"We have explained to [President] Trump in Taormina it wouldn't be good for the world and the USA if the USA took a step back from the world stage because vacuum will be replaced and the Chinese are pushing to take over the lead", he said.

In signing onto the accord, countries pledged to reduce greenhouse gas emissions, but were given wide leeway in how much they planned to reduce them by.

At present, U.S. is the second-largest carbon polluter of the world.

China overtook the U.S. as the world's biggest emitter of greenhouse gases in 2007.

"China and the European Union. will implement the agreement", a senior European Union official told reporters, on condition of anonymity. That promise helped rally supporters sharing his skepticism of global efforts to police U.S. carbon emissions.

The possibility Mr Trump - who has previously described climate change as a hoax by the Chinese - could pull out within days was labelled disastrous and as putting the United States on "the wrong side of history" in some quarters.
