DHAKA: Tens of thousands of workers were on strike Wednesday at a factory in southern China which makes shoes for Nike and Adidas.

Rights groups and a worker said, reports The Straits Times.

More than 30,000 staff at the Yue Yuen Industrial (Holdings) factory in Dongguan city have been striking for several days in protest at unpaid social insurance payments, said United States-based China Labour Watch, adding that police had beaten and detained several protesters.

China is facing labour unrest as its economic growth slows and as factories in its southern manufacturing heartland report a shortage of workers, prompting rising demands from staff.

Yue Yuen says on its website that it produces shoes for foreign brands including Nike, Adidas, Puma and New Balance.
