"Looking forward to dinner tonight with Tim Cook of Apple. He is investing big dollars in USA," said Trump, who is on vacation at his golf club in Bedminster, New Jersey.
Cook said in a conference call with investors last week that Apple was looking at whether Trump's tariffs in a trade war with China would hit the company on the purchases it must make.
The New York Times reported in June that Trump told Cook that the US government would not levy tariffs on Apple iPhones assembled in China.
The newspaper reported that Cook travelled to the White House in May to warn Trump of the potentially adverse effects of Trump's trade policies on Apple in China, but did not specify precisely when Trump made the commitment to Cook.
Apple this month became the first $1 trillion (roughly Rs. 69 lakh crores) publicly listed US company.
