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.
