Jiansanjiang Shidi Airport — Jiansanjiang, China

Jiansanjiang Shidi Airport (JSJ) serves Jiansanjiang, a agricultural administrative area in Heilongjiang province in northeastern China, near the Russian border. The airport supports a region dominated by large-scale state farm operations and rice cultivation in the Sanjiang Plain, one of China's major grain-producing areas. JSJ provides domestic flight connections that help link this remote agricultural district to larger Chinese cities, reducing the isolation of a region historically reliant on rail and road transport across long distances. As with many airports built in China's push to improve regional connectivity in the 2010s, JSJ primarily handles smaller narrow-body aircraft and modest passenger volumes tied to local government and agribusiness travel.
