The European Union said President Donald Trump’s administration is shifting its approach to a landmark global agreement on climate change, an assertion which was quickly denied by the White House.

The U.S. signaled that it’s no longer seeking to withdraw from the pact and then renegotiate it, but rather wants to re-engage with the Paris Agreement from within, said EU’s climate chief Miguel Arias Canete. He spoke in an interview from Montreal, where the U.S., China, Canada and almost 30 other countries gathered to discuss the most-sweeping accord to date to protect the environment.

“Our position on the Paris agreement has not changed. @POTUS has been clear, US withdrawing unless we get pro-America terms,” White House Press Secretary Sarah Huckabee Sanders said on Twitter.

Announcing plans to quit the pact, Trump said in June that the agreement favored other countries at the expense of U.S. workers and amounted to a “massive redistribution” of U.S. wealth.

Trump’s administration last month began the formal process of exiting from the climate accord, drawing fire from allies and foes alike. EU climate commissioner Canete made the comments about a change of stance after meeting with Everett Eissenstat, deputy director of the National Economic Council and deputy assistant to the president for international economic affairs.

“Now we don’t see the messages that they are withdrawing from the Paris agreement radically,” Canete said, adding that the countries at Saturday’s meeting agreed not to seek a re-negotiation of the Paris deal.

Finalized in December 2015 after years of negotiations, the climate pact united more than 190 nations in a pledge to work toward limiting fossil-fuel emissions. Envoys will meet again in November to discuss how to implement the agreement. The message from the U.S. at Saturday’s gathering “at least pointed in the direction that they will participate constructively” in the talks, Canete said.

“They are willing to re-engage under the Paris agreement but they want to check some of the terms under which they agreed to participate previously,’’ he said. “We assume that means that the U.S. will revisit at some time the targets put forward by the previous administration.”

Canete is due to meet with the NEC director Gary Cohn on Monday in New York. “We expect the American administration will elaborate further on the message that they gave today in Montreal at a political level,’’ Canete said.
