French Foreign Minister Jean-Yves Le Drian said all parties must respect the nuclear deal, including the United States, which was part of the group that included Britain, China, France, Russia and Germany to negotiate the agreement.
The EU's top diplomat, Federica Mogherini, said the deal, denounced by Trump as the worst ever made, had in reality "made the world safer and prevented a potential nuclear arms race in the region".
BRUSSELS-The European Union hosts Thursday in Brussels a meeting with the Foreign Ministers of Iran, France, Germany and Britain to discuss developments in the 2015 nuclear agreement with Iran.
Iran has ratcheted up threats to end cooperation on curbing its suspect nuclear programs if the administration refuses to waive the sanctions, a move that would effectively pull Washington out of the multilateral deal that Britain, France, Germany, China and Russian Federation all agreed to with Tehran.
Zarif denied reports that the talks would focus on the recent protests in Iran that claimed 21 lives, saying such claims were "baseless and unfounded".
Iran says the missiles it has tested are not created to carry nuclear warheads and insists its nuclear programme is entirely peaceful.
Foreign ministry spokesman Bahram Ghasemi said that withdrawal by the United States would lead to an "appropriate and heavy response", adding that "the USA administration will definitely regret it".

Parekh said, "We are progressing towards stability and are well positioned to serve our clients in the new areas of demand". COO Pravin Rao said: "Increased adoption of our digital offerings and new services helped stabilize price realization".
Iranian Foreign Minister Javad Zarif said there was "strong consensus" on the deal but warned that Iran's continued compliance depended on that of the United States. "It is under continuous review and our participation can be cancelled by me as president at any time", Mr. Trump said.
But Bob Corker, head of the Senate Foreign Affairs Committee, said last week that while talks on Iran were continuing with the White House and its European partners, no new bill was imminent.
The next deadline for Trump to waive sanctions falls on Friday.
What does Mr Trump want to change?
Officials in the Trump administration have suggested that Trump plans to extend the waivers that lifted sanctions on Iran, but could seek new measures over issues such as human rights issues and missile programs.
Iran has insisted its nuclear program was exclusively peaceful in nature.
That requirement has caused increasing friction in the White House as senior national security officials and Secretary of State Rex Tillerson work to convince an increasingly frustrated Trump that he preserve a deal the president believes is flawed, sources said.
Critics of the deal in Congress have also proposed amending legislation to ensure that USA sanctions would "snap back" automatically if Iran carried out certain actions.
Three other Trump administration officials told CBS News there were a number of factors in play and cautioned that it was not at all certain that the president will heed the advice of his national security team to uphold the agreement.
