China is bordered to the north by Russia and Mongolia; to the east by Korea (Dem Rep), the Yellow Sea and the South China Sea; to the south by Vietnam, Laos, Myanmar, India, Bhutan and Nepal; and to the west by India, Pakistan, Afghanistan, Tajikistan, Kyrgyzstan and Kazakhstan. China has a varied terrain ranging from high plateaux in the west to flatlands in the east; mountains take up almost one-third of the land. The most notable high mountain ranges are the Himalayas, the Altai Mountains, the Tian Shan Mountains and the Kunlun Mountains. On the border with Nepal is the 8,848m (29,198ft) Mount Qomolangma (Mount Everest). In the west is the Qinghai/Tibet Plateau, with an average elevation of 4,000m (13,200ft), known as ‘the Roof of the World’. At the base of the Tian Shan Mountains is the Turpan Depression or Basin, China’s lowest area, 154m (508ft) below sea level at the lowest point. China has many great river systems, notably the Yellow (Huang He) and Yangtze River (Chang Jiang, also Yangtze Kiang). Only 10% of all China is suitable for agriculture.
