China is the largest country located entirely within Asia by total area.
China covers about 9.6 million square kilometres in East Asia. Its territory ranges from the high Tibetan Plateau and the Himalayas to broad deserts, fertile river plains and long Pacific coastlines. It borders fourteen countries, the joint-highest number for any country with Russia.
China is usually listed as the world’s third-largest country by total area in standard comparisons, behind Russia and Canada. Rankings can vary slightly because countries measure inland waters and disputed areas differently. China’s land area, however, is consistently among the world’s largest.
Russia is larger in Asia overall, but it is transcontinental because its territory also lies in Europe. That is why China is the clearest answer when the question specifies a country entirely within Asia. China is also the world’s most populous country or second-most populous, depending on the year and dataset used.
