North Korea–Russia border

The border between Russia and North Korea, according to the official Russian definition, consists of 17 kilometres (11 mi) of "terrestrial border" and 22.1 km (12 nautical miles) of "maritime border". It is the shortest of the international borders of Russia.

The terrestrial boundary between Russia and North Korea runs along the fairway (thalweg) of the Tumen River and its estuary, while the maritime boundary separates the two countries' territorial waters in the Sea of Japan.

The principal border treaty was signed on April 17, 1985. A separate, trilateral treaty specifies the position of the tripoint of the borders of Russia, North Korea, and China. The North Korea–Russia and China–North Korea borders run along the middle of the Tumen River, while the China–Russia border approaches the junction point overland from the north. Because the theoretical tripoint is in the middle of the river, where it would be impractical to install a border monument, the agreement provides instead that the three countries install border monuments on the riverbank, and that the position of the tripoint be determined with respect to those monuments.

The administrative unit on the Russian side of the border is the Khasansky District of Primorsky Krai; on the Korean side, it is the city of Rason. The main Russian border guard station in the area is Peschanaya.

There is one crossing on the North Korea–Russia border: the Friendship Bridge over the Tumen River, 800 metres southwest of the train station in Khasan, Russia. On the North Korean side, the border train station is at Tumangang. The crossing is railway-only, used by freight and passenger trains. There is no border crossing for road vehicles or pedestrians.
