To circumvent the high tariffs imposed by President Trump on China, Apple and several other major technology companies in the world have begun moving their manufacturing to India, which has lower tariffs. Apple may be the most affected because the majority of its products are still manufactured in China and therefore they have invested several billion in India this year. But Tim Cook's efforts may be challenged because Foxconn workers in India have been called back to China.
Apple does not have its own factories and relies on Foxconn and Luxshare to produce their products. With key workers also being called back to China, the process of moving manufacturing to India is now slightly affected. According to a Bloomberg report, up to 300 employees have been asked to return to China without any reason being given.
It is likely that China's efforts to prevent the overseas relocation process are being carried out. The called-back employees will not cause quality issues for Apple products manufactured in India. On the contrary, it will reduce the efficiency of the manufacturing process as Apple is ramping up production before the iPhone 17 series is launched next September.
