North Korea–Russia border, International land boundary between Russia and North Korea in East Asia
This international boundary runs along the Tumen River and extends across land and water between Russia and North Korea. The border follows the riverbed and continues into the Sea of Japan, where both countries meet.
The Treaty of Peking in November 1860 established the first shared boundary between the Russian Empire and Joseon after Russia gained territories east of the Ussuri River. This border line remained largely unchanged despite later political shifts.
The Tumangang crossing shows different building styles where Korean and Russian elements meet in administrative offices and housing. Visitors can notice these architectural influences along the border station, where both traditions come together.
The railway embankment of Friendship Bridge links Khasan in Russia with Tumangang in North Korea and allows direct train traffic between Moscow and Pyongyang. This railway connection remains the main transport route along this border section.
This boundary is the shortest among all Russian borders with other countries and includes both land and water sections. The border line shifts from river to open sea over a relatively short distance.
