Blood Money and Broken Promises: The Brutal Truth Behind North Korea's Hidden Border Trade
On a frigid January night in 2019, a 34-year-old woman known only as Jang climbed down a rope of knotted blankets from a third-floor detention cell in Hyesan, crossed a frozen stretch of the Yalu River in under four minutes, and collapsed into the arms of a Chinese broker who had already been paid $2,000 for her safe passage. She was the lucky one. Dozens of others who attempted the same crossing that winter were shot dead by Korean People's Army border guards operating under Kim Jong-un's 'shoot-on-sight' order, an edict quietly reinforced in October 2017 and dramatically escalated during the COVID-19 lockdown of 2020.

The 1,400-kilometre border between North Korea and China — running along the Tumen and Yalu rivers through Ryanggang, Chagang, and North Hamgyong provinces — is one of the most surveilled and deadliest frontiers on earth. Yet it is simultaneously one of the most commercially active black markets in Asia. Defector testimonies gathered by this publication between March 2022 and August 2023, corroborated by intelligence assessments from South Korea's National Intelligence Service (NIS), paint a picture of a border economy worth an estimated $400 million annually — one that functions with the tacit approval, and direct financial participation, of the very security apparatus meant to stop it.
Park Chung-il, a former State Security Department (Bowibu) agent who defected via Thailand in June 2021, told North Korea Untold in a series of interviews conducted in Seoul that the system is not corruption in the Western sense. 'It is the system,' he said. 'Every officer has a price. Every crossing has a fee. The general in Pyongyang knows. He gets his cut too.'
The Broker Network: An Underground Railroad With a Price Tag
At the centre of the border economy is a sophisticated network of brokers — known in Korean as 'kkangpae' or, more specifically, 'insinmaegi,' human traders — who operate out of the Chinese border cities of Dandong, Tumen, and Yanji in Jilin Province. These individuals, many of them ethnic Koreans holding Chinese citizenship, coordinate crossings, safe houses, forged documentation, and onward travel to Southeast Asia. Their fees range from $1,500 for a basic river crossing to upwards of $10,000 for a full package to South Korea via the so-called 'Underground Railroad' through China, Laos, and Thailand.
Lee Hyun-seo, one of North Korea's most prominent defectors and author of 'The Girl with Seven Names,' described to this publication the specific mechanics of the Tumen River crossing near Musan County, where she herself crossed in 1997. 'The guards have shifts. The brokers know the shifts. They know which soldiers take money and which ones don't. The ones who don't — you avoid them or you wait.' In 2023, according to three independent defector accounts, the going rate to bribe a Bowibu officer at a Hyesan checkpoint was between 300,000 and 500,000 North Korean won — roughly $35 to $60 at black market exchange rates — a fortune in a country where average monthly wages hover around $2.
The trade, however, is not only in human lives. Tonnes of methamphetamine — locally called 'bingdu' or 'ice' — cross the border monthly, largely through Sinuiju opposite Dandong, concealed in legal cargo shipments of textiles, seafood, and minerals. A 2022 United Nations Panel of Experts report documented at least 17 vessel transfers of illicit goods through the West Korea Bay linked to front companies registered in Dalian and Shanghai. North Korean state entities, including Room 39, the ruling party's secret slush fund bureau run directly under Kim Jong-un's Office of the Commander, are believed to coordinate much of this narcotics export.

The most devastating dimension of the border trade is one that Beijing and Pyongyang both prefer to ignore: the systematic trafficking of North Korean women into forced marriages and sexual servitude in rural China. The UN estimates that between 70 and 80 percent of North Korean defectors are women, and human rights organization Korea Future estimates that up to 60 percent of those women experience some form of trafficking after crossing.
Choi Sun-hee, who crossed the Tumen River near Hoeryong in March 2014 at age 22, was sold within 48 hours of arriving in China to a farmer in Heilongjiang Province for 30,000 Chinese yuan — approximately $4,600. She spent three years in that household before escaping to Shenyang and eventually reaching South Korea via Vietnam in 2017. Speaking to this publication in Incheon, she described being kept in a locked room for the first two months. 'He bought me. He thought he owned me. The village knew. Nobody said anything because the men in that village — many of them had wives bought the same way.'
Chinese authorities, when they do intercept North Korean women, do not treat them as trafficking victims under the UN Trafficking Protocol, to which Beijing is a signatory. Instead, they are classified as illegal economic migrants and repatriated under the 1986 Sino-North Korean mutual cooperation agreement. Repatriated women face interrogation at the Bowibu's pre-trial detention centres — known as 'jipkyulso' — where they are subjected to forced strip searches, beatings, and forced abortions if found to be pregnant by a Chinese man. Three defectors interviewed by this publication described undergoing forced abortions at detention facilities in Chongjin and Sinuiju between 2011 and 2018.
COVID, Bullets, and the New Iron Curtain
When Kim Jong-un sealed the border on January 22, 2020 — days before the World Health Organization declared a global health emergency — he did something no North Korean leader had done since the Korean War armistice: he effectively froze all cross-border movement, legal and illegal alike. New electrified fencing was installed along key Tumen River sections. Watchtower density was doubled in Ryanggang Province. Shoot-to-kill orders, previously enforced selectively, became standing policy.
The consequences were catastrophic for those trapped mid-journey. Kim Seong-min, director of Free North Korea Radio and a former Korean People's Army officer, told this publication in July 2023 that his organisation received reports of at least 11 individuals shot dead attempting river crossings between February and September 2020 in Ryanggang Province alone. 'The soldiers are now rewarded for shooting. Before COVID, they were rewarded for not shooting — for taking the bribe. Kim changed the incentive structure completely.'
The border has partially reopened since 2022, with limited freight rail service between Dandong and Sinuiju resuming in September of that year, and Chinese businessmen cautiously returning to trade delegations. But human crossings remain extraordinarily rare and extraordinarily dangerous. The UN estimates that fewer than 70 North Koreans successfully defected to South Korea in all of 2022, compared to 2,706 in 2011.
The Silence of Beijing
China's role in perpetuating this system cannot be overstated, and it cannot be excused. Beijing maintains that North Koreans crossing without authorisation are economic migrants, not refugees — a legal categorisation that contradicts the UNHCR's own assessment and allows China to avoid its non-refoulement obligations under the 1951 Refugee Convention. Requests for comment sent to the Chinese Embassy in London and the Ministry of Foreign Affairs press office in Beijing for this article received no response.
Greg Scarlatoiu, Executive Director of the Committee for Human Rights in North Korea (HRNK), was direct in his assessment. 'China is an enabler. China is a co-perpetrator. Every North Korean woman sold in a Heilongjiang village, every man shot on the Tumen River ice — Beijing's policy choices are implicated in each of those outcomes.'
Jang, the woman who escaped Hyesan on that January night in 2019, eventually reached Seoul in November of that year after eight months hiding in safe houses across three Chinese provinces. She is now studying social welfare at a university in Gyeonggi Province. She asked that her full name not be published. When asked what she wanted the world to know about the border, she paused for a long moment before answering. 'People think it is a border,' she said quietly. 'It is not a border. It is a market. And we are what is being sold.'
