China, country of East Asia. It is the largest of all Asian countries. Occupying nearly the entire East Asian landmass, it covers approximately one-fourteenth of the land area of Earth, and it is almost as large as the whole of Europe. China is also one of the most populous countries in the world, rivaled only by India, which, according to United Nations estimates, surpassed it in population in 2023.

India’s history and culture is dynamic, spanning back to the beginning of human civilization. It begins with a mysterious culture along the Indus River and in farming communities in the southern lands of India. The history of India is punctuated by constant integration of migrating people with the diverse cultures that surround India. Available evidence suggests that the use of iron, copper and other metals was widely prevalent in the Indian sub-continent at a fairly early period, which is indicative of the progress that this part of the world had made. By the end of the fourth millennium BC, India had emerged as a region of highly developed civilization.

China has 33 administrative units directly under the central government; these consist of 22 provinces, 5 autonomous regions, 4 municipalities (Chongqing, Beijing, Shanghai, and Tianjin), and 2 special administrative regions (Hong Kong and Macau). The island province of Taiwan, which has been under separate administration since 1949, is discussed in the article Taiwan. Beijing (Peking), the capital of the People’s Republic, is also the cultural, economic, and communications center of the country. Shanghai is the main industrial city; Hong Kong is the leading commercial center and port. Within China’s boundaries exists a highly diverse and complex country. Its topography encompasses the highest and one of the lowest places on Earth, and its relief varies from nearly impenetrable mountainous terrain to vast coastal lowlands. Its climate ranges from extremely dry, desertlike conditions in the northwest to tropical monsoon in the southeast, and China has the greatest contrast in temperature between its northern and southern borders of any country in the world.
