Huatugou Airport — Mengnai, China

HTT designates Huatugou Airport, a high-altitude facility located near Mangnai in the remote Qaidam Basin of Qinghai Province, China. This is one of the more obscure airports in western China, built primarily to serve oilfield workers and industrial activity in the sparsely populated basin region, which sits at considerable elevation on the Tibetan Plateau's edge. The surrounding terrain is arid and largely uninhabited, making air travel through HTT far more practical than long overland journeys. Flights from HTT typically connect to larger hubs like Xi'an or Xining. The airport reflects China's broader strategy of building small regional airstrips to support extraction industries in far-flung interior provinces.
