Samsung Electronics said 59 suppliers failed to provide adequate safety equipment for workers as the world's largest smartphone maker struggles to improve labour standards at plants in China.
A majority of Samsung's suppliers do not comply with China's legally permitted overtime hours while no instances of child labour were found, the Suwon, South Korea-based company said in its annual sustainability report published on its website Monday.
Additional training is being provided to suppliers to prevent injuries to workers and improve standards.
Samsung and Apple, are among companies auditing their supply chain to improve worker conditions, avoid use of so-called conflict minerals and reduce the impact on the environment. The Galaxy smartphone maker came under fire in 2012 for conditions at supplier plants and promised to end hiring discrimination and ensure adequate safety equipment and training by the end of that year.
"Labour costs are rising in China so it's becoming more difficult for companies operating there," said Lee Moon Hyung, a Beijing-based director at the Korea Institute for Industrial Economics & Trade. "They also have to meet their social responsibility standards. That's not optional."
