Last week watchdog China Labor Watch published an investigation into Samsung's supply chain that found evidence of child labor at the Shinyang Electronics factory in Dongguan, China. The discovery contradicted Samsung's own self-audit, and now the Korean company has suspended business with the supplier after beginning a follow-up investigation. Samsung says Chinese authorities are also looking into the allegations.

In a statement, Samsung said it discovered that instances of "illegal hiring process" may have taken place at the Dongguan factory on June 29th, despite conducting audits at the location three times since 2013 and most recently on June 25th this year. "If the investigations conclude that the supplier indeed hired children illegally, Samsung will permanently halt business with the supplier in accordance with its zero tolerance policy on child labor," the company says, adding that it plans to "strengthen its hiring process" at both its production facilities and suppliers.
