United States officials had signalled beforehand that Trump, who dismissed climate change as a "hoax" during his campaign, would not take a decision on the climate deal in Taormina, the cliff-top town overlooking the Mediterranean where G7 leaders met. "It will be solved, you can bet on that".
But in contrast to the collaborative and at times even playful demeanor leaders would assume during the eight years President Barack Obama was in office, Trump's emergence so far on the diplomatic circuit has shown his willingness to use the meetings to confront world leaders and openly express his grievances.
The leaders of the United States, Canada, Britain, France, Germany, Italy and Japan - countries collectively known as the Group of Seven (G7) - are meeting on Friday for a two-day summit in the resort town of Taormina, Italy.

Brigitte Macron and Melania Trump are both cutting elegant figures at events for spouses on the sidelines of the G-7 summit.
Pope Francis, who has framed climate change as an urgent moral crisis and blamed global warming on an unfair, fossil fuel-based industrial model that harms the poor, also appeared to be sending a message to Trump during their meeting.
Migration plus nuclear threats from North Korea will be also on the agenda.
Other leaders, including German Chancellor Angela Merkel and new French President Emmanuel Macron, had hoped to sway the president at his first major worldwide summit.
The clashes dominated conversations in and around the summit after the first day wrapped up Friday, with Italian Prime Minister Paolo Gentiloni, British Prime Minister Theresa May and German Chancellor Angela Merkel all singling out, with varying degrees of intensity, the US for getting in the way.
