Yangjiang Heshan Airport is a regional civil airport located in Guangdong Province, China, serving the city of Yangjiang. It operates under the ICAO code ZGYJ and is intended to improve air connectivity for a coastal city historically reliant on nearby Guangzhou Baiyun International Airport. The airport serves a relatively small catchment area in western Guangdong and handles limited domestic routes. It forms part of China's broader strategy to develop regional aviation infrastructure in smaller cities to support economic growth. Detailed operational data, including precise opening dates and current airline partnerships, are not widely documented in publicly available sources, reflecting its status as a smaller regional facility.
