"After arriving home, we checked their conditions, and their temperature had reached 40C, and their heartbeat was abnormal and their pulses abnormally weak," Tith quoted one of the wives as saying. "So we tried to save them by injecting medicine and serum to weaken the intoxication, but an hour later, they had a heart attack and died."
When the Phnom Penh Post's reporters visited the clinic, they were told to leave by four North Korean men. "We don't want any interviews with journalists," one of them said, according to the report.
This is the latest episode in a recent spate of news involving North Korean doctors abroad. Three North Korean doctors were killed - one of them beheaded - in northeastern Nigeria in 2013, apparently by Boko Haram, the Islamist extremist group. Then there was a report in May last year that a North Korean doctor and his wife had been kidnapped in Libya by Isis (Islamic State) militants.
In Cambodia, North Korean doctors are reported to be working at medical clinics in Phnom Penh and Siem Reap, near the famed Angkor Wat site. They are part of a burgeoning number of North Koreans working abroad.
With few legal ways to make money in the outside world, Kim's regime has dramatically stepped up labour exports. From textile factories in China and logging camps in Russia to construction sites in the Middle East and mines in southeast Asia, North Koreans are earning money both for themselves and the regime. They typically get to keep one-third of what they earn - far more than what they could make at home.
