Taiwan's Foxconn Technology Group has raised wages by up to 25% for its Chinese workers who assemble electronic gadgets for Apple and other global brands.
Foxconn said its Chinese workers now receive 1,800-2,500 yuan (£180-£250) per month following pay rises which took effect on February 1.
Foxconn employs about one million workers at several massive plants in China.
In 2010, a spate of worker suicides at an enormous Foxconn complex in the southern town of Shenzhen drew attention to the stress many young workers faced working in some factories.
Subsequently, Foxconn then raised its monthly wages from 900 yuan (£90) to up to 2,000 yuan (£200).
