The China–North Korea border is an international border separating China and North Korea, extending from Korea Bay in the west to a tripoint with Russia in the east. The total length of the border is 1,352 kilometers (840 mi). The current border was created by two secret treaties signed between China and North Korea in 1962 and 1964.
The Sino-Korean Border Agreement (Chinese: 中朝边界条约; Korean: 조중 변계 조약) was signed by China and North Korea on October 12, 1962, in Pyongyang. This agreement and a subsequent agreement in 1964 define the modern border between the two countries. The agreement is widely viewed by both modern scholars and by contemporaries as being favorable to North Korea. As a result of the agreement, North Korea acquired 280 km of territory on and around Paektu Mountain, and 54.5% of the mountain's Heaven Lake. The previous practice of using the Yalu River and Tumen River for the rest of the border was affirmed.
A subsequent agreement followed on March 20, 1964, called the Protocols on the Sino-Korean Border (Chinese: 中朝边界议定书; Korean: 조중 변계 의정서). It was signed in Beijing and determined the sovereignty of 451 islands and islets (264 to North Korea, 187 to China).
The People's Republic of China (PRC) shares land borders with 14 countries (tied with Russia for the most in the world): North Korea, Russia, Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, India, Nepal, Bhutan, Myanmar, Laos, and Vietnam, and with two Special administrative regions of China, Hong Kong and Macao. The land borders, counterclockwise from northeast to southwest, are the China–North Korea border, the eastern segment of the China–Russia border, the China–Mongolia border, the western segment of the China–Russia border, the China–Kazakhstan border, the China–Kyrgyzstan border, the China–Tajikistan border, the China–Afghanistan border, the China–Pakistan border, the western segment of the China–India border (the most contested of the Sino-Indian border dispute), the China–Nepal border, the central segment of the China–India border (Sikkim), the China–Bhutan border, the eastern segment of the China–India border, the China–Myanmar border, the China–Laos border, the China–Vietnam border, a 3-kilometre (1.9 mi) internal border with Macau, a Portuguese territory until 1999, and a 30-kilometre (19 mi) internal border with the special administrative region of Hong Kong, which was a British dependency before 1997.
To the west, China has maritime borders with North Korea, Japan and contested limits with Taiwan and other countries in the South China Sea, among other territorial disputes.
The Yalu River (Chinese: 鸭绿江; pinyin: Yālù Jiāng) or Amnok River (Korean: 압록강; MR: Amnokkang) is a river on the border between China and North Korea. Together with the Tumen River to its east, and a small portion of Paektu Mountain, the Yalu forms the border between China and North Korea. Its valley has been the scene of several military conflicts in the past centuries. It borders North Korea to the south and China to the north.
The Tumen River (Chinese: 图们江; pinyin: Túmén Jiāng, Russian: река Туманная, Korean: 두만강; Korean pronunciation: [tumaŋgaŋ]), also known as the Tuman River or Duman River, is a 521-kilometre (324 mi) long river that serves as part of the boundary between China (left shore), North Korea (right) and Russia (left), rising on the slopes of Mount Paektu and flowing into the Sea of Japan. The river has a drainage basin of 33,800 km (13,100 sq mi).
The river flows in northeast Asia, on the border between China and North Korea in its upper reaches, and between North Korea and Russia in its last 17 kilometers (11 mi) before entering the Sea of Japan. The river forms much of the southern border of Jilin Province in Northeast China and the northern borders of North Korea's North Hamgyong and Ryanggang provinces. Paektu Mountain on the Chinese-North Korean border is the source of the river, as well as of the Yalu River. The two rivers and the region of Paektu Mountain between their headwaters form the border between North Korea and China.
Sinŭiju (Korean: 신의주시; MR: Sinŭiju-si; IPA: [ɕinɰidzu ɕi]) is a city in North Korea which faces Dandong, Liaoning, China, across the international border of the Yalu River. It is the capital of North P'yŏngan province. Part of the city is included in the Sinŭiju Special Administrative Region, which was established in 2002 to experiment with introducing a market economy. In recent years the city has seen increasing tourism from China.
The Sino-Korean Friendship Bridge, or China–North Korea Friendship Bridge, is a bridge across the Yalu or Amnok River on the China–North Korea border. It connects the cities of Dandong in China and Sinuiju of North Korea, by railway and roadway but pedestrians are not allowed to cross between either side. The bridge serves as one of the few ways to enter or leave North Korea.
It was renamed to its current name from the Yalu (Amnok) River Bridge in 1990. The bridge was constructed by the Imperial Japanese Army (IJA) between April 1937 and May 1943 during its occupation of Korea and its puppet state of Manchukuo (now northeast China). Further downstream, construction work on the New Yalu River Bridge began in October 2010.
Paektu Mountain or Baekdu Mountain (Korean: 백두산) is an active stratovolcano on the Chinese–North Korean border. In China, it is known as Changbai Mountain (Chinese: 长白山). At 2,744 m (9,003 ft), it is the tallest mountain in North Korea and Northeast China and the tallest mountain of the Baekdu-daegan and Changbai mountain ranges. The highest peak, called Janggun Peak, belongs to North Korea. The mountain notably has a caldera that contains a large crater lake called Heaven Lake, and is also the source of the Songhua, Tumen, and Yalu rivers. Korean and Manchu people assign a mythical quality to the mountain and its lake, and consider the mountain to be their ancestral homeland.
The mountain's caldera was formed by an eruption in 946 that released about 100–120 km (24–29 cu mi) of tephra. The eruption was among the largest and most powerful eruptions on Earth in the last 5,000 years. The volcano last erupted in 1903, and is expected to erupt around every hundred years. In the 2010s, concerns over an upcoming eruption prompted several countries to commission research into when the volcano might next erupt.The mountain is considered culturally important to multiple groups in the area, including Korean, Chinese, and Manchu people. The mountain is a major national symbol for both North and South Korea, and is mentioned in both national anthems and depicted on the national emblem of North Korea. The Manchu people also consider the mountain their ancestral homeland, and the Chinese Qing dynasty saw it as a symbol of imperial power and the mountain had been subject to territorial disputes over the past few centuries. In the late 20th century, the states of China and North Korea diplomatically agreed to joint custody.
People defect from North Korea for political, material, safety and personal reasons. Defectors flee to various countries, mainly South Korea. In South Korea, they are referred to by several terms, including "northern refugees" and "new settlers".
Towards the end of the North Korean famine of the 1990s, there was a steep increase in defections, reaching a peak in 1998 and 1999. Since then, some of the main reasons for the falling number of defectors have been strict border patrols and inspections, forced deportations, the costs of defection, and the end of the mass famine that swept the country when Soviet aid ceased with the dissolution of the Soviet Union. The most common strategy for defectors is to cross the China–North Korea border into the Chinese provinces of Jilin or Liaoning. About 76% to 84% of defectors interviewed in China or South Korea came from the North Korean provinces bordering China.
The Songhua or Sunghwa River (also Haixi or Xingal, Russian: Сунгари, romanized: Sungari) is one of the primary rivers of China, and the longest tributary of the Amur. It flows about 1,897 km (1,179 mi) from Changbai Mountains on the China–North Korea border through China's northeastern Jilin and Heilongjiang provinces.
The river drains 557,180 km (215,130 sq mi) of land, and has an annual discharge of 76.2 km/a (2,410 m/s) to 81.77 km/a (2,591 m/s).
