In his meeting with Modi, Cook disclosed that Apple expected its Indian operations to be run completely from renewable energy within the next six months, according to a person familiar with the discussion.

Cook reiterated that Apple had generated 740,000 jobs in India through its so-called “app economy” and Indian developers had created nearly 100,000 apps for the App Store, the person said.

Modi talked with Cook and other U.S. corporate leaders ahead of a meeting with President Donald Trump on Monday. Apple, working with contract manufacturer Winstron, began assembling the iPhone SE in Bengaluru last month. Indian authorities have offered Apple tax concessions for the work with the requirement that more local components be used over time. The company is looking to India after sales in the greater China region, once a major factor in Apple’s rise, fell 14% year over year to $10.7 billion in the most recent quarter.
