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!
North Korean Agents of Change | Seohyun’s Story
It was an ordinary taxi ride. The driver struck up a casual conversation, commenting about the weather, asking what I do. At some point I shared that I was from North Korea- after two years studying abroad in China, I was used to the curiosity that typically followed.
But instead, the driver pointed to a picture of Deng Xiaoping on his rear view mirror. He explained how China was able to open up, reform, and get out of poverty. Then he asked, very pointedly, “why hasn’t your leader done the same thing, and left the people to starve?”
That was the moment when over two decades of brainwashing finally began to unravel.
My name is Seohyun Lee and I’m an advocate for the North Korean people. I was born and raised in Pyongyang, North Korea’s capital. This is my story.

I had the unique opportunity to study in China because of my father’s position and commitment to the regime. He was a high-ranking overseas economic officer, and was allowed to bring his children if he could afford all living expenses and tuition. At first, my brother and I alternated our time in China- one member of the family always had to stay behind as a hostage. But in 2010, the regime adopted a more open policy that allowed entire families to be together, so we were all finally reunited.
Growing up in Pyongyang, the circle of elites was very small. Every so often, you’d hear about a family that was sent to a political prison camp because someone’s son or daughter acted out of line. I restrained myself from an early age because I knew my actions and words could threaten the safety of my loved ones.
So even after learning the truth about North Korea, there was not much I could do. I hoped that because Kim Jong Un was a younger guy who had also studied abroad in Switzerland, our generation could change North Korea with more open-minded leadership. But it turned out to be even worse than before.

My fondest memories in China are with my roommate, another North Korean exchange student. She was my best friend and like a big sister to me. We traveled, shopped, and shared many delicious meals together. When I was sick with the flu, she took me to the hospital and stayed by my side until my IV was finished. During those years, she was like another part of me.
I’ll never forget the last time I saw her. I watched helplessly as she was forcefully taken from our dorm room by North Korean officers. Her father was executed for being associated with Kim Jong Un’s uncle, and she was sent to a political prison camp with the rest of her family.
That day, my eyes were opened to the brutality of the regime. To them, we were just like batteries to be thrown away when used up. Our lives never mattered.
I miss her so much. I really want to believe that she’s still alive, and one day I can meet her again.

What happened to my roommate was not an isolated incident. Starting in 2013, there were countless executions and purges happening in North Korea under the Kim Jong Un regime. My family and I lost many friends, neighbors, and respected colleagues. While dealing with great loss, we also knew that at any moment, we could be next.
It was a crisp fall evening. My family and I drove to a park and left our phones in the car. We walked until we were out of earshot, and finally talked openly about what we should do.
My father worked hard because he had hope that improving the economy would better the lives of the people. But we realized that under the current system, what he desired was not possible. So in order to save ourselves and also bring change to the country, we decided to leave in October 2014.

My dad still has a huge heart for North Korea. But I want to make sure that his love for the country is separated from being loyal to the regime. Back in North Korea, he worked tirelessly for a better future for the people. Today, he’s working towards the day where every North Korean has guaranteed human rights and three meals a day.
Like a lot of Asian parents, my father is not good at outwardly expressing affection. The way it manifests is through constant nagging. I didn't get it when I was young, but as I’ve gotten older, I now understand that's how he shows his love and care for us.
There have been moments when I’ve wished I was born in a different country. But when I think about my family, I never regret it.
My dad has been our foundation, my mom is the most thoughtful and perfect woman I know, and my brother has always looked out for me. We all love and support each other, especially after going through so much together.

This fall, I started my graduate studies at Columbia University. I never imagined that I would be chasing my dreams here in America. I hope to use everything I learn to bring a better future for the North Korean people, even after they become free from the current regime.
When my family and I left China, we came here not only to save ourselves, but with ambitions to change the system and bring freedom. Many people have not been as lucky as I have, so I feel it is my privilege and obligation to be a voice for my fellow North Koreans. I believe many of them are already opening their minds to the outside world.
We need to let them know that there’s a global movement of people who have their backs, and we can’t wait for them to be free.

It’s #GivingTuesday, the year’s biggest day of generosity! As we work towards creating the best version of our world, we’re making sure it’s one where every North Korean is free.
Your support will allow us to continue investing in North Korean agents of change - people like Seohyun - who are leading this movement and transforming one of the most repressive countries in the world.
Through access to English language programs, mentorship, scholarships, and more, you can help us support more North Korean refugees as they pursue their dreams and impact this issue.
