According to a statement: "There has been no change" in the US position "unless we can re-enter on terms that are more favourable to our country".
Officials who met a White House representative yesterday said afterwards the US would either stay in the 2015 accord or change its approach.
But President Donald Trump said in June he wanted a new "fair" deal for the US.
He added it was important a new deal would not disadvantage US businesses, but opponents say withdrawing from the accord is an abdication of US leadership on a key global challenge.
The Paris agreement commits the US and 187 other countries to keeping rising global temperatures "well below" 2C above pre-industrial levels and "endeavour to limit" them even more, to 1.5C.
Speaking in the White House Rose Garden, he characterised the Paris agreement as a deal that aimed to hobble, disadvantage and impoverish the US.
He claimed the agreement would cost the US 6.5 million jobs and $3tn in lost GDP - while rival economies like China and India were treated more favourably.

"In order to fulfil my solemn duty to protect America and its citizens, the United States will withdraw from the Paris climate accord... but begin negotiations to re-enter either the Paris accord or a really entirely new transaction on terms that are fair to the United States," he said.
During his visit to France in July, however, Mr Trump hinted that the US could shift its position on the deal - but did not elaborate.
"Something could happen with respect to the Paris accord... We'll see what happens."
On Saturday, the Wall Street Journal quoted European Commissioner for Climate Action and Energy Miguel Arias Canete as saying that Trump administration officials said the US would not pull out of the agreement, and were offering to re-engage in the international deal to fight climate change.
The WSJ said the shift in the position came at a meeting of environment ministers from about 30 countries at a gathering in Montreal, Canada.
