The DMZ and North Korea

What Is the DMZ?
The Korean Demilitarized Zone (DMZ) is a strip of land running across the Korean Peninsula that serves as a buffer zone between North Korea and South Korea. The DMZ is a de facto border barrier and divides the Korean Peninsula approximately in half. It roughly follows latitude 38°N (the 38th parallel), the original demarcation line between North Korea 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.
Upon the creation of the Democratic People's Republic of Korea (DPRK, also known as North Korea) and the Republic of Korea (ROK, or South Korea) in 1948, the DMZ became a de facto international border and one of the tensest fronts in the Cold War. The DMZ is about 160 miles long and approximately 2.5 miles wide. The truce that ended hostilities was signed here in 1953, but, as an official peace treaty was never agreed to, the two sides have still officially been at war for over sixty years. There are no troops in the DMZ itself, although both sides of the 2.5-mile strip of land separating the Koreas are the most heavily armed in the world.
A Brief History of the DMZ
Even as North Korea and South Korea marched together in a show of political solidarity at the opening ceremony of the 2018 Winter Olympic Games in Pyeongchang, and a newly combined Korean women's hockey team competed as one nation, there remains one unmistakable reminder of the chasm between the two nations. The DMZ was established in 1953 as part of the Korean Armistice Agreement between the United Nations, North Korea, and China to end the Korean War. In essence, it is a line in the sand that extends the entire 160-mile length of the Korean Peninsula, passing just about 50 miles from the Olympic village in Pyeongchang.
The 38th parallel north was the original boundary between the United States and the Soviet Union’s briefly held administration areas of Korea at the end of World War II. Both the North and South remained dependent on their sponsor states from 1948 to the outbreak of the Korean War. This conflict, which claimed over three million lives and divided the Korean Peninsula along ideological lines, started on June 25th, 1950, with a full-front DPRK invasion across the 38th parallel, and ended in 1953 after international intervention pushed the front of the war back to near the 38th parallel.
The Armistice Agreement for the Restoration of the South Korean State was signed on July 27th, 1953, and resulted in the creation of the DMZ as each side agreed to move their troops 1.2 miles back from the front line, establishing a 2.5-mile wide buffer zone. The Military Demarcation Line (DML) goes through the center of the DMZ and indicates where the front was when the agreement was signed. Owing to this theoretical stalemate and genuine hostility between North and South Korea, large numbers of troops are still stationed along both sides of the buffer zone. Each side holds constant guard against potential aggression from the other side, even 68 years after its establishment. The armistice agreement clearly explains the number of military personnel and what kind of weapons are allowed in the DMZ.
DMZ as a Cultural Site
Borders are usually geopolitical boundaries that mark the legal limits of a nation's sovereignty, and are often of interest to tourists for the meeting of cultures that occur therein, rather than for their divisive functions. The DMZ acts as a unique cultural site for the two Koreas, and this is seen as an attraction for tourists to the region. They recognize borderlands as symbolic cultural landscapes loaded with iconic sites and attractions that reflect the public memory. This memory is often focused on the past, ongoing wars, or territorial conflicts that have formed the border.
Tourism can act as a force of peace, a mechanism that promotes empathy and supports reconciliation processes between nations. In addition to fostering cultural exchange, research suggests that countries with open and sustainable tourism industries enjoy higher levels of peace, economic prosperity, and resilience. However, the highly regulated movement of Korean nationals on both sides of the DMZ usually limits the peace-building opportunities that are traditionally associated with an exchange of culture. This strict control of the border along with the careful curation of museums and war memorials has allowed each side to write its own version of history.
In the area, there are three small conference buildings administered by the United Nations in the Joint Security Area, all painted the international organization's signature blue, while North Korea controls three others. On the North side, a building called Panmon Hall looms, while on the South stands Freedom House, which hosts Red Cross and visitor activities. The Freedom House was intended to be a meeting area for separated families from both countries, but the North declined, fearing that its citizens might defect.
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 nightmarishly difficult to cross, except the Joint Security Area (JSA). JSA is a special buffer zone inside what is known as the "truce village" of Panmunjom, about 35 miles north of Seoul. Every year, hundreds of thousands of people usually 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 administered conference room that literally straddles the military border.
A visit there feels like a military theater, with the stern warnings from the South Korean soldiers under United Nations (UN) command not to make gestures at their counterparts. Since demarcation, the DMZ has had numerous cases of incidents and incursions by both sides, although the North Korean government typically never acknowledges direct responsibility for any of these incidents. This can be a highly risky place if mutual respect is not maintained from both sides.
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 of crimes, torture in custody, forced labor, and executions to maintain fear and control across the country. Besides the DMZ, North Korea is a highly controlled country where human rights are ignored.
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!
"And We Will Be Free" Jo Eun's Story

The Tumen River starts on the slopes of Mount Paektu. Its icy waters twist and turn for hundreds of miles before slipping off the Korean peninsula and into the East Sea. In the summer, the reeds along the river grow taller than me and yellow and white wildflowers blossom along the banks.
I was born next to the Tumen. I grew up playing on its rocky shore, splashing and swimming in its waters. In the winter my friends and I would race up and down on ice skates. For my mom’s birthday, we would catch fish and cook them under the shade of a tree. I have many fond memories of the Tumen.
But I want to tell you about the times I tried to cross it. Because those times nearly cost me my life. The Tumen is more than a river. It’s a razor that cuts its way between North Korea and China. It’s a meandering border of shallow water that you can wade across in minutes. And in the winter, you can slide across its ice even faster. Just like I did for the final time last year.
I decided to cross the Tumen for the first time 8 years ago. I did it for my daughter. Her name is Hee-Mang which means hope in Korean. As a baby she was so calm and happy. I would adore her sweet smile and when I held her it melted away the pain and heartache of life in North Korea.
When she started saying “mommy” and took her first steps I was ecstatic. Her laughter was precious and her eyes beamed with life. But I was always worried that I couldn’t be a good mother.
I wanted to give Hee-Mang a better life than I had.
I knew of friends who had defected to South Korea. They sent money back and their families seemed to be much better off. So I decided to leave North Korea to make money and eventually bring Hee-Mang to freedom.
The first time I tried to cross the Tumen I didn’t get far. The broker I hired to help me escape worked for the secret police. They dragged me out of my hiding spot and sent me off to a detention center.
That’s where I first learned how much freedom would actually cost.
It was March and a pregnant woman arrived after being arrested in China. The courtyard of the detention center was covered in snow and ice. The guard forced her to walk around on her hands and knees in the snow for hours. He mocked her, saying that you got pregnant with the baby of a dog so you have to walk like a dog. Then he’d pry open her mouth and spit in it. If any of us cried or pleaded for him to show mercy, he’d force us to do the same.
When we weren’t crammed into our cells, sleeping on a filthy floor, we were forced to work. From 5am to 11pm we’d go into the mountains to gather firewood. The labor left your hands raw with blisters and the cold bit at your fingers and toes.
We were only fed a quarter of an ear of corn per meal. It was never enough and the hunger clawed at our stomachs. People grew so hungry that the guards had to drag them from the toilets so they wouldn’t eat their own feces. Some mornings I woke up to find one of my cellmates stiff and lifeless. We’d march off to gather firewood and their pale body just laid there, their cheeks hollowed out from the hunger.
One afternoon, I decided to escape. I walked over to an unlocked window, flung myself out the opening, and started running. For 4 days I trekked through the wilderness until I reached my hometown. But from the hill above my parent’s house I could see the security agents waiting for me. I had no place to go and I was terrified of being caught. I wanted to see Hee-Mang again but it was too dangerous.
So I returned to the Tumen River. It was summer now – when the rains come up from the south and the river swells into a rage. It was pouring the night I crossed and the current swept me downstream. I waded out on the other side and into China. A Chinese family gave me food and dry clothes and when I told them I needed to go to South Korea, they connected me with a broker.
I moved south through China with a group of 12 other North Korean refugees. We were nearly to Southeast Asia when we stopped to spend the night in a small motel. There were two young boys with us. They were 9 and 10 and they were running around the motel yelling in Korean. The receptionist must have overheard them.
I was on the fourth floor when I heard police sirens outside. I raced to the window but it was bolted shut with metal bars. The Chinese police barged into the room and handcuffed all of us.
There was a teenage girl with us whose mom was waiting for her in South Korea. She wailed and pleaded with the Chinese police: “Please please, can I just go to be with my mom. She’s going to be so worried about me. I just need my mom.” She cried out over and over. As a mother I felt terrible for her. I just wanted to tell her that it would be alright. But we all knew that was a lie.
We were returned to North Korea.
The secret police demanded the women strip naked and they searched our genitals for anything we might have hidden, slapping and whipping us and calling us whores the entire time. My interrogator wanted me to confess to trying to defect to South Korea. I begged her to understand my situation but instead she grabbed my head and slammed it against a nail in the wall. I remember thinking as she took a fistful of my hair “Is this my fate? Is this how I’ll die? The tears mixed with the blood pouring out of the gash in my forehead.
I couldn’t let go of the thought of Hee-Mang growing up without a mom. I wanted to be a good mother, I wanted to give her everything she deserved. I knew I couldn’t die here.
Everyone in my group but me was sent to a political prison camp, even those two little boys. But because I refused to confess to trying to defect, I avoided that fate and was instead transferred to another prison where I was forced to work 18 hours a day in a gold mine to earn money for the regime.
They worked us so hard and fed us so little. But I had a daughter waiting for me. And now more than ever, I wanted her to live in freedom. Life in prison was so difficult that I considered killing myself many times. There is a saying in North Korea “Women are weak, but mothers are strong”. Being Hee-Mang’s mother gave me the strength to withstand the pain. For two years, I endured the back-breaking work hoping for the day I would reunite with Hee-Mang.
3 years after I was released I stood next to the Tumen again, staring north and dreaming of freedom. This time I had Hee-Mang with me. She was 4 years old now and I wanted her to have a happy, fulfilling life. I wanted her to see the world and learn about other cultures. There was nothing for her in North Korea except pain and misery. So I scooped her up from her bed and carried her out of the house.
I put her on my back, her head nestled on my shoulder, and waded into the river. I was almost to the middle of the river when her foot touched the water.
Hee-Mang woke up and whimpered “Oh it’s cold.” That’s all it took.
The border guards heard her and raced down to the water. I waded faster and faster with Hee-Mang’s little arms wrapped tightly around my neck. I lunged with each step trying desperately to get away. Then I felt a hand grab my hair. Hee-Mang started screaming as I tried to fight them off. But when they ripped her from me, I had no choice. I surrendered.
They dragged us back to shore and started kicking me and stomping on my head. And then they kicked my daughter. My precious, beautiful, Hee-Mang. An innocent 4-year old girl. She was sobbing in pain and her cries for mommy were muffled by the blood spilling out from her mouth.
I jumped on top of her to cover her little body from the soldiers’ boots. I pleaded with them to beat me instead. She didn’t know what was going on.
It wasn’t her fault. “It was me, I did this! Punish me, not her!” I screamed.
--
Last year I crossed the Tumen for the final time. I could see my breath as I shuffled across the ice on my hands and knees. I crawled up the other bank into China, bent back the barbed wire, and ran for the van that was waiting for me on the other side. From the van, I looked back at North Korea and wondered if I’d ever come back or see Hee-Mang again.
This time I connected with someone that knew a group helping North Korean refugees reach safety. The group turned out to be Liberty in North Korea and they helped me move quickly out of the border region and then we headed south. I couldn’t eat or sleep until we made it out of China because I was so scared of getting caught. Every time the bus stopped, I was certain that the police had found me again.
But soon I found myself crossing the border into Southeast Asia. When LiNK’s field staffer told me I was finally safe I was overwhelmed. I had endured so much to make it this far - hard labor, imprisonment, and torture. And even though I was overjoyed to make it to freedom, I was deeply saddened that Hee-Mang wasn’t with me.
I left her with my family because I couldn’t bear the thought of her getting caught again and sent to a political prison camp. I question that decision every day.
Today I owe it to my daughter to tell my story. Hee-Mang is like a lighthouse to me. She gives me light and a reason for why I need to keep living and working hard for freedom. I hold onto the dream that one day we will live together again.
Before I left last year I bought us matching watches. It’s just a cheap watch, but to me it has more value than any jewel. When I miss her, I wear it and I have hope that each minute that passes is one minute closer to the day I will see her again.
I wouldn’t be telling this story today without the support of people like you. Thank you for helping me escape and finally reach freedom. Your willingness to help North Koreans even though you do not know our names or see our faces, is unbelievable. Your generosity has changed my life and the lives of so many others.
But most of all, you give me hope that one day I will be able to return to the Tumen River and walk hand in hand with Hee-Mang.
And we will no longer have to be afraid. Because we will be together.
And we will be free.
Thank you.
