The Suifenhe–Manzhouli Expressway (Chinese: 绥芬河－满洲里高速公路), commonly referred to as the Suiman Expressway (Chinese: 绥满高速公路) is an expressway that connects the cities of Suifenhe, Heilongjiang, China, and Manzhouli, Inner Mongolia. When fully complete, it will be 1,520 km (940 mi) in length. Currently, the expressway is complete in its entirety in Heilongjiang Province, from Suifenhe to just northwest of Qiqihar. The section in Inner Mongolia, from Arun Banner to Manzhouli, is in the planning stage and not yet built.
Both ends of the expressway terminate at border towns with Russia. Suifenhe is the location of a border crossing with Russian locality of Pogranichny in Primorsky Krai. Manzhouli is across the border from Zabaykalsk in Zabaykalsky Krai. The expressway parallels much of China National Highway 301, a highway that connects Suifenhe and Manzhouli, and the Trans-Manchurian Railway between the two cities.
