Samsung has acknowledged poor working conditions at its factories in China after a labour group said investigators found widespread abuses.
An official at the South Korean company said it will start re-evaluating its labour practices in China.
The official said new product launches and production lines have led to long hours of work.
The company was responding to China Labour Watch's investigation of six Samsung-owned plants and two suppliers in China.
The watchdog said it found forced and excessive overtime, exhausting working conditions that require most employees to work standing, and other labour abuses at the eight plants.Reuse content
