(Bloomberg) -- Apple Inc.’s next-generation iPhone 15 is beginning production in Tamil Nadu, in an effort to further narrow the gap between its India operations and main manufacturing base in China.

A Foxconn Technology Group plant in Sriperumbudur is preparing to deliver the newest devices only weeks after they start shipping from factories in China, as the company seeks to swiftly increase the volume of new iPhones coming from India, people familiar with the matter said.

The Cupertino, California-based firm is on a multiyear project to diversify its manufacturing away from China, de-risking the supply chain for its most important products as tensions between Washington and Beijing make trade less predictable. India, under Prime Minister Narendra Modi, has sought to build closer ties to the US and make itself a manufacturing hub.

Before the iPhone 14, Apple had only a sliver of its iPhone assembly in India, which lagged China output by six to nine months. That delay was drastically reduced last year, and Apple produced 7% of its iPhones in India at the end of March. The goal this year is to move closer to parity on shipment timing from India and China, though suppliers are not yet certain they will achieve it, the people said, asking not to be named as the information is not public.

“Apple’s increased production in India will lead to more of its supply chain moving to the country,” said Shilpi Jain, a senior analyst at Counterpoint Research. “While it’s still early days for Apple in India, I believe the government has a very clear ambition to move up the value chain in electronics manufacturing. And Apple’s push certainly helps.”

The scale of India production for the iPhone 15 will depend on the ready availability of components, which are largely imported, and the smooth ramp-up of production lines at the Foxconn factory outside Chennai.

The new iPhone, likely to be announced on Sept. 12, promises to be the biggest update to the device in three years. It will include major upgrades to the camera system across the range, and the Pro models will gain an improved 3-nanometer processor. The new family of handsets is critical to reviving flagging sales. Apple this month reported its third straight quarter of declining sales, weighed down by tepid consumer demand in key markets like the US, China and Europe.
