Already, Trump has shaken up the schedule, calling at the last minute for a special meeting Sunday morning to discuss the global economy. Senior administration officials said he will contrast U.S. growth with Europe’s economic doldrums and press his pro-jobs and “fair” trade messages.

Senior administration officials told reporters in a briefing call Thursday that Trump planned to “frankly” discuss sticking points among G-7 nations including trade, a digital services tax and NATO spending obligations.

It is unclear how receptive the others will be to whatever thoughts Trump might offer as to how they should shift their own economic approaches. Many world leaders blame Trump’s trade war with China and his threats against Europe and Japan for a major contraction in investment and spending, and are frustrated with what they see as attempts to use weaknesses elsewhere to demand changes he thinks will benefit U.S. companies.
