China–North Korea border
border between the People's Republic of China and North Korea
The China–North Korea border is an international border separating China and North Korea, extending from Korea Bay in the west to a tripoint with Russia in the east. The total length of the border is 1,352 kilometers (840 mi). The current border was created by two secret treaties signed between China and North Korea in 1962 and 1964.
Geography
From west to east, the two countries are divided by three significant geographical features: the Yalu River, Paektu Mountain, and the Tumen River.
Dandong, in the Liaoning Province of China, on the Yalu River delta, is the largest city on the border. On the other side of the river is the city of Sinuiju in North Pyongan Province, North Korea. The two cities are situated on the Yalu river delta at the western end of the border, near the Yellow Sea. Their waterfronts face each other and are connected by the Sino-Korean Friendship Bridge. Both nations have invested in new border facilities, including the long-delayed New Yalu River Bridge and updated customs infrastructure at Dandong, Quanhe, and Nanping from the North Korean border.
There are 205 islands on the Yalu River.
