China, officially the People's Republic of China, is a unitary sovereign state in East Asia and the world's most populous country, with a population of over 1.381 billion.
With an area of about 9.6 million square kilometers, it is the second largest country in the world in terms of land area.
The country consists of more than 22 provinces and its capital is Beijing.
The country's landscape varies from forests, steppes and deserts (Gobi and Taklamakan) in the dry north near Mongolia and Siberia in Russia to subtropical forests in the humid south near Vietnam, Laos and Burma.
The terrain in the west is rugged and at high altitude, where the Himalayas and the Tian Shan Mountains lie, forming China's natural borders with India and Central Asia.
In contrast, the eastern coast of the mainland is low-lying and has a long coastline of 14,500 kilometers, bordered to the southeast by the South China Sea and to the east by the East China Sea, outside of which lie Taiwan, Korea, and Japan.
Ancient Chinese civilization is one of the oldest in the world, flourishing in the fertile Yellow River basin that flows through the North China Plain.
