The DMZ and North Korea

What Is the DMZ?
The Korean Demilitarized Zone (DMZ) is a strip of land running 160 miles (250km) across the Korean Peninsula that serves as a buffer zone between North Korea and South Korea. It passes just 30 miles north of Seoul but is one of the most heavily guarded borders in the world. It divides the Korean Peninsula approximately in half roughly near the original border at 38°N (the 38th parallel), the line that divided North and South Korea at the end of World War II. The Demilitarized Zone incorporates territory on both sides of the cease-fire line as it existed at the end of the Korean War (1950-1953), and was created by pulling back the respective forces 1.2 miles along each side of the line.
The armistice that ended hostilities was signed here in 1953, but, as an official peace treaty was never signed, the two sides have officially been at war for over seven decades.
A Brief History of the DMZ
With Japan’s surrender to the Allies ending World War II in 1945, Korea gained its independence after 35 years of colonization by Japan. The United States and the Soviet Union agreed to a joint temporary occupation of the Korean Peninsula with the US administering the southern part and the USSR administering the northern part.
The zones were split at the 38th parallel, an arbitrary line on the map chosen because it divided the country roughly in half. The division and international administration was supposed to be temporary until Koreans were considered ready to govern by themselves, but with the onset of the Cold War and growing suspicion between the US and USSR the two sides failed to come to an agreement that could establish a unified Korean government and state.
Instead the Republic of Korea (ROK), supported by the United States, was established in 1948 in the south while the Democratic People’s Republic of Korea, supported by the Soviet Union, was established soon after in the north, with both sides claiming sovereignty over the whole peninsula.
On June 25th, 1950, the new North Korean Army invaded across the 38th parallel in an attempt to quickly reunify the Korean peninsula by force. They nearly succeeded, but US-led international intervention changed the course of the war. The conflict devastated the Korean peninsula for three years and killed three million people. After the conflict reached a stalemate close to the 38th parallel, the Korean Armistice Agreement was signed on July 27th, 1953 between the United Nations Command, North Korea, and China to establish a ceasefire.
Each side agreed to move their troops back 2,000m (1.24 miles) from the front line to create a demilitarized zone, establishing a 2.5 mile wide buffer with established rules of conduct. The Military Demarcation Line (MDL) runs through the middle of the DMZ and indicates where the front was when the agreement was signed.
More than seven decades later, both sides still stand guard on either side of the DMZ, two large armies on constant alert for potential aggression from the other side. The arbitrary division that in 1945 everyone thought would be temporary has ended up with one of the most impermeable borders in human history.
The Security Status at the DMZ
The border between North and South Korea is one of the most heavily guarded stretches of land in the world. The DMZ, littered with scores of mines and barbed-wire fences, is almost impossible to cross, except at the Joint Security Area (JSA). The JSA is a special zone inside what is known as the "truce village" of Panmunjom, about 35 miles north of Seoul. Every year, when it is open to tourists, thousands of people visit the JSA for a chance to see North Korean soldiers standing at attention just dozens of feet away and to officially step into North Korean territory inside a United Nations Command administered conference room that straddles the military border.
A visit there feels like military theater, with stern warnings from the South Korean soldiers under United Nations Command not to make gestures at their counterparts. Since demarcation, the DMZ has had numerous incidents and incursions by both sides, although the North Korean government typically doesn’t acknowledge direct responsibility for any of these incidents.
Human Rights and Repression in North Korea
North Korea is one of the world's most repressive states. The government restricts all civil and political liberties for its citizens, including freedom of expression, assembly, association, and religion. It prohibits all organized political opposition, independent media, civil society, and trade unions. The government routinely uses arbitrary arrest and punishment, torture in custody, forced labor, and executions to maintain fear and control across the country. Beyond the DMZ, North Korea is a highly controlled country where human rights are routinely violated.
The international community has continued to press the North Korean government to expand its engagement with United Nations human rights mechanisms, including action on findings of the UN Commission of Inquiry (COI). The COI report shows that the country has committed crimes against humanity including extermination, murder, enslavement, imprisonment, rape, sexual violence, forced abortion, and other heinous crimes. The citizens of North Korea require a lot of help and support from the international community in order to attain a better life.
The North Korean people face a brutal and repressive government that isolates them from the world and denies their most basic human rights. But you can help to create change. At Liberty in North Korea (LiNK), we help North Korean refugees escape through a 3,000-mile secret rescue route and empower North Koreans who have reached freedom to be changemakers, advocates, and leaders on this issue.
You can help make a difference in the lives of North Korean citizens by learning more about our organization, raising funds, advocating for the people of North Korea, starting a rescue team, or making a donation today!
Interview with Charles - North Korean Student at Coding Dojo

Charles escaped from North Korea and made the dangerous journey to safety without the help of a rescue. He resettled to the US in 2012, completing high school and soon after taking the opportunity to participate in a rigorous coding bootcamp through a partner of Liberty in North Korea, Coding Dojo. Charles is now attending community college and pursuing his own coding project. We had a chance to meet with Charles this summer to learn more about his life in North Korea and his new coding passion. Read the interview is below. Charles is also fundraising for rescues with us!
LiNK: Why did you choose to resettle to the US?
Charles: I was born between a North Korean mom and a Chinese dad, which put me in a difficult situation. I wasn’t accepted into South Korea because my Dad is Chinese, even though I had proof of having been captured once in China for being a North Korean refugee. So I applied for refugee status through the United Nations and resettled in the US.
LiNK: You attended Coding Dojo’s coding Bootcamp earlier this year - so cool! Between coding language, English, and borrowed words in Korean, which was the hardest language to learn?
Charles: Coding was hard. You have to know the terms while learning the specific coding language, so that was a challenge. I’m still teaching myself the parts of coding that I find difficult. As for borrowed words in Korean, I didn’t know those existed at all until I started to talk to more Koreans in the US. Borrowed words frequently came up, and I would have to ask people around me to explain the words that I couldn’t understand; part of the challenge was how the same word is pronounced differently in Korean and in English. Shortened words in Korean were tough to learn as well.
LiNK: What’s your favorite thing about programming?
Charles: My favorite thing about programming is I have finally discovered what I truly want to do with my life. I used to want to be a doctor one day, a cop the next day, and maybe a week later, I would want to join the army. Coding first became my hobby and thanks to Coding Dojo, it became something I want to make a career out of. It’s a lot of fun. But aside from that, I’ve also met good friends and instructors at Coding Dojo. I think it’s safe to say coding made me pull a 180 in life. I’m set on computers for now.
LiNK: Can you tell us about a project you’ve been working on?
Charles: Sure. I’ve been working on a project using MEAN stack to make an auction platform for ideas. Users can present ideas, sell ideas, buy ideas… You could say that it’s similar to Ebay in a way, but I think at this stage it’s important to emulate what other people have made to explore and learn about various successful models rather than trying to create something entirely new and different. With the current version, users can upload an idea onto the platform, but there’s been glitches in the idea being transferred to the the auction page. So that’s something I’ve been struggling with, but I think I’m going to finish it pretty soon.
LiNK: How do you get into computer programming as a career in North Korea?
Charles: I’m not sure because I don’t have any friends who went to university, although I do have a relative who was able to go. Most students who go to university come from wealthy families or are people who have been able to make a good amount of money from market activities, and they might find that kind of job. But in North Korea a lot of occupations are passed down from your parents, for example if you’re a politician then your children will also likely become politicians.
LiNK: After coding, what do you like to do in your free time?
Charles: I’m usually at the gym working out. If it’s breezy and not too hot outside, I go to the park and listen to music. You can find me sitting on a bench with my headphones on.
LiNK: What kinds of things do you think about when you’re at a park listening to your music?
Charles: Usually I think about memories from North Korea. When I’m busy my mind is preoccupied with work, but when I have more time on my hands I often think back on my life in North Korea -- both the good days and the hungry days.
LiNK: Can you share one of your favorite memories with us?
Charles: Sure. I had a lot of friends back in North Korea, and we were always outdoors in nature. I lived near Daedong River, so every Sunday, five to six friends of mine and I would have cookouts near the river. We would get rice, a pot, and some firewood to make porridge. Would I do that here? Probably not. I could try, but I think being with my friends was what made it memorable and special. Even when we were hungry, we were hungry together.
LiNK: That sounds really nice. Have you found any foods that you like to eat here?
Charles: Subway! I love sandwiches. My go-to Korean food is Kimchijiggae. I also like Vietnamese noodles — Pho.
LiNK: Cool. What are three things you want to accomplish by the end of this year?
Charles: First is completing my programming project, the Idea Auction project that I mentioned earlier. Second is getting accepted into the community college that I’m applying to. And third would be keeping in good health!
LiNK: Those are some solid goals. You drive Uber sometimes, right? When you’re talking with riders, do you share that you’re from North Korea?
Charles: Well, not a lot of people in the US are aware about North Korea. They say, “Where are you from?” So I would say, “I’m from North Korea,” and they go, “How is it there?” Haha. So I tell them that North Korea is the counterpart of South Korea. The funny thing is that they might not be familiar with North Korea, but they know what I’m talking about when I say the name Kim Jong Un. Then, they don’t believe me and say it’s impossible to escape. When I share my story, they’re very surprised. A lot of my customers stick around to listen to my story even after we’ve arrived at the destination. Even if it’s late at night, people don’t get out of my car until I finish my story.
