China stretches some 5,026 kilometres (3,123 mi) across the East Asian landmass bordering the East China Sea, Korea Bay, Yellow Sea, and South China Sea, between North Korea and Vietnam in a changing configuration of broad plains, expansive deserts, and lofty mountain ranges, including vast areas of inhospitable terrain. The eastern half of the country, its seacoast fringed with offshore islands, is a region of fertile lowlands, foothills and mountains, deserts, steppes, and subtropical areas. The western half of China is a region of sunken basins, rolling plateaus, and towering massifs, including a portion of the highest tableland on earth.

In spite of many good harbors along the approximately 18,000-kilometer coastline, the nation has traditionally oriented itself not toward the sea but inland, developing as an imperial power whose center lay in the middle and lower reaches of the Yellow River on the northern plains. China also has the Tibetan Plateau, a very large, high altitude plateau, to the south. To the north of the Tibetan Plateau lie the Gobi and Taklamakan deserts, which stretch from the extreme northwest eastward through Mongolia.

The People's Republic of China is one of the world's largest countries in total area behind Russia and Canada, and very similar to the United States. Figures for the size of China differ slightly depending on where one draws a number of ill-defined boundaries, including claims by the PRC on territories such as Taiwan, Aksai Chin, Trans-Karakoram Tract, and South Tibet.^[1] The official figure by the People's Republic of China is 9.6 million square kilometers. The Republic of China based in Taiwan but claiming to be the government of China puts this figure at 11 million square kilometres,^{[citation needed]} but this includes Mongolia, a state whose sovereignty has been recognized by the PRC. China's contour is reasonably comparable to that of the United States and lies largely at the same latitudes. The total area is estimated to be 9,758,801 km^{2[citation needed]}, with land accounting for 9,326,410 km² and water for 270,550 km² (around 3 percent).

Geography

The Geography of China

From the Tibetan Plateau and other less-elevated highlands rise rugged east-west trending mountains, and plateaus interrupted by deep depressions fanning out to the north and east. The Tibetan Plateau is a vast , elevated plateau covering most of the Tibet Autonomous Region and Qinghai Province in the People's Republic of China and Ladakh in India. With an average elevation of over 4,500 meters, it is the highest and biggest plateau in the world and an area of 2.5 million square kilometers.^[2] A continental scarp marks the eastern margin of this territory, a scarp thaht extends from the Greater Khingan Range in northeastern China, through the Taihang Mountains (a range of mountains overlooking the North China Plain) to the eastern edge of the Yunnan-Guizhou Plateau in the south. All of the low-lying areas of China, which support dense population and intensive cultivation, are to the east of this scarp line.

The east-west ranges include some of Asia's greatest mountains. In addition to the Himalayas and the Kunlun Mountains, there are the Mount Kailash (Gangdise) and the Tian Shan ranges. The latter stands between two great basins, the massive Tarim Basin to the south and the Dzungarian Basin to the north. Rich deposits of coal, oil, and metallic ores lie in the Tian Shan area. The largest inland basin in China, the Tarim Basin measures 1,500 kilometers from east to west and 600 kilometers from north to south at its widest parts. The Himalayas form a natural boundary on the southwest as the Altai Mountains do on the northwest. Lesser ranges branch out, some at sharp angles from the major ranges. The mountains give rise to all the principal rivers. The spine of the Kunlun Mountains separates into several branches as it runs eastward from the Pamir Mountains. The northernmost branches, the Altyn-Tagh and the Qilian Range, form the rim of the Tibetan Plateau in west-central China and overlook the Qaidam Basin, a sandy and swampy region containing many salt lakes. A southern branch of the Kunlun Mountains divides the watersheds of the Yellow River (Huang He) and the Yangtze River (Chang Jiang). The Gansu Corridor, west of the great bend in the Yellow River, was traditionally an important communications link with Central Asia.

North of the 3,300-kilometer-long Great Wall, between Gansu Province on the west and the Greater Khingan Range on the east, lies the Mongolian Plateau, at an average elevation of 1,000 metres above sea level. The Yin Mountains, a system of mountains with average elevations of 1,400 metres, extends east-west through the center of this vast desert steppe. To the south is the largest loess plateau in the world, covering 600,000 square kilometers in Shaanxi Province, parts of Gansu and Shanxi provinces, and some of Ningxia-Hui Autonomous Region. Loess is a yellowish soil blown in from the Inner Mongolian deserts. The loose, loamy material travels easily in the wind, and through the centuries it has veneered the plateau and choked the Yellow River with silt. Because the river level drops precipitously toward the North China Plain where it sluggishly crosses the delta, it carries a heavy load of sediment in the form of sand and mud from the upper reaches, much of which is deposited on the flat plain. The flow is controlled mainly by constantly repaired man-made embankments while floods and course changes have recurred over the centuries. As a result the river flows on a raised ridge fifty meters or more above the plain, Traditionally, rulers were judged by their concern for or indifference to preservation of the embankments.

The Paleozoic formations of China, excepting only the upper part of the Carboniferous system, are marine, while the Mesozoic and Tertiary deposits are estuarine and freshwater, or else of terrestrial origin. Groups of volcanic cones occur in the Great Plain of north China. In the Liaodong and Shandong Peninsulas, there are basaltic plateaus.

Flowing from its source in the Tibetan highlands, the Yellow River courses toward the sea through the North China Plain, the historic center of Chinese expansion and influence. Han Chinese people have farmed the rich alluvial soils of the plain since ancient times, constructing the Grand Canal of China for north-south transport. The plain itself is actually a continuation of the Northeast China Plain to the northeast but is separated from it by the Bohai Gulf, an extension of the Yellow Sea. Like other densely populated areas of China, the plain is subject not only to floods but to earthquakes. For example, the mining and industrial center of Tangshan, about 165 kilometers east of Beijing, was leveled by an earthquake in July 1976 that reportedly also killed 242,000 people and injured 164,000.

The Qinling mountain range, a continuation of the Kunlun Mountains, divides the North China Plain from the Yangtze River Delta and is the major physiographic boundary between the two great parts of China Proper. It is in a sense a cultural boundary as well, influencing the distribution of custom and language. South of the Qinling divide are the densely populated and highly developed areas of the lower and middle plains of the Yangtze and, on its upper reaches, the Sichuan Basin, an area encircled by a high barrier of mountain ranges. The country's longest and most important waterway, the Yangtze River is navigable over much of its length and is now the site of the Three Gorges Dam. Rising on the Tibetan Plateau, the Yangtze River traverses 6,300 kilometers through the heart of the country, draining an area of 1.8 million square kilometers before emptying into the East China Sea. The Sichuan Basin, favored by a mild, humid climate and a long growing season, produces a rich variety of crops; it is also a leading silk-producing area and an important industrial region with substantial mineral resources.

Second only to the Qinling as an internal boundary is the Nanling, the southernmost of the east-west mountain ranges. The Nanling overlooks the part of China where a tropical climate permits two crops of rice to be grown each year. Southeast of the mountains lies a coastal, hilly region of small deltas and narrow valley plains; the drainage area of the Pearl River (Zhu Jiang) and its associated network of rivers occupies much of the region to the south. West of the Nanling, the Yunnan-Guizhou Plateau rises in two steps, averaging 1,200 and 1,800 meters in elevation, respectively, toward the precipitous mountain regions of the eastern Tibetan Plateau.

The Hai River, like the Pearl and other major waterways, flows from west to east. Its upper course consists of five rivers that converge near Tianjin, then flow seventy kilometers before emptying into the Bohai Gulf. Another major river, the Huai, rises in Henan Province and flows through several lakes before joining the Yangtze near Yangzhou. Inland drainage involving a number of upland basins in the north and northeast accounts for about 40 percent of the country's total drainage area. Many rivers and streams flow into lakes or diminish in the desert. Some are useful for irrigation.

China's extensive territorial waters are principally marginal seas of the western Pacific Ocean; these waters wash the shores of a long and much-indented coastline and approximately 5,000 islands. The Yellow, East China, and South China seas, too, are marginal seas of the Pacific Ocean. More than half the coastline (predominantly in the south) is rocky; most of the remainder is sandy. Hangzhou Bay roughly divides the two kinds of shoreline.

Areas of China have experienced earthquakes. On 23 August 1976, a major earthquake in Tangshan killed hundreds of thousands of people. However, most regions of China do not experience earthquakes, as major population centers are a long distance from fault lines. Tangshan is one of the few places in China that is located within an earthquake zone. There are few volcanoes in China.

The topography of China is diverse with snow-capped mountains, deep river valleys, broad basins, high plateaus, rolling plains, terraced hills, sandy dunes, craggy karsts, volcanic calderas, low-latitude glaciers and other landforms present in myriad variations. In general, the land is high in the west and descends to the east coast. Mountains (33%), plateaus (26%) and hills (10%) account for nearly 70% of the country's land surface. Most of the country's arable land and population are based in lowland plains (12%) and basins (19%), though some of the greatest basins are filled with deserts. The country's rugged terrain presents problems for the construction of overland transportation infrastructure and requires extensive terracing to sustain agriculture, but are conducive to the development of forestry, mineral and hydropower resources and tourism.

The world's tallest mountains, the Himalayas, Karakorum, Pamirs and Tian Shan divide China from South and Central Asia. Eleven of the 17 tallest mountain peaks are located on China's western borders. They include world's tallest peak Mt. Everest (8848m) in the Himalyas on the border with Nepal and the world's second tallest peak, K2 (8611m) on the border with Pakistan. From these towering heights in the west, the land descends in steps like a terrace.

North of the Himalayas and east of the Karakorum/Pamirs is the vast Tibetan Plateau, the largest and highest plateau in the world, also known as the "Roof of the World." The plateau has an average elevation of 4,000m above sea level and covers an area of 2.5 million square kilometers, or about one-fifth of China's land mass. In the north, the plateau is hemmed in by the Kunlun Mountains, which extends eastward from the intersection of the Pamirs, Karakorum and Tian Shan.

Northwest of the Tibetan Plateau, between the northern slope of Kunlun and southern slope of Tian Shan, is the vast Tarim Basin of Xinjiang, which contains the Taklamakan Desert. The Tarim Basin, the largest in China, measures 1,500 km from east to west and 600 km from north to south at its widest parts. Average elevation in the basin is 1,000m. To east, the basin descends into the Hami-Turpan Depression of eastern Xinjiang, where the dried lake bed of Lake Ayding at -154m below sea level, is the lowest surface point in China and the third lowest in the world. With temperatures that have reached 49.6 C, the lake bed ranks as one the hottest places in China. North of Tian Shan is Xinjiang's second great basin, the Jungar, which contains the Gurbantünggüt Desert. The Jungar Basin is enclosed to the north by the Altay Mountains which separates Xinjiang from Russia and Mongolia.

Northeast of the Tibetan Plateau, the Altun Shan-Qilian Mountains range branches off the Kunlun and creates a parallel mountain range running east-west. In between in northern Qinghai is the Qaidam Basin, with elevation of 2,600-3,000m and numerous brackish and salt lakes. North of the Qilian is Hexi Corridor of Gansu, a natural passage between Xinjiang and China Proper that was part of the ancient Silk Road and traversed by modern highway and rail lines to Xinjiang. Further north, the Inner Mongolian Plateau, between 900-1,500m in elevation, arcs north up the spine of China and becomes the Greater Hinggan Range of Northeast China.

East of the Tibetan Plateau, deeply folded mountains fan out toward the Sichuan Basin, which is ringed by mountains in 1,000-3,000m elevation. The floor of the basin has an average elevation of 500m and is home to one of the most densely farmed and populated regions of China. The Sichuan Basin is capped in the north by the eastward continuation of the Kunlun range, the Qinling and Dabashan. The Qinling and Dabashan ranges form a major north-south divide across China Proper, the traditional core area of China. Southeast of the Tibetan Plateau and south of the Sichuan Basin is the Yunnan-Guizhou Plateau, which occupy much of southwest China. This plateau, with an average elevation of 2,000m, is known for limestone karst landscape.

Between the Qinling and the Inner Mongolian Plateau is Loess Plateau, the largest of its kind in the world, covering 650,000 km² in Shaanxi, parts of Gansu and Shanxi provinces, and some of Ningxia-Hui Autonomous Region. The plateau is 1,000-1,500m in elevation and is filled with loess, a yellowish, loose soil that travels easily in the wind. Eroded loess silt give the Yellow River its color and name. The Loess Plateau is bound to the east by the Luliang Mountain of Shanxi, which has a narrow basin running north to south along the Fen River. Further east is the Taihang Mountains of Hebei, the dominant topographical feature of North China.

The Taihang forms the western side of the triangular North China Plain. The other two sides are the Pacific Coast to the east and the Yangtze River to the southwest. The vertices of this triangle are Beijing to the north, Shanghai to the southeast and Yichang to the southwest. This alluvial plain, fed by the Yellow and Yangtze Rivers, is one of the most heavily populated regions of China. The only mountains in the plain are the Taishan in Shandong and Dabie Mountains of Anhui.

South of the Yangtze, the landscape is more rugged. Like Shanxi Province to the north, each of Hunan and Jiangxi has a provincial core in a river basin that is surrounded by mountains. The Wuling range separates Guizhou from Hunan. The Luoxiao and Jinggang divides Hunan from Jiangxi, which is separated from Fujian by the Wuyi Mountains. The southeast coastal provinces, Zhejiang, Fujian and Guangdong have rugged coasts, with pockets of lowland and mountainous interior. The Nanling, a east-west mountain range, across northern Guangdong, seals off Hunan and Jiangxi from Guangdong.

Beijing, situated at the north tip of the North China Plain, is shielded by the intersection of Taihang and Jingdu Mountains. Further north are the drier grasslands of the Inner Mongolian Plateau, traditionally home to pastoralists. To the south are agricultural regions, traditionally home to sedentary populations. The Great Wall of China was built in the mountains across the mountains that mark the southern edge of the Inner Mongolian Plateau. The Ming-era walls run 2,000 km east-to-west from Shanhaiguan on the Bohai Coast to the Hexi Corridor in Gansu. Northeast of Shanhaiguan, a narrow sliver of flat coastal land opens up into the vast Manchurian Plain. The plains extend north to the crown of the "Chinese rooster," near where the Greater and Lesser Hinggan ranges converge. The Changbai Mountains to the east divide China from the Korean peninsula.

Tallest mountain peaks in China

The tallest peak entirely within China is Shishapangma (8013m, 14th) of the Tibetan Himalayas in Nyalam County of Tibet Autonomous Region.

Besides Mt. Everest and K2, the other 9 of the world's 17 tallest peaks on China's western borders are: Lhotse (8516m, 4th highest), Makalu (8485m, 5th), Cho Oyu (8188m, 6th), Gyachung Kang (7952m, 15th) of the Himalayas on the border with Nepal and Gasherbrum I (8080m, 11th), Broad Peak (8051m, 12th), Gasherbrum II (8035m, 13th), Gasherbrum III (7946m, 16th) and Gasherbrum IV (7932m, 17th) of the Karakorum on the border with Pakistan. The tallest peak entirely within China is Shishapangma (8013m, 14th) of the Tibetan Himalayas in Nyalam County of Tibet Autonomous Region. In all, 9 of the 14 mountain peaks in the world over 8,000m are in or on the border of China. Another notable Himalyan peak in China is Namchabarwa (7782m, 28th), near the great bend of the Yarlungtsanpo River in eastern Tibet, and considered to be the eastern anchor of the Himalayas.

Outside the Himalayas and Karakorum, China's tallest peaks are Kongur Tagh (7649m, 37th) and Muztagh Ata (7546m, 43rd) in the Pamirs of western Xinjiang, Gongga Shan (7556m, 41st) in the Great Snowy Mountains of western Sichuan; and Tömür Shan (7,439m, 60th), the highest peak of Tian Shan, on the border with Kyrgyzstan.

Climate

The climate of China is extremely diverse; Dry in the south to subarctic in the north. Monsoon winds, caused by differences in the heat-absorbing capacity of the continent and the ocean, dominate the climate. Alternating seasonal air-mass movements and accompanying winds are moist in summer and dry in winter. The advance and retreat of the monsoons account in large degree for the timing of the rainy season and the amount of rainfall throughout the country. Tremendous differences in latitude, longitude, and altitude give rise to sharp variations in precipitation and temperature within China. Although most of the country lies in the temperate belt, its climatic patterns are complex.

Parts of China's northernmost province Heilongjiang has a subarctic climate; its southernmost part, Hainan Island (an island away from mainland China), has a tropical climate. Temperature differences in winter are great, but in summer the diversity is considerably less. For example, the north of Heilongjiang has an average January mean temperature of below −20 °C (−4 °F), and the reading may drop to −40 °C (−40 °F); the average July mean in the same area may exceed 20 °C (68 °F). By contrast, the central and southern parts of Guangdong province experience an average January temperature of above 10 °C (50 °F), while the July mean is generally above 28 °C (82 °F).

Precipitation varies regionally even more than temperature. The part of China south of the Qin Mountains experiences abundant rainfall, often above 1,000 millimetres (39 in), most of it coming with the monsoon during summer and late spring. To the north and west of the range, however, rainfall is uncertain. The farther north and west one moves, the scantier and more uncertain it becomes. The northwest has the lowest annual rainfall in the country and hardly any precipitation in its desert areas. China experiences frequent typhoons (about five per year along southern and eastern coasts), damaging floods, monsoons, tsunamis, dust storms, and droughts.

Principal rivers and drainage

See also: List of rivers of China

China has 50,000 rivers totaling some 420,000 kilometers in length and each having a catchment area of more than 100 square kilometers. Some 1,500 of these rivers each have catchment areas exceeding 1,000 square kilometers. Most rivers flow from west to east and empty into the Pacific Ocean. The Yangzi (Changjiang or Yangtze River), which rises in Tibet, flows through Central China, and, having traveled 6,300 kilometers, enters the Yellow Sea near Shanghai. The Yangzi has a catchment area of 1.8 million square kilometers and is the third longest river in the world after the Amazon and the Nile. The second longest river in China is the Huanghe (Yellow River), which also rises in Tibet and travels circuitously for 5,464 kilometers through North China before reaching the Bo Hai Gulf on the north coast of Shandong Province. It has a catchment area of 752,000 square kilometers. The Heilongjiang (Heilong or Black Dragon River) flows for 3,101 kilometers in Northeast China and an additional 1,249 in Russia, where it is known as the Amur. The longest river in South China is the Zhujiang (Pearl River), which is 2,214 kilometers long. Along with its three tributaries, the Xi, Dong, and Bei—West, East, and North—rivers, it forms the rich Pearl River Delta near Guangzhou, Zhuhai, Macau, and Hong Kong. Other major rivers are the Liaohe in the northeast, Haihe in the north, Qiantang in the east, and Lancang in the southwest.

Because the river level drops precipitously toward the North China Plain, where it continues a sluggish course across the delta, it transports a heavy load of sand and mud from the upper reaches, much of which is deposited on the flat plain. The flow is channeled mainly by constantly repaired manmade embankments; as a result the river flows on a raised ridge fifty meters or more above the plain, and waterlogging, floods, and course changes have recurred over the centuries. Traditionally, rulers were judged by their concern for or indifference to preservation of the embankments. In the modern era, China has undertaken extensive flood control and conservation measures.

Flowing from its source in the Qingzang highlands, the Yellow River courses toward the sea through the North China Plain, the historic center of Chinese expansion and influence. Han Chinese people have farmed the rich alluvial soils of the plain since ancient times, constructing the Grand Canal for north-south transport (see History of China - Imperial era). The plain itself is actually a continuation of the Dongbei (Manchurian) Plain to the northeast but is separated from it by the Bohai Gulf, an extension of the Yellow Sea.

Like other densely populated areas of China, the plain is subject not only to floods but to earthquakes. For example, the mining and industrial center of Tangshan, about 165 km east of Beijing, was leveled by an earthquake in July 1976 that was believed to be the largest earthquake of the 20th century by death toll.

The Qin Mountains, a continuation of the Kunlun Mountains, divides the North China Plain from the Yangtze River Delta and is the major physiographic boundary between the two great parts of China Proper. It is in a sense a cultural boundary as well, influencing the distribution of custom and language. South of the Qinling mountain range divide are the densely populated and highly developed areas of the lower and middle plains of the Yangtze River and, on its upper reaches, the Sichuan Basin, an area encircled by a high barrier of mountain ranges.

The country's longest and most important waterway, the Yangtze River is navigable over much of its length and has a vast hydroelectric potential. Rising on the Qingzang Plateau, the Yangtze River traverses 6,300 km through the heart of the country, draining an area of 1.8 million km² before emptying into the East China Sea. The roughly 300 million people who live along its middle and lower reaches cultivate a great rice- and wheat-producing area. The Sichuan Basin, favored by a mild, humid climate and a long growing season, produces a rich variety of crops; it is also a leading silk-producing area and an important industrial region with substantial mineral resources.

Second only to the Qinling range as an internal boundary is the Nanling, the southernmost of the east-west mountain ranges. The Nanling overlooks the part of China where a tropical climate permits two crops of rice to be grown each year. Southeast of the mountains lies a coastal, hilly region of small deltas and narrow valley plains; the drainage area of the Pearl River and its associated network of rivers occupies much of the region to the south. West of the Nanling, the Yunnan-Guizhou Plateau rises in two steps, averaging 1,200 and 1,800 m in elevation, respectively, toward the precipitous mountain regions of the eastern Qingzang Plateau.

The Hai River, like the Pearl River and other major waterways, flows from west to east. Its upper course consists of five rivers that converge near Tianjin, then flow seventy kilometers before emptying into the Bohai Gulf. Another major river, the Huai River, rises in Henan Province and flows through several lakes before joining the Pearl River near Yangzhou.

Inland drainage involving a number of upland basins in the north and northeast accounts for about 40 percent of the country's total drainage area. Many rivers and streams flow into lakes or diminish in the desert. Some are useful for irrigation.

China's extensive territorial waters are principally marginal seas of the western Pacific Ocean; these waters wash the shores of a long and much-indented coastline and approximately 5,000 islands. The Yellow Sea, East China Sea, and South China Sea, too, are marginal seas of the Pacific Ocean. More than half the coastline (predominantly in the south) is rocky; most of the remainder is sandy. The Bay of Hangzhou roughly divides the two kinds of shoreline.

Environment

Main article: Environment of China

Air pollution (sulfur dioxide particulates) from reliance on coal is a major issue, along with water pollution from untreated wastes and use of debated standards of pollutant concentration rather than Total Maximum Daily Load. There are water shortages, particularly in the north. The eastern part of China often experiences smoke and dense fog in the atmosphere as a result of industrial pollution. Heavy deforestation with an estimated loss of one-fifth of agricultural land since 1949 to soil erosion and economic development is occurring with resulting desertification. The size of the Gobi desert has increased and now reaches the outskirts of Beijing.^{[citation needed]}

China is a party to the Antarctic-Environmental Protocol, the Antarctic Treaty, the Convention on Biological Diversity, the Climate Change treaty, the United Nations Convention to Combat Desertification, the Endangered Species treaty, the Hazardous Wastes treaty, the Law of the Sea, the International Tropical Timber Agreements of 1983 and 1994, the International Convention for the Regulation of Whaling, and agreements on Marine Dumping, Ozone Layer Protection, Ship Pollution, and Wetlands protection. China has signed, but not ratified the Kyoto Protocol (but is not yet required to reduce its carbon emission under the agreement, as is India), and the Nuclear Test Ban treaty.

Natural resources

China has substantial mineral reserves and is the world’s largest producer of antimony, natural graphite, tungsten, and zinc. Other major minerals are aluminum, bauxite, coal, crude petroleum, diamonds, gold, iron ore, lead, magnetite, manganese, mercury, molybdenum, natural gas, phosphate rock, tin, uranium, and vanadium. With its vast mountain ranges, China’s hydropower potential is the largest in the world.

Land use

Based on 2005 estimates, 14.86% (about 1.4 million km²) of China’s total land area is arable. About 1.3% (some 116,580 km²) is planted to permanent crops and the rest planted to temporary crops. With comparatively little land planted to permanent crops, intensive agricultural techniques are used to reap harvests that are sufficient to feed the world’s largest population and still have surplus for export. An estimated 544,784 km² of land were irrigated in 2004. 42.9% of total land area was used as pasture, and 17.5% was forest.

Habitats

In History

The Central plain, visible in dark orange.

Chinese history is often explained in terms of several strategic areas, definite by particular topographic limits. Starting from the Chinese central plain, the former heart of the Han populations, the Han people expanded militarily and then demographically toward the Loess plateau, the Sichuan plain, and the Southern hills, not without resistance from local populations. Pushed by its comparatively higher demographic growth, the Han continued their expansion by military and demographic waves. The far-south of nowadays China, the northern parts of today's Vietnam, the Tarim basin were first reached and durably subdued by the Han dynasty's armies. The Northern steppes were always the source of invasions into China, which culminated in the XIIIth century by Mongolian conquest of the whole China and creation of Mongolian Yuan dynasty. The Manchurian plain and Korean peninsula were usually not under Chinese control, with the exception of some limited periods of occupation. The Manchurian plain became strongly integrated into the Chinese empire during the late Qing dynasty, while the West side of the Changbai mountains, formerly the home of Korean tribes, thus also entered China.

Later 19th and 20th centuries struggles led the Chinese Empire to collapse under westerners pressures, and the PRC to rise under its today shape.

Wildlife

Main article: Wildlife of China

China lies in two of the world's major ecozones, the Palearctic and the Indomalaya. In the Palearctic zone are found such important mammals as the horse, camel, tapir, and jerboa. Among the species found in the Indomalaya region are the Leopard Cat, bamboo rat, treeshrew, and various other species of monkeys and apes. Some overlap exists between the two regions because of natural dispersal and migration, and deer or antelope, bears, wolves, pigs, and rodents are found in all of the diverse climatic and geological environments. The famous giant panda is found only in a limited area along the Chang Jiang. There is a continuing problem with trade in endangered species, although there are now laws to prohibit such activities.

Boundary disputes

Map of the People's Republic of China (click to enlarge), Source: CIA

China's borders have more than 20,000 km of land frontier shared with nearly all the nations of mainland East Asia, were disputed at a number of points. In the western sector, China claimed portions of the 41,000 km² Pamir Mountains area, a region of soaring mountain peaks and glacial valleys where the borders of Afghanistan, Pakistan, the Soviet Union, and China meet in Central Asia. North and east of this region, some sections of the border remained undemarcated in 1987. The 6,542 km frontier with the Soviet Union has been a source of continual friction. In 1954 China published maps showing substantial portions of Soviet Siberian territory as its own. In the northeast, border friction with the Soviet Union produced a tense situation in remote regions of Inner Mongolia and Heilongjiang along segments of the Argun River, Amur River, and Ussuri River. Each side had massed troops and had exchanged charges of border provocation in this area. In a September 1986 speech in Vladivostok, Soviet leader Mikhail S. Gorbachev offered the Chinese a more conciliatory position on Sino-Soviet border rivers. In 1987 the two sides resumed border talks that had been broken off after the 1979 Soviet invasion of Afghanistan (see Sino-Soviet relations). Although the border issue remained unresolved as of late 1987, China and the Soviet Union agreed to consider the northeastern sector first. In October 2004, China signed an agreement with Russia on the delimitation of their entire 4,300-kilometer-long border, which had long been in dispute.

A major dispute between China and India focuses on the northern edge of their shared border, where the Aksai Chin area of northeastern Jammu and Kashmir is under Chinese de facto administration but claimed by India and Pakistan. Eastward from Bhutan and north of the Brahmaputra River (Yarlung Zangbo Jiang) lies a large area controlled and administered by India but claimed by the Chinese. The area was demarcated by the British McMahon Line, drawn along the Himalayas in 1914 as the Sino-Indian border; India accepts and China rejects this boundary. In June 1980 China made its first move in twenty years to settle the border disputes with India, proposing that India cede the Aksai Chin area in Jammu and Kashmir to China in return for China's recognition of the McMahon Line; India did not accept the offer, however, preferring a sector-by-sector approach to the problem. In July 1986 China and India held their seventh round of border talks, but they made little headway toward resolving the dispute. Each side, but primarily India, continued to make allegations of incursions into its territory by the other. Most of the mountainous and militarized boundary with India is still in dispute, but Beijing and New Delhi have committed to begin resolution with discussions on the least disputed middle sector. India does not recognize Pakistan’s ceding lands to China in a 1964 boundary agreement.

The China-Burma border issue was settled October 1, 1960, by the signing of the Sino-Burmese Boundary Treaty. The first joint inspection of the border was completed successfully in June 1986.

China is involved in a complex dispute with Malaysia, Philippines, Vietnam, and possibly Brunei over the Spratly (Nansha) Islands in the South China Sea. The 2002 "Declaration on the Conduct of Parties in the South China Sea" eased tensions but fell short of a legally binding code of conduct desired by several of the disputants. China also occupies the Paracel (Xisha) Islands, which are also claimed by Vietnam, and asserts a claim to the Japanese-administered Senkaku Islands (Diaoyu Tai) in the Pacific Ocean.

Antipodes

Most of coastal and western central China, including Beijing, are antipodal to Argentina and Chile. Taiwan is antipodal to Paraguay. Wuhai, for example, is antipodal to Valdivia, Chile. See Geography of Chile#Antipodes, Geography of Argentina#Antipodes, and Geography of Paraguay#Antipodes for details.
