President Donald Trump tweeted on Friday that his administration will not grant Apple any tariff waivers for parts for its new Mac Pro that are made in China.
"Make them in the USA, no Tariffs!" the president said.
Trump appeared to be responding to tariff exemption requests the Cupertino-based company filed with the Office of U.S. Trade Representative (USTR) on July 18. Apple's requests were first reported by Bloomberg.
U.S. and Chinese officials are due to meet next week in a possible bid to revive trade talks and end a year-long dispute that has rattled global markets and disrupted supply chains.
