"South Hamgyeong Province" or "Hamgyeongnam-do" ([hamɡjʌŋ namdo]) is, according to South Korean law, a province of the Republic of Korea, as the South Korean government formally claims to be the legitimate government of whole of Korea. In reality, the area constituting the province is under the effective jurisdiction of both North Korea and PRC.
As South Korea does not recognize changes in administrative divisions made by North Korea, official maps of the South Korean government shows South Hamgyeong Province in its pre-1945 borders. The area corresponds to North Korea's South Hamgyong Province, as well as parts of Ryanggang Province, Chagang Province, Kangwon Province and PRC's Jilin Province.
To symbolize its claims, the South Korean government established The Committee for the Five Northern Korean Provinces as an administrative body for the five northern provinces. A governor for South Hamgyeong Province is appointed by the President of South Korea.
Hamgyeongbuk-do is divided into 3 cities (si) and 16 counties (gun).
