Jiamusi Songjiang International Airport — Jiamusi, China

JMU is the code for Jiamusi Songjiang International Airport, serving Jiamusi in China's northeastern Heilongjiang province, near the Russian border along the Songhua and Amur river systems. Despite its international designation, JMU primarily handles domestic traffic connecting Jiamusi to cities like Beijing and Harbin, though it has hosted limited cross-border flights to Russia given the region's proximity to Khabarovsk. Jiamusi is an agricultural and industrial center in China's far northeast, and the airport supports trade, timber, and grain industries typical of this cold, remote frontier region bordering Russia's Far East.
