Ali Pulan Airport — Burang Town, China

Few airfields anywhere sit as high as Ali Pulan Airport, which carries the code APJ and lies near Burang Town in a remote corner of the Tibetan Plateau close to where China's border meets Nepal and India. At 13,943 feet, it ranks among the highest airfields in the world, in terrain so extreme that basic infrastructure is difficult to build and maintain. Available data lists zero runways for the field, an unusual gap that likely reflects how hard it is to track activity in such an isolated area rather than any confirmed detail either way. The surrounding Purang region sits near Mount Kailash and Lake Manasarovar, sites of pilgrimage significance, though APJ's current operational status is difficult to verify from public sources.
