The total area of the western region is about 6.86 million square kilometers, accounting for about 72% of the total area of China. At the same time, the western region is bordered by 12 countries including Mongolia, Russia, Tajikistan, Kazakhstan, Kyrgyzstan, Pakistan, Afghanistan, Bhutan, Nepal, India, Myanmar, Laos, and Vietnam, with a borderline of more than 18,000 kilometers long, accounting for 91% of China's land borderline length; and the western region faces many countries in Southeast Asia across the sea, with a continental coastline of 1,595 kilometers, accounting for about 10% of China's coastline length. By the end of 2018, the western region has a land area of 6.781589 million square kilometers, accounting for 70.6% of China's total area; and has a population of 379.5587 million, accounting for 27.2% of China's total population. The western region has a vast territory, among which Chongqing is the only first-level administrative region with a per capita GDP that exceeds the national level, reaching RMB 75,828, ranking ninth among the provincial-level administrative regions in China.
