Trump and his top climate and economic aids will kick-off discussions in earnest on Tuesday in the U.S., a senior administration official said, adding that "they are meeting tomorrow at 1.30 pm".
The announcement pushed back a decision that has sweeping implications for the fate of global efforts to fight climate change - and has drawn intense interest from the worldwide community, corporate lobbyists and environmental organizations.
However, during his campaign, Trump promised to "cancel" us participation in the agreement.
Before taking office, President Donald Trump pledged to cancel a deal signed by almost 200 countries in Paris in 2015, which aims to limit rising temperatures by phasing out use of fossil fuels.
Officials had already postponed the meeting once before, citing scheduling conflicts. Officials like Secretary of State Rex Tillerson and Trump's daughter Ivanka Trump want to stay in the pact, while Environmental Protection Agency head Scott Pruitt and strategist Stephen Bannon want to leave.
Trump vowed during his presidential campaign to "cancel" U.S. participation in the accord, which obliges countries to slash their greenhouse gas emissions to keep global temperatures from rising to catastrophic levels.
But the negotiations risk being hamstrung over fears that the world's number two carbon polluter will pull out and throw the pact into disarray.
But those views have been tempered by Trump's daughter, Ivanka, who has insisted aides provide her father with the full picture of what a withdrawal could mean for U.S., according to the people familiar with the talks.

The process for the United States to decide whether they can or should withdraw from the agreement is complex, though the Paris Agreement was not ratified through Congress. It therefore does not have the force of a binding treaty, and the United States could potentially withdraw from the deal without legal penalty.
Several former Obama administration officials on Monday called on the Trump administration to recognize that the Paris agreement is not overly constraining and that even with their pro-fossil fuel policies, they can live with it. Emmanuel Macron, who won election as France's new president on Sunday, said his country would continue the climate fight.
Bannon and Pruitt are said to be among those arguing for a tough line, rejecting global agreements they believe tie the hands of United States industry.
But her stance on the Paris accord and her influence inside the cut-throat world of White House politics are unclear. "So there is room for a new US administration to chart its own path as well".
He did not, however, make any direct criticisms of the Trump administration's policies.
Spicer's announcement came the same day that a team of top administration officials postponed deliberations on whether to recommend that the US stay in the pact or exit it, which Trump promised to do during last year's presidential campaign.
"I would rather wait until a decision has been taken", she said.
Another possible option for Trump, according to officials, is to remain within the agreement, but rework USA emissions targets.
