Both are among the most closed states in the world, and both were shaped by a single family's cult of personality, but they differ in important ways.
What they share
- Personality cults: Turkmenistan's first president, Saparmurat Niyazov ('Turkmenbashi'), had his own book, the Ruhnama, placed alongside religious texts and renamed months after himself and his mother. North Korea's Kim dynasty built the Juche ideology and a cult around Kim Il Sung.
- Dynastic succession: Kim Jong Un succeeded his father, and in Turkmenistan Gurbanguly Berdimuhamedov handed the presidency to his son Serdar in 2022.
- Control of information: Both keep tight limits on the press, the internet and foreign travel. Independent reporting from inside either country is very hard to get.
- Forced labour allegations: Turkmenistan's state-organised cotton harvests have been documented by rights groups as forced labour. North Korea's system of state labour and prison camps is documented in the UN Commission of Inquiry report of 2014.
Where they differ
- Nuclear weapons and sanctions: North Korea has nuclear weapons and faces broad UN and other sanctions. Turkmenistan has neither.
- Economy: Turkmenistan sits on some of the world's largest natural gas reserves and sells gas to China and others through pipelines. North Korea's economy is much weaker, and China is its main trading partner.
- Outside contact: Turkmenistan has a neutral status recognised by the UN in 1995, keeps diplomatic ties with many countries, and has a few tourist routes. North Korea is more isolated and tourism is tightly managed.
