Now, with many of Russia’s men either killed or tied up fighting – or having fled the country – South Korean intelligence officials have told the BBC that Moscow is increasingly relying on North Korean labourers.We interviewed six North Korean workers who have fled Russia since the start of the war, along with government officials, researchers and those helping to rescue the labourers.They detailed how the men are subjected to “abysmal” working conditions, and how the North Korean authorities are tightening their control over the workers to stop them escaping.One of the workers, Jin, told the BBC that when he landed in Russia’s Far East, he was chaperoned from the airport to a construction site by a North Korean security agent, who ordered him not to talk to anyone or look at anything. “The outside world is our enemy,” the agent told him. He was put straight to work building high-rise apartment blocks for more than 18 hours a day, he said.All six workers we spoke to described the same punishing workdays – waking at 6am and being forced to build high-rise apartments until 2am the next morning, with just two days off a year. We have changed their names to protect them.Getty Images”Waking up was terrifying, realising you had to repeat the same day over again,” said another construction worker, Tae, who managed to escape Russia last year. Tae recalled how his hands would seize up in the morning, unable to open, paralysed from the previous day’s work.”Some people would leave their post to sleep in the day, or fall asleep standing up, but the supervisors would find them and beat them. It was truly like we were dying,” said another of the workers, Chan.”The conditions are truly abysmal,” said Kang Dong-wan, a professor at South Korea’s Dong-A University who has travelled to Russia multiple times to interview North Korean labourers. “The workers are exposed to very dangerous situations. At night the lights are turned out and they work in the dark, with little safety equipment.”The escapees told us that the workers are confined to their construction sites day and night, where they are watched by agents from North Korea’s state security department. They sleep in dirty, overcrowded shipping containers, infested with bugs, or on the floor of unfinished apartment blocks, with tarps pulled over the door frames to try to keep out the cold.One labourer, Nam, said he once fell four metres off his building site and “smashed up” his face, leaving him unable to work. Even then his supervisors would not let him leave the site to visit a hospital.In the past, tens of thousands of North Koreans worked in Russia earning millions of pounds a year for the North Korean leader, Kim Jong Un, and his cash-strapped regime. Then in 2019, the UN banned countries from using these workers in an attempt to cut off Kim’s funds and stop him building nuclear weapons, meaning most were sent home.But last year more than 10,000 labourers were sent to Russia, according to a South Korean intelligence official speaking to the BBC on the condition of anonymity. They told us that even more were expected to arrive this year, with Pyongyang possibly dispatching more than 50,000 workers in total.The sudden influx means North Korean workers are now “everywhere in Russia,” the official added. While most are working on large-scale construction projects, others have been assigned to clot …
