With the recall of the Chinese workforce, the effort to transfer technology built by Apple has been interrupted at Indian plants

The move comes as Foxconn and other Apple suppliers have been ramping up manufacturing in India as the iPhone maker seeks to reduce its reliance on Chinese manufacturing for its hardware. In May, Foxconn received Indian government approval to build a $435 million semiconductor plant in the country.

Foxconn Technology Group has asked hundreds of Chinese engineers and technicians to return home from its iPhone factories in India, dealing a blow to Apple Inc.’s manufacturing push in the South Asian country.
