Sonbong County

Sonbong County, formerly called Unggi (Chosŏn'gŭl: 웅기, Hancha: 雄基), is a subdivision of the North Korean city of Rason. It is located at the northeastern extreme of North Korea, bordering Russia and China. It lies on Unggi Bay, an extension of the Sea of Japan (East Sea of Korea). A uranium mine is allegedly located there, as is a 200 megawatt oil-fired power plant. The word Sonbong means "Vanguard" in Korean.
The Sonbong Revolutionary Site there is dedicated to a visit by Kim Jong-suk in November 1945 "upholding the policy of building a new country advanced by President Kim Il Sung" after the liberation of Korea. It includes the Sonbong Revolutionary Museum, a monument to the historic site, and the house where she stayed.
