After Apple hinted at increasing the price of its products owing to tariffs on China, US President Donald Trump has once again asked the iPhone maker to shift manufacturing from Beijing to Washington. Apple has written a letter to the Trump administration, saying the proposed $200 billion tariffs on China-made products will make the Apple Watch, AirPods headphones, HomePod smart speaker, Macs and key computer parts more expensive.

"Apple prices may increase because of the massive Tariffs we may be imposing on China - but there is an easy solution where there would be ZERO tax, and indeed a tax incentive," Trump tweeted on Saturday. "Make your products in the United States instead of China. Start building new plants now. Exciting! MAGA." In January 2017, Trump said he spoke to Apple CEO Tim Cook over the phone and he promised to build "three big plants" in the US. But Cook never directly responded to that claim.
