellow Sea demarcates the waters and airspace into which foreign ships and planes are prohibited from entering without permission.
Waters of the Yellow Sea are demarcated between North Korea and South Korea by the disputed Northern Limit Line unilaterally drawn by the U.S. military forces in early 1950s and not officially recognized by North Korea.

Maritime claims
The terrain consists mostly of hills and mountains separated by deep, narrow valleys. The coastal plains are wide in the west and discontinuous in the east.

Topography and drainage
Early European visitors to Korea remarked that the country resembled "a sea in a heavy gale" because of the many successive mountain ranges that crisscross the peninsula. Some 80 percent of North Korea's land area is composed of mountains and uplands, with all of the peninsula's mountains with elevations of 2000 m or more located in North Korea. The great majority of the population lives in the plains and lowlands.
Baekdu Mountain (Paektusan), the highest point in North Korea, is a volcanic mountain near the Chinese border with basalt lava plateau with elevations between 1400 and 2000 m above sea level. The Hamgyŏng Range, located in the extreme northeastern part of the peninsula, has many high peaks including Kwanmosan at approximately 1756 m. Other major ranges include the Rangrim Mountains, which are located in the north-central part of North Korea and run in a north-south direction, making communication between the eastern and western parts of the country rather difficult; and the Kangnam Range, which runs along the North Korea-China border. Kŭmgangsan, or Diamond Mountain, (approximately 1,638 meters) in the T'aebaek Range, which extends into South Korea, is famous for its scenic beauty.
For the most part, the plains are small. The most extensive are the P'yŏngyang and Chaeryŏng plains, each covering about 500 square kilometers. Because the mountains on the east coast drop abruptly to the sea, the plains are even smaller there than on the west coast.
The mountain ranges in the northern and eastern parts of North Korea form the watershed for most of its rivers, which run in a westerly direction and empty into the Yellow Sea and Korea Bay. The longest is the Yalu River, which is navigable for 678 of its 790 kilometers. The Tumen River, one of the few major rivers to flow into the Sea of Japan (East Sea of Korea), is the second longest at 521 kilometers but is navigable for only 85 kilometers because of the mountainous topography. The third longest river, the Taedong River, flows through P'yongyang and is navigable for 245 of its 397 kilometers. Lakes tend to be small because of the lack of glacial activity and the stability of the earth's crust in the region. Unlike neighboring Japan or northern China, North Korea experiences few severe earthquakes. The country is well-endowed with spas and hot springs, which number 124 according to one North Korean source.

Environment - current issues: localized air pollution attributable to inadequate industrial controls; water pollution; inadequate supplies of potable water; deforestation.
Environment - international agreements: party to: Antarctic Treaty, Biodiversity, Climate Change, Environmental Modification, Ozone Layer Protection, Ship Pollution (MARPOL 73/78); signed, but not ratified: Antarctic-Environmental Protocol, Law of the Sea.
Lack of information makes it difficult to assess the extent to which industrialization and urbanization have damaged North Korea's natural environment. Using generally obsolete technology transferred from the former Soviet Union and the People's Republic of China, the country embarked on a program of ambitious industrialization after the Korean War.
Air pollution is moderated by the extensive reliance on electricity rather than on fossil fuels, both for industry and the heating of urban residences. Air pollution is further limited by the absence of private automobiles and restrictions on using gasoline-powered vehicles because of the critical shortage of petroleum.
Significant deforestation since the 1990s, due to timber and firewood harvesting, drought, and clearing of farmland. Degradation of farmland due to deforestation has been blamed as a contributing factor in declining crop yields.[1]
