Apple CEO Tim Cook attends the White House State Dinner with Lisa Jackson, Apple's VP of the Environment. Cook urged calm and called for more open trade after Trump announced he would impose tariffs on certain Chinese imports, and China retaliated with tariffs on us imports.
Also on the guest list were: IBM CEO Ginny Rometty; News Corp. and 21st Century Fox Co-Chairman Rupert Murdoch, FedEx CEO Fred Smith, Chef Guy Savoy, Chief Justice John Roberts, President Trump's daughter Ivanka and her husband Jared Kushner.
Tim Cook, Apple CEO, speaks at a economic summit a day before the China Development Forum in Beijing on March 24, 2018.
A trade war could place Apple in the Chinese government's cross-hairs.
Earlier in April, Trump imposed tariffs on more than 1,300 categories of products from China - including some televisions and batteries, but not smartphones - as part of his effort to crack down on Beijing firms believed to be stealing intellectual property from USA companies.
The escalation has prompted fears of an worldwide trade war, particularly in Silicon Valley, which sources and sells its products around the world.
It was not clear what Trump and Cook planned to discuss, and representatives for Apple did not immediately respond to a request for comment.
The Information Technology Industry Council, a lobbying group for companies like Apple, Google and Microsoft, previously has rebuffed Trump's tariffs as "entirely counterproductive" - and stressed the result would be higher prices on tech products that "penalize US consumers". Trump ultimately terminated the program anyway.
