China is the largest sovereign country that lies entirely in Asia.
China has a total area of roughly 9.6 million square kilometres, making it Asia’s largest country when countries that extend across more than one continent are excluded. Russia is larger, but its territory lies in both Europe and Asia, so it does not meet the wording of this question.
China occupies much of eastern and central Asia, extending from the Pacific coast to the highlands and mountains of the west. Its landscape includes deserts, plateaus, grasslands, river plains, and major mountain ranges such as the Himalayas.
China is also one of the world’s most populous countries. Its large area contains many climate zones, from tropical regions in the south to cold alpine environments in Tibet and the far north. The country shares land borders with 14 sovereign states.
