evidence: The People's Republic of China has an area of about 9,600,000 km2 (3,700,000 sq mi). The exact land area is sometimes challenged by border disputes, most notably about Taiwan, Aksai Chin, the Trans-Karakoram Tract, and South Tibet. The area of the People's Republic of China is 9,596,960 km2 (3,705,410 sq mi) according to the CIA's The World Factbook.[1] The People's Republic of China is either the third or fourth-largest country in the world, being either slightly larger or slightly smaller than the United States, depending on how the area of the United States is measured. Both countries are smaller than Russia and Canada and larger than Brazil. [...] Territory and boundary disputes [edit]The territory of China has been defined as a homeland for many different ethnic and racial groups in the country. However, the way that the territory has been defined varies between ethnic groups. In relation to the Han Chinese, the homeland has been defined by national borders which are more or less accepted internationally. This is because the Han Chinese are the largest population and have most influence politically than any other ethnic population in China. To the Han Chinese population, the territory of the country is defined by the regions of Tibet, inner Mongolia, Manchuria, and the Xinjiang Province which is the most western land of China. The Chinese territory is the second largest in land area and also has the longest combined land border in the world. However, there are many other ethnic groups in China that have their own definitions of what concerns the territory of China.
