Apple will reportedly begin assembling its top-end iPhones in India through the local unit of Foxconn as early as 2019.

Apple's partner will be assembling the most expensive models, such as devices in the flagship iPhone X family, Reuters reports. The work will take place at Foxconn’s plant in Sriperumbudur town in the southern state of Tamil Nadu, said the report.

Foxconn already makes phones for Xiaomi in India.

The Hindu newspaper reported on Dec. 24 that a Foxconn plant would begin manufacturing various models of the iPhone.

Foxconn said it did not comment on matters related to current or potential customers, or any of their products.

Until now, Apple has only assembled the lower-cost SE and 6S models in India through Wistron Corp’s local unit in the Bengaluru technology hub.

Foxconn, the world’s biggest electronics contract manufacturer, is also considering setting up a factory in Vietnam, Vietnamese state media reported this month.

The Chinese company has previously admitted the China-U.S. trade spat was its biggest challenge and that its senior executives were making plans to counter the impact.
