Probe finds teenage slavery in Vietnam mines 11:11 p.m. Aug 06, 1997 Eastern By Adrian Edwards HANOI, Aug 7 (Reuter) - An investigation into child labour in northern Vietnam has uncovered evidence of teenage children working in appalling conditions in gold mines, a state daily reported on Thursday. A candid article in the official Vietnam News said an enquiry by police and local authorities in Bac Can province, some 150 km (90 miles) north of Hanoi, had found 82 children being used as cheap labour in 30 mines. The newspaper said teenagers aged between 13 and 17 were working in dangerous and filthy conditions, each hauling as much as four tonnes of rubble out of the mines every day. ``Many of the children were coughing blood due to the arduous work, and were locked up at night by mine owners, who feared that their cheap labour force would escape,'' the report said. It said one of the children, 15-year-old Nguyen Van Nam, had to work as much as 14 hours per day, but had not been paid for six months and was forced to forfeit meal breaks if he moved fewer than 270 15-kilogram (33-pound) baskets per day. Child labour exploitation is a complex problem in Vietnam. Its extent is difficult to assess because of a common practise of children helping their parents by working at home or in the fields. The government estimates around 29,000 children below the age of 15 are victims of exploitative labour. But a U.N. Children's Fund (UNICEF) official warned earlier this week that the figure was deceptive as most children at work in Vietnam were employed in the difficult to monitor informal sector. Rima Salah, of UNICEF's Hanoi office said there was also evidence that the problem was increasing. ``There is evidence of children exploited in gold mines, children working as domestic servants at a very young age or children working up to 14 hours a day in hazardous conditions for a meagre salary or no payment,'' she said in a statement. Vietnam News said the mine owners in Bac Can had been made to return the children to their families, but added that ``...many mine owners escaped into the forest, taking their child-workers with them.'' It said 68 of the children had been reunited with their parents and gold mine owners made to give back pay totalling some $1,025. The case is the second to emerge in recent months. In June a raid by security forces guards on an illegal gold mine close to the border with Laos in central Vietnam resulted in 15 teenage boys being rescued. The boys had worked in similar conditions. A UNICEF official, Damien Personnaz, applauded Vietnam's normally tightly-controlled domestic media for having reported both that issue, and the latest case with candour. ``If this story is really true then this is not about child labour. This is about slavery,'' he said on Thursday.
