President Donald Trump met with Apple Inc. Chief Executive Officer Tim Cook on Wednesday to discuss trade issues as the technology industry grapples with a U.S. spat over import tariffs with China, a manufacturing hub for the iPhone maker and other companies.

Trump, in a morning tweet, said he was looking forward to seeing Cook. "We will be talking about many things, including how the U.S. has been treated unfairly for many years, by many countries, on trade," he wrote.

White House spokeswoman Sarah Sanders said on Wednesday afternoon that the meeting was underway, and that "the primary focus" was to discuss trade. A White House official said later the meeting had concluded, but there was no word yet on details of the discussions.
