China–North Korea border

The China–North Korea border is the international boundary between northeastern China and North Korea, running mainly along the Yalu and Tumen rivers.

Yalu River: A river in East Asia that forms much of the boundary between China and North Korea. Its lower course marks the border’s western and central reaches.
Qing dynasty: China’s last imperial dynasty, which ruled from 1644 to 1912. Qing control and frontier policies shaped the region before modern borders.
China–North Korea relations: The political, economic, and security relationship between China and North Korea. Border access is one of the relationship’s most direct practical dimensions.
Paektu Mountain: A volcanic mountain on the China–North Korea border, known in China as Changbai Mountain. The border crosses a landmark whose national symbolism exceeds its local geography.
China–North Korea border security: The policing and military management of the frontier between China and North Korea. Security measures determine how tightly people and goods can cross.
Tumen River: A river in East Asia that flows along the boundary between China, North Korea, and Russia. Its course marks the border’s eastern section.
Joseon: A Korean dynasty that ruled the Korean Peninsula from 1392 to 1897. Joseon’s northern frontier preceded the present China–Korea boundary.
China–North Korea trade: The exchange of goods between China and North Korea, dominated by China’s role as North Korea’s largest trading partner. Most legal bilateral commerce passes through border links and nearby ports.
Heaven Lake: A crater lake atop Paektu Mountain, shared by China and North Korea. Its divided waters make the border visible at a celebrated natural site.
North Korean refugees: People who flee North Korea and seek protection or permanent residence elsewhere. Their routes and risks are shaped by China’s treatment of crossers.
