Shiwei, Inner Mongolia

Mengwu Shiwei (Chinese: 蒙兀室韦苏木; Russian: Сомон Мынъу-Шивэй) is a sum (a type of township-level division) under the administration of Ergun City, northeastern Inner Mongolia, situated directly on the border with the Russian-Siberian Far East. Shiwei is known for its use of Russian architecture, including many domed buildings in the Russian style.

The township is one of the main border crossings between China and Russia, lying on one side of the Ergune River. On the opposite bank lies the Russian village of Olochi, Zabaykalsky Krai, which connects to Shiwei via the Friendship Bridge.
