Arxan Yi'ershi Airport (IATA: YIE, ICAO: ZBES) is a regional airport serving Arxan City in the Hinggan League of Inner Mongolia Autonomous Region, China. It connects this remote border area to major Chinese cities, supporting both tourism and local commerce. The airport serves as an important access point for visitors to the Arxan National Forest Park and the surrounding volcanic geological park, which are significant tourist attractions in northeastern China. Given the region's cold climate and seasonal tourism patterns, flight frequencies tend to peak in summer months. As a smaller regional facility, the airport handles a modest volume of passengers and operates limited scheduled services primarily to destinations within China such as Beijing and Hohhot.
