Apple’s main supplier, Foxconn, is reportedly doubling wages for its employees. This follows a series of investigations that took place as a result of accusations about mistreatment of workers in the Chinese factories.

Want China Times reports that the minimum monthly salary for workers at Foxconn’s factories in mainland China will double by the end of 2013.

According to the report, Foxconn CEO Terry Gou had previously announced that the company’s salaries would rise above minimum wage in Taiwan by the end of 2012, but he has now decided that the monthly salaries should be doubled to 4,400 yuan (£443) by the end of next year, almost five times the wage given to factory employees in 2010.

Earlier this year, journalist Rob Schmitz became the second journalist to be granted access to Apple production lines in Chinese Foxconn factories, after the revelation that Mike Daisey, an author an actor who accused Apple of ill-treating its factory workers, had fabricated some of his reports.

Yesterday, rare footage from the iPhone production line in a Chinese Foxconn factory was revealed.
