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.

Apple's largest iPhone producer has reportedly ordered hundreds of its India-based Chinese workers to return to their native China but for unspecified reasons.

Apple's strategic push into the Indian market appears to have encountered a significant roadblock due to Foxconn's move to send Chinese engineers home from India operations, raising questions about the pace and ease of Apple expansion plans in the subcontinent.
