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.

Diplomats worked late into the night to try to agree the wording with the United States on global trade.

US President Donald Trump has clashed with world leaders, including Washington allies, over climate change and trade at what European Union officials call the most challenging meeting of the G7 in years.

Trump's spokesman Sean Spicer said Trump had "tremendous respect" for Germany and had only complained about unfair trade practices in the meeting.

"We are going to continue to fight for what we believe is right, which is free, open and fair trade, which the president has been very clear on what that means", Cohn said.

He also predicted "fairly robust" talks on whether Trump should honor a USA commitment to cut greenhouse gas emissions under the 2015 Paris Agreement.

The G-7 summit is the final stop on Trump's first trip overseas as president.

Once his first foreign trip draws to a close on Saturday, President Trump will return to the U.S. where his approval ratings are low and he is coming under increasing pressure over alleged Russian meddling in November's election.

Diplomats worked through the night trying to bridge the gap between the new USA administration and its allies Britain, Canada, France, Germany, Italy and Japan on a number of barbed issues, including trade, the environment and Russian Federation.

Gary Cohn, Trump's economic advisor, said the president had told his colleagues that he regarded the environment as important.

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.

ABC News, meanwhile, chose to focus on the President's "awkward body language moments" - including pushing the Montenegrin prime minister out the way.

"The surplus is also a sign of the good quality of German goods", she said. "He came here to learn; he came here to get smarter".

"Several points of this declaration refer to the strengthening of cooperation between the seven biggest economies in the western, free world", he said.
