The European Union and foreign ministers of France, Germany and the U.K., expressed "great concern" on Thursday over Iran's announcement that it was partially scaling back compliance with the nuclear deal and said it remains committed to it.
"We remain fully committed to the preservation and full implementation of the Joint Comprehensive Plan of Action, a key achievement of the global nuclear non-proliferation architecture, which is in the security interest of all," the joint statement said.

In response, U.S. President Donald Trump imposed new sanctions targeting Iran’s s revenue from export of industrial metals and threatened further action unless Tehran "fundamentally" changed its behavior.
While expressing concern regarding Iran's commitments to the deal, the countries urged the Islamic Republic to continue implementing its commitments under the JCPoA and refrain from escalatory steps.
"We reject any ultimatums and we will assess Iran’s compliance on the basis of Iran’s performance regarding its nuclear-related commitments under the JCPoA and the NPT (Treaty on the Non-Proliferation of Nuclear Weapons). In this respect, we recall the key role of IAEA (International Atomic Energy Agency) monitoring and verification of the implementation by Iran of its nuclear-related commitments," the statement further reads.

The statement also expressed "regret" regarding the U.S. imposition of sanctions following their withdrawal from the deal.
In a nationally televised speech, Rohani said Wednesday that after 60 days, Iran will scale back more compliance with the deal, and will increase their uranium enrichment.
He also warned of a "firm response" if the nuclear case is once again referred to the UN Security Council, and that Tehran is ready for nuclear negotiations. The five world leaders were also told that Tehran will no longer sell its enriched uranium and heavy water to other countries.
