Donald Trump said Thursday that he told Apple CEO Tim Cook he opposes the company building products in India, according to CNBC. Trump referenced Apple’s February pledge to invest $500 billion in the U.S. and expressed frustration over the company’s continued shift away from China by building its supply chain in India. Apple aims to make 25% of its iPhones in India within a few years, as it seeks to reduce its reliance on Chinese production, where about 90% of iPhones are currently assembled. Experts say relocating iPhone production to the U.S. is highly unlikely due to cost concerns. Estimates suggest a U.S.-made iPhone would range from $1,500 to $3,500.
