The G7 summit ends without United States commitment on Paris agreement

"I will make my final decision on the Paris Accord next week!" he tweeted.

It was noted his attitude to climate change was one of the major hurdles during the summit in Sicily - the first time he has met his fellow G7 leaders as a group. The President teased his decision about the hotly debated topic in a tweet early Saturday morning Eastern time during the final leg of his first presidential trip overseas.

This is despite United States defence secretary James Mattis saying in an interview to air on Sunday that the president is now "wide open" on the issue.

The US leader, concluding his first overseas trip in office, later left for home without giving the customary close-of-summit news conference. In the statement, several countries signaled support for the Paris Climate Accord, which was approved by an overwhelming part of the worldwide community during the Obama administration.

Trump did not participate with his G7 counterparts in promising to back the 195-nation Paris climate accord, The Hill reported Monday.

North Atlantic Treaty Organisation countries do not pay the United States or North Atlantic Treaty Organisation directly.

The comments from Mattis, in an interview aired today, come after Trump tweeted yesterday that he would take a decision "next week" on whether to stick to or renege on the climate agreement.

"The entire discussion about climate was very hard, if not to say very dissatisfying", German Chancellor Angela Merkel told reporters.

French President Emmanuel Macron struck a more positive note, saying the talks had been useful.

As a candidate on December 1, 2015, Trump posted a video on Instagram - while the 2015 United Nations Climate Change Conference was taking place - in which he criticized then-President Obama for "worrying about global warming".

"He came here to learn", Cohn said at the summit. Italian Prime Minister Paolo Gentiloni said they were satisfied after the meeting but was open about disagreements with the United States: "We do not disguise this division".

There were mixed feelings over the results of the G7 summit. Secretary of State Rex Tillerson has also supported staying in the Paris agreement.

And what's more, some of Mr Trump's own country is likely to ignore his scepticism. "(.) It would be going tragically against the grain of history". Greenpeace regretted the outcome but held out hope that Trump might change tack. Trump may be willing to stay in the agreement, Cohn said, if the USA can scale back commitments made by President Barack Obama.

"Clean energy is not a partisan issue", said Nat Kreamer, CEO of Spruce, a company which provides homeowners with financing for solar systems.

The leaders acknowledged Trump's stance on trade and the communique includes a statement that the leaders will keep markets open, but "stand firm against all unfair trade practices".

Mr Trump barged past Montenegro's leader for prime photo real estate at North Atlantic Treaty Organisation, while France's new President Emmanuel Macron snubbed Mr Trump's embrace - the vigorous, vigorous handshake.

On NATO, US defense chief says: "If you want to take something out of it you've got to put something into it".
