Ryu Seong-hyeon (Korean: 류성현) is a North Korean defector and former soldier who gained international attention after his rare defection across the Demilitarized Zone (DMZ) to South Korea in 2019.[1][2] He is known for his advocacy for human rights and Korean unification, and he serves as a media commentator on North Korean military affairs.[2][3]

Early life and Military Service

Ryu was born in Kangwon Province, near the inter-Korean border in North Korea.[2] As a teenager, he found a South Korean propaganda leaflet which claimed the North had started the Korean War, contradicting official North Korean history.[2] This incident planted a "seed of doubt" about the regime's narratives and motivated him to seek a life in South Korea.[2]

He served for seven years as a driver in the North Korean air force in South Hamgyong Province.[2] During his service, he endured severe living conditions, including poor food (eating mushy rice mixed with corn and rarely having meat) and physically demanding labor.[2] He later stated that at the time, he would have even volunteered to go to war in Ukraine if it meant better food.[2]

Defection to South Korea

In 2019, Ryu made a rare and dangerous defection by running across the heavily fortified and mine-riddled DMZ.[1] He successfully crossed the border despite coming under fire from North Korean troops; he later recalled hearing twelve bullets pass just a meter over his head.[2]

Upon his defection, he weighed only around 110 lbs due to malnutrition, a condition common among North Korean soldiers.[1]

Life in South Korea and Activism

After arriving in South Korea, Ryu adapted to his new life and became a university student.[2][4] He became involved in advocacy work, promoting human rights and a unified Korea through organizations like the Global Peace Foundation.[1]

Ryu has become a prominent media commentator, providing insights into the lives and mindsets of average North Korean soldiers to international outlets, including the BBC, ABC News, and the Wall Street Journal.[4]

Russia-Ukraine War

Ryu gained significant attention in late 2024 and early 2025 for his analysis of the deployment of North Korean troops to the Russian frontlines in Ukraine.[5] He has stated that North Korean soldiers are told their families will face execution if they are captured alive, leading many to prefer suicide over surrender.[6][7]

He has described the North Korean soldiers sent to Russia as "cannon fodder" who are often young, underfed, and cut off from the outside world.[2] He confirmed the authenticity of a diary found on a deceased North Korean soldier by Ukrainian forces, identifying the handwriting and phrasing as distinctly North Korean.[2]
