Last month, reports emerged that North Koreans working in China had rioted, after finding out they would not be paid, and that their wages had instead been put towards building weapons for Pyongyang. Instances of North Koreans protesting are virtually unheard of, as the state exercises near total control over its citizens, and public dissent can result in execution. The reported riots, though unconfirmed, have sparked concern for the wellbeing of the tens of thousands of North Koreans working overseas, earning money for the cash-starved regime.
The BBC has spoken to a former North Korean worker in China who claimed those working in some poorly performing companies had their wages withheld.
