"What the president means by free and open is, we will treat you the way you treat us, meaning if you don't have barriers to trade or you don't have tariffs, we won't have tariffs", he said, quoted by Reuters. The agreement was entered into under the Obama Administration.
Six of the seven G7 nations agreed to stick with their commitment to implement the 2015 Paris Agreement aimed at slowing global warming, but Mr Trump said he needed more time to decide if the USA would abandon the accord.
The summit of Group of Seven wealthy nations pitted Trump against the leaders of Germany, France, Britain, Italy, Canada and Japan on several issues, with European diplomats frustrated at having to revisit questions they hoped were long settled.
But US partners hit deadlock in their attempt to persuade Trump to keep the world's biggest economy inside the framework of the 2015 Paris Agreement on curbing carbon emissions to reduce global warming. This choice should not be hard: uphold the Paris Agreement to take climate action, grow the economy, and protect US communities or break our commitments to turn his back on economic success, American leadership, and the future of every family in our nation.
German Chancellor Angela Merkel told reporters on the Italian island "the entire discussion about climate was very hard, if not to say very unsatisfying", while Italian Prime Minister Paolo Gentiloni, said: "I hope they [the US] decide in the right way".
"There is one open question, which is the USA position on the Paris climate accords", Italian Prime Minister Paolo Gentiloni said at the Group of Seven summit in Italy on Friday. Macron said he told Trump it is "indispensable for the reputation of the United States and the interest of the Americans themselves that the United States remain committed" to the Paris climate agreement. Ironically, even Trump's Mar-a-Lago resort could be submerged in 30 years time if climate change goes unaddressed.
At the G7 summit in Italy, Trump was the odd one out on climate issues.
German Chancellor Angela Merkel, who also crossed swords with Trump on free trade at the G7, complained that the USA president was keeping his colleagues in the dark.
Lawyers and public relations experts are being recruited, the Associated Press reported Sunday, as new revelations surface about Moscow's interference and possible improper dealings with the Trump campaign and associates. He hasn't made an official decision yet, but if the president decides to pull out of the Paris Agreement that Obama signed in 2016, it could make things hard for Canada - although it won't stop climate initiatives from going forward, according to a former Canadian diplomat.
