Chagang Province is a province in North Korea; it is bordered by China's Jilin and Liaoning provinces to the north, Ryanggang and South Hamgyong to the east, South Pyongan to the south, and North Pyongan to the west. Chagang was formed in 1949, after being demarcated from North Pyongan. The provincial capital is Kanggye. Before 2019, Chagang was the only province of North Korea completely inaccessible to tourists, possibly due to weapons factories and nuclear weapon facilities located there. In 2019 the city of Manpo became accessible to tourists. In May 2018, the province became a "Special Songun Revolutionary Zone" in relations to concealing the nuclear weapon and weapon's factories within the province.

Jilin is one of the three provinces of Northeast China. Its capital and largest city is Changchun. Jilin borders North Korea and Russia to the east, Heilongjiang to the north, Liaoning to the south, and Inner Mongolia to the west. Along with the rest of Northeast China, Jilin underwent an early period of industrialization. However, Jilin's economy, characterized by heavy industry, has been facing economic difficulties with privatization. This prompted the central government to undertake a campaign called "Revitalize the Northeast". The region contains large deposits of oil shale.
