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!
Foreign Media in North Korea - How Kpop is Challenging the Regime
Movies, TV shows, and music hold power. They’re a way for us to connect through common experiences, reckon with different sides of humanity, and revel in the beauty of being here at all. They transport us to another time and place- perhaps one of our imaginations- and most importantly, allow us to dream and imagine a limitless future.

In recent years, South Korean media and entertainment has gained international recognition. People like Hyun Bin and Son Yejin, the stars of popular Korean drama Crash Landing on You, have become household names, while Parasite swept the 2020 Academy Awards and music from K-pop groups like BTS are charting globally.
Meanwhile, just across the border, North Korea remains one of the most closed societies in the world. Yet even in the “hermit kingdom,” foreign media is accelerating empowerment of the people and change within the country!
Forced Isolation and the Regime’s Information Monopoly
The North Korean government has maintained power for decades through a system of imposed isolation, relentless indoctrination, and brutal repression. A complete monopoly on information and ideas within the country has been key- outside media threatens to challenge the legitimacy of their propaganda, and by extension, their control.
The 2014 United Nations Commission of Inquiry on Human Rights in North Korea reported an almost complete denial of the right to freedom of thought, conscience, and religion as well as of the rights to freedom of speech, opinion, expression, and association.

The regime employs a range of strategies to enforce information control:
- Restricting movement across borders and within the country
- Random house searches
- Severe punishment, including public executions, to deter foreign media consumption and sharing
- Sophisticated digital surveillance
- Jamming phone signals and locating users through signal triangulation
- Mobile OS file signature system that only permits government-approved apps and files
The Spread of Foreign Media
Despite this isolation and unparalleled internal restrictions, the North Korean people have been quietly changing their country from within, including through foreign media access. Through market activity and the movement of people and goods across the Chinese border, they have forced the gradual opening up of their society. Movies and music are smuggled into the country on USBs, SD and MicroSD cards, and small portable media players, offering illicit access to information from the outside world.
With lights off and windows shuttered, North Koreans will watch foreign media despite the risks. If all else fails, bribes are a way for people to reduce punishment if caught. Most North Korean police and government officials rely on bribes to survive, and some defectors complain that they are actually the biggest consumers of foreign media because they confiscate so much.

Information Technology in North Korea
Within North Korea, a broad range of information technologies are available, although they should be registered with authorities. Laptops and computers officially run on a government operating system, Red Star OS, while the North Korean intranet, Kwangmyong, is air-gapped from the internet and heavily surveilled. However, in practice, many North Koreans have non-networked devices used for games, editing software, watching videos, and to copy, delete and transfer media on removable devices.
Mobile phones are also common with approximately 6 million on the North Korean network, meaning roughly 1 in 4 people have one. These North Korean phones generally cannot make international calls and the operating system limits users to approved state media (programs have been developed to bypass this security). On the other hand, smuggled Chinese phones can be used in border regions on the Chinese network. These have been crucial for staying in touch with relatives who have escaped or defected, who often send back money and information from the outside world.

Radios are the only channel of foreign media and news available real-time across the country. While they should officially be registered and fixed to North Korean stations, it is relatively easy to tamper with radio sets to pick up foreign broadcasts. In border regions, some TVs can also pick up live programming from South Korea and China. Traditionally, TVs were connected to DVD players, but newer LCD televisions also have direct USB input ports.
How Foreign Media Changes Perceptions
Among foreign media, entertainment from South Korea is particularly attractive, produced in the same base language by people with the same ancestry. They contain glimpses of rich and free realities just across the border. In comparison, domestic North Korean media seems old-fashioned and disingenuous, designed to reinforce the regime’s ideologies.
As North Koreans learn more about life, freedom and prosperity in the outside world, and their own relative poverty, the regime’s ideology and control are eroded.

“At first you see the cars, apartment buildings, and markets and you think it must be a movie set. But the more you watch, there’s no way it can be just a set. If you watch one or two [movies] it always raises these doubts, and if you keep watching you know for sure. You realize how well South Koreans and other foreigners live.”
– Danbi, escaped North Korea in 2011
Empowered by foreign media, North Koreans are exploring their creativity and potential through everyday acts of resistance- using South Korean slang, copying fashion styles, and sharing pop culture references. In this culture war, Kim Jong-un has called for crackdowns on "unsavory, individualistic, anti-socialist behavior" among young people to restrict freedom of expression.
Foreign media also facilitates shared acts of resistance. People will swap USB devices with trusted friends and neighbors, increasing confidence in one another through a symmetrical transaction. Some people may also watch and discuss movies and shows together, increasing the media’s subversive influence and creating social networks.
The Regime’s Response
During the pandemic, we’ve seen unprecedented levels of isolation and restrictions, closing off the country more than ever before. To buttress control, Kim Jong Un has simultaneously increased crackdowns and punishments on foreign media consumption. In December 2020, the “anti-reactionary thought law” made watching foreign media punishable by 15 years in a political prison camp.
While the situation is harrowing, the government’s extreme response underscores the power of foreign media. The regime recognizes that social changes driven by North Korean people are a threat to their authority and control in the long term.
Accelerating Foreign Media Access and Change
Moving forward, increasing access to outside information is one of the most effective ways to help the North Korean people and bring forward change.
Information and technology support for North Korean people has historically been an under-utilized and under-invested strategy. LiNK Labs is our area of work focused on this opportunity- we’re developing technologies, networks, and content to empower North Korean people with access to information and ideas from the outside world.
