evidence: Ryanggang Province (Ryanggangdo; Korean: 량강도; MR: Ryanggang-do, Korean pronunciation: [ɾjaŋ.ɡaŋ.do]) is a province in North Korea. The province is bordered by China (Jilin) to the north, North Hamgyong to the east, South Hamgyong to the south, and Chagang to the west. Ryanggang was formed in 1954, when it was separated from South Hamgyŏng. The provincial capital is Hyesan. In South Korean usage, "Ryanggang" is spelled and pronounced as "Yanggang" Korean: 양강도; RR: Yanggang-do, Korean pronunciation: [jaŋ.ɡaŋ.do]). [...] Although all of North Korea is economically depressed after Soviet dissolution, Ryanggang province, along with neighboring North Hamgyong and South Hamgyong provinces, are the poorest, forming North Korea's "Rust Belt" of industrialized cities with factories now decrepit and failing. The worst hunger of the 1990s famine years occurred in these three provinces, and most refugees into China come from the Rust Belt region.[3] [...] Ryanggang is divided into 2 cities (si) and 10 counties (kun). Each entity is listed below in English, Chosŏn'gŭl, and Hanja.
