Imperial China-
The Warring States period ended in 221 BCE, after the state of Qin conquered the other six kingdoms and established the first unified Chinese state. Qin Shi Huang, the emperor of Qin, proclaimed himself the "First Emperor" and imposed reforms throughout China, notably the forced standardization of the Chinese language, measurements, length of cart axles, and currency. The Qin Dynasty lasted only fifteen years, falling soon after Qin Shi Huang's death, as its harsh legalist and authoritarian policies led to widespread rebellion.
The subsequent Han Dynasty ruled China between 206 BCE and 220 CE, and created a lasting Han cultural identity among its populace that has endured to the present day. The Han Dynasty expanded the empire's territory considerably with military campaigns reaching Korea, Vietnam, Mongolia and Central Asia, and also helped establish the Silk Road in Central Asia. Han China gradually became the largest economy of the ancient world. The Han Dynasty adopted Confucianism, a philosophy developed in the Spring and Autumn period, as its official state ideology. Despite the Han's official abandonment of Legalism, the official ideology of the Qin, Legalist institutions and policies remained and formed the basis of the Han government.
After the collapse of Han, a period of disunion known as the period of the Three Kingdoms followed. In 581 CE, China was reunited under the Sui. However, the Sui Dynasty declined following its defeat in the Goguryeo–Sui War (598–614).
Under the succeeding Tang and Song dynasties, Chinese technology and culture entered a golden age. The An Shi Rebellion in the 8th century devastated the country and weakened the dynasty.
The Song Dynasty was the first government in world history to issue paper money and the first Chinese polity to establish a permanent standing navy. Between the 10th and 11th centuries, the population of China doubled in size to around 100 million people, mostly due to the expansion of rice cultivation in central and southern China, and the production of abundant food surpluses. The Song Dynasty also saw a flourishing of philosophy and the arts, as landscape art and portrait painting were brought to new levels of maturity and complexity, and social elites gathered to view art, share their own and trade precious artworks. The Song Dynasty saw a revival of Confucianism, in response to the growth of Buddhism during the Tang. In the 13th century, China was gradually conquered by the Mongol empire. In 1271, the Mongol leader Kublai Khan established the Yuan Dynasty; the Yuan conquered the last remnant of the Song Dynasty in 1279. Before the Mongol invasion, the population of Song China was 120 million citizens; this was reduced to 60 million by the time of the census in 1300. A peasant named Zhu Yuanzhang overthrew the Yuan Dynasty in 1368 and founded the Ming Dynasty. Under the Ming Dynasty, China enjoyed another golden age, developing one of the strongest navies in the world and a rich and prosperous economy amid a flourishing of art and culture. It was during this period that Zheng He led explorations throughout the world, reaching as far as Africa. In the early years of the Ming Dynasty, China's capital was moved from Nanjing to Beijing. During the Ming Dynasty, philosophers such as Wang Yangming further critiqued and expanded Neo-Confucianism with concepts of individualism and innate morality.
In 1644, Beijing was captured by a coalition of rebel forces led by Li Zicheng, a minor Ming official who led the peasant revolt. The last Ming Chongzhen Emperor committed suicide when the city fell. The Manchu Qing Dynasty then allied with Ming Dynasty general Wu Sangui and overthrew Li's short-lived Shun Dynasty, and subsequently seized control of Beijing, which became the new capital of the Qing Dynasty.
End of Dynastic Rule-
The Qing Dynasty, which lasted from 1644 until 1912, was the last imperial dynasty of China. In the 19th century, the Qing Dynasty experienced Western imperialism following the First Opium War (1839–42) and the Second Opium War (1856–60) with Britain. China was forced to sign unequal treaties, pay compensation, allow extraterritoriality for foreign nationals, and cede Hong Kong to the British under the 1842 Treaty of Nanking. The First Sino-Japanese War (1894−95) resulted in Qing China's loss of influence in the Korean Peninsula, as well as the cession of Taiwan to Japan.
The Qing dynasty also began experiencing internal unrest in which millions of people died. In the 1850s and 1860s, the failed Taiping Rebellion ravaged southern China. Other major rebellions included the Punti–Hakka Clan Wars (1855–67), the Nien Rebellion (1851–68), the Miao Rebellion (1854–73), the Panthay Rebellion (1856–73) and the Dungan revolt(1862–77).
In the 19th century, the great Chinese Diaspora began. Losses due to emigration were added to by conflicts and catastrophes such as the Northern Chinese Famine of 1876–1879, in which between 9 and 13 million people died. In 1898, the Guangxu Emperor drafted a reform plan to establish a modern constitutional monarchy, but he was overthrown by the Empress Dowager Cixi in a coup d'état. The ill-fated anti-Western Boxer Rebellion of 1899–1901 further weakened the Qing Dynasty. The Xinhai Revolution of 1911–12 brought an end to the Qing Dynasty and established the Republic of China.
People's Republic of China (1949–present)
Major combat in the Chinese Civil War ended in 1949 with the Communist Party in control of most of mainland China, and the Kuomintang retreating offshore, reducing the ROC's territory to only Taiwan, Hainan, and their surrounding islands. On 1 October 1949, Communist Party Chairman Mao Zedong proclaimed the establishment of the People's Republic of China. In 1950, the People's Liberation Army succeeded in capturing Hainan from the ROC and occupying Tibet. However, remaining Nationalist forces continued to wage an insurgency in western China throughout the 1950s.
Mao encouraged population growth, and under his leadership the Chinese population almost doubled from around 550 million to over 900 million. However, Mao's Great Leap Forward, a large-scale economic and social reform project, resulted in an estimated 45 million deaths between 1958 and 1961, mostly from starvation. Between 1 and 2 million landlords were executed as "counterrevolutionaries." In 1966, Mao and his allies launched the Cultural Revolution, sparking a period of political recrimination and social upheaval which lasted until Mao's death in 1976. In October 1971, the PRC replaced the Republic of China in the United Nations, and took its seat as a permanent member of the Security Council.
Biodiversity-
China is one of 17 megadiverse countries, lying in two of the world's majo recozones: the Palearctic and the Indomalaya. By one measure, China has over 34,687 species of animals and vascular plants, making it the third-most biodiverse country in the world, after Brazil and Colombia. The country signed the Rio de Janeiro Convention on Biological Diversity on 11 June 1992, and became a party to the convention on 5 January 1993. It later produced a National Biodiversity Strategy and Action Plan, with one revision that was received by the convention on 21 September 2010.
China is home to at least 551 species of mammals (the third-highest such number in the world), 1,221 species of birds (eighth), 424 species of reptiles (seventh) and 333 species of amphibians (seventh). China is the most biodiverse country in each category outside of the tropics. Wildlife in China share habitat with and bear acute pressure from the world's largest population of homo sapiens. At least 840 animal species are threatened, vulnerable or in danger of local extinction in China, due mainly to human activity such as habitat destruction, pollution and poaching for food, fur and ingredients for traditional Chinese medicine. Endangered wildlife is protected by law, and as of 2005, the country has over 2,349 nature reserves, covering a total area of 149.95 million hectares, 15 percent of China's total land area.
China has over 32,000 species of vascular plants, and is home to a variety of forest types. Cold coniferous forests predominate in the north of the country, supporting animal species such as moose and Asian black bear, along with over 120 bird species. The understorey of moist conifer forests may contain thickets of bamboo. In higher montane stands of juniper and yew, the bamboo is replaced by rhododendrons. Subtropical forests, which are predominate in central and southern China, support as many as 146,000 species of flora. Tropical and seasonal rainforests, though confined to Yunnan and Hainan Island, contain a quarter of all the animal and plant species found in China. China has over 10,000 recorded species of fungi, and of them, nearly 6,000 are higher fungi.
Environmental issues-
In recent decades, China has suffered from severe environmental deterioration and pollution. While regulations such as the 1979 Environmental Protection Law are fairly stringent, they are poorly enforced, as they are frequently disregarded by local communities and government officials in favor of rapid economic development. Urban air pollution is a severe health issue in the country; the World Bank estimated in 2013 that 16 of the world's 20 most-polluted cities are located in China. China is the world's largest carbon dioxide emitter. The country also has water problems. Roughly 298 million Chinese in rural areas do not have access to safe drinking water, and 40% of China's rivers had been polluted by industrial and agricultural waste by late 2011. This crisis is compounded by increasingly severe water shortages, particularly in the north-east of the country.
However, China is the world's leading investor in renewable energy commercialization, with $52 billion invested in 2011 alone; it is a major manufacturer of renewable energy technologies and invests heavily in local-scale renewable energy projects. By 2009, over 17% of China's energy was derived from renewable sources – most notably hydroelectric power plants, of which China has a total installed capacity of 197 GW. In 2011, the Chinese government announced plans to invest four trillion yuan (US$618.55 billion) in water infrastructure and desalination projects over a ten-year period, and to complete construction of a flood prevention and anti-drought system by 2020. In 2013, China began a five-year, US$277-billion effort to reduce air pollution, particularly in the north of the country.
Foreign Relation-
The PRC has diplomatic relations with 171 countries and maintains embassies in 162. Its legitimacy is disputed by the Republic of China and a few other countries; it is thus the largest and most populous state with limited recognition. In 1971, the PRC replaced the Republic of China as the sole representative of China in the United Nations and as one of the five permanent members of the United Nations Security Council. China was also a former member and leader of the Non-Aligned Movement, and still considers itself an advocate for developing countries. Along with Brazil, Russia, India and South Africa, China is a member of the BRICS group of emerging major economies and hosted the group's third official summit at Sanya, Hainan in April 2011.
Under its interpretation of the One-China policy, Beijing has made it a precondition to establishing diplomatic relations that the other country acknowledges its claim to Taiwan and severs official ties with the government of the Republic of China. Chinese officials have protested on numerous occasions when foreign countries have made diplomatic overtures to Taiwan,especially in the matter of armament sales. Political meetings between foreign government officials and the 14th Dalai Lama are also opposed by China, as the latter considers Tibet to be formally part of China.
Much of current Chinese foreign policy is reportedly based on Premier Zhou Enlai's Five Principles of Peaceful Coexistence, and is also driven by the concept of "harmony without uniformity", which encourages diplomatic relations between states despite ideological differences. This policy may have led China to support states that are regarded as dangerous or repressive by Western nations, such as Zimbabwe, North Korea and Iran. China has a close economic and military relationship with Russia, and the two states often vote in unison in the UN Security Council.
Trade Relation-
In recent decades, China has played an increasing role in calling for free trade areas and security pacts amongst its Asia-Pacific neighbors. In 2004, it proposed an entirely new East Asia Summit (EAS) framework as a forum for regional security issues. The EAS, which includes ASEAN Plus Three, India, Australia and New Zealand, held its inaugural summit in 2005. China is also a founding member of the Shanghai Cooperation Organisation (SCO), along with Russia and the Central Asian republics. China became a member of the World Trade Organization (WTO) on 11 December 2001.
In 2000, the United States Congress approved "permanent normal trade relations" (PNTR) with China, allowing Chinese exports in at the same low tariffs as goods from most other countries. China has a significant trade surplus with the United States, its most important export market. In the early 2010s, US politicians argued that the Chinese yuan was significantly undervalued, giving China an unfair trade advantage. In recent decades, China has followed a policy of engaging with African nations for trade and bilateral co-operation; in 2012, Sino-African trade totalled over US$160 billion. China has furthermore strengthened its ties with major South American economies, becoming the largest trading partner of Brazil and building strategic links with Argentina.
Economic history and growth-
From its founding in 1949 until late 1978, the People's Republic of China was a Soviet-style centrally planned economy. Following Mao's death in 1976 and the new Chinese leadership began to reform the economy and move towards a more market-oriented mixed economy under one-party rule. Agricultural collectivization was dismantled and farmlands privatized, while foreign trade became a major new focus, leading to the creation of Special economic Zones (SEZs). Inefficient stste owned enterprises (SOEs) were restructured and unprofitable ones were closed outright, resulting in massive job losses. Modern-day China is mainly characterized as having a market economy based on private property ownership, and is one of the leading examples of state capitalism. The state still dominates in strategic "pillar" sectors such as energy production and heavy industries, but private enterprise has expanded enormously, with around 30 million private businesses recorded in 2008.
Since economic liberalization began in 1978, China has been among the world's fastest-growing economies, relying largely on investment- and export-led growth. According to the IMF, China's annual average GDP growth between 2001 and 2010 was 10.5%. Between 2007 and 2011, China's economic growth rate was equivalent to all of the G7 countries' growth combined. According to the Global Growth Generators index announced by Citigroup in February 2011, China has a very high 3G growth rating. Its high productivity, low labor costs and relatively good infrastructure have made it a global leader in manufacturing. However, the Chinese economy is highly energy-intensive and inefficient; China became the world's largest energy consumer in 2010, relies on coal to supply over 70% of its energy needs, and surpassed the US to become the world's largest oil importer in September 2013. However, China's economic growth and industrialization has damaged its environment, and in the early 2010s, China's economic growth rate began to slow amid domestic credit troubles—international demand for Chinese exports has weakened and this has led to turmoil in the global economy.
In the online realm, China's e-commerce industry has grown more slowly than the EU and the US, with a significant period of development occurring from around 2009 onwards. According to Credit Suisse, the total value of online transactions in China grew from an insignificant size in 2008 to around RMB 4 trillion (US$660 billion) in 2012. Alipay has the biggest market share in China with 300 million users and control of just under half of China's online payment market in February 2014, while Tenpay's share is around 20 percent, and China UnionPay's share is slightly greater than 10 percent.
China in the global economy-
China is a member of the WTO and is the world's largest trading power, with a total international trade value of US$3.87 trillion in 2012. Its foreign exchange reserves reached US$2.85 trillion by the end of 2010, an increase of 18.7% over the previous year, making its reserves by far the world's largest. As of 2009, China owns an estimated $1.6 trillion of US securities. China, holding over US$1.16 trillion in US Treasury bonds, is the largest foreign holder of US public debt. In 2012, China was the world's largest recipient of inward foreign direct investment (FDI), attracting $253 billion. China also invests abroad, with a total outward FDI of $62.4 billion in 2012, and a number of major takeovers of foreign firms by Chinese companies. China's undervalued exchange rate has caused friction with other major economies, and it has also been widely criticized for manufacturing large quantities of counterfeit goods.
China ranked 29th in the Global Competitiveness Index in 2009, although it is only ranked 136th among the 179 countries measured in the 2011 Index of Economic Freedom.In 2011, 61 Chinese companies were listed in the Fortune Global 500. Measured by total revenues, three of the world's top ten most valuable companies in 2011 were Chinese, including fifth-ranked Sinopec Group, sixth-ranked China National Petroleum and seventh-ranked State Grid (the world's largest electric utilities company).
Modern Era-
China is rapidly developing its education system with an emphasis on science, mathematics and engineering; in 2009, it produced over 10,000 Ph.D. engineering graduates, and as many as 500,000 BSc graduates, more than any other country. China is also the world's second-largest publisher of scientific papers, producing 121,500 in 2010 alone, including 5,200 in leading international scientific journals. Chinese technology companies such as Huawei and Lenovo have become world leaders in telecommunications and personal computing, and Chinese supercomputers are consistently ranked among the world's most powerful. Currently China is experiencing a significant growth in the use of industrial robots; from 2008 to 2011, the installation of multi-role robots has risen by 136 percent.
The Chinese space program is one of the world's most active, and is a major source of national pride. In 1970, China launched its first satellite, Dong Fang Hong I. In 2003, China became the third country to independently send humans into space, with Yang Liwei's spaceflight aboard Shenzhou 5; as of June 2013, ten Chinese nationals have journeyed into space. In 2011, China's first space station module, Tiangong-1, was launched, marking the first step in a project to assemble a large manned station by the early 2020s. In 2013, China successfully landed a probe and a rover onto the moon. The rover is expected to last 3 months and the lander up to one year. China plans to collect lunar soil samples by 2017.
