Samsung Electronics Co Ltd on Thursday said it is investigating an allegation that a supplier in southern China used child labor. U.S. activist group China Labor Watch on Thursday released a report alleging that Dongguan Shinyang Electronic Co Ltd, a supplier of mobile phone covers and parts, hired child labor for its assembly lines. We are urgently looking into the latest allegations and will take appropriate measures in accordance with our policies to prevent any cases of child labor in our suppliers, Samsung said an emailed statement. The claim from the New York-based watchdog comes after Samsung said in an annual sustainability report on June 30 that a third-party audit of 100 suppliers in China found no instances of child labor.
