"Secretary Pompeo's speech has not demonstrated how walking away from the Joint Comprehensive Plan of Action (JCPOA,) has made or will make the region safer from the threat of nuclear proliferation or how it puts us in a better position to influence Iran's conduct in areas outside the scope of JCPOA," said the EU's foreign policy chief Federica Mogherini in a statement released on Monday.
The EU's foreign policy chief went on to call on the US to honor its commitments to the deal.
"This deal belongs to the international community, having been endorsed by the United Nations Security Council. The international community expects all sides to keep the commitments they made more than two years ago," Mogherini added.
She also noted that International Atomic Energy Agency (IAEA) has on multiple occasions confirmed that Iran has implemented "all its nuclear related commitments" under the agreement.
Meanwhile, German Foreign Minister Heiko Maas announced that he will travel to US to meet with Pompeo to discuss Washington's stance on the deal.
"I will actually travel to Washington to have a meeting with Secretary Pompeo, and take advantage of that meeting to talk about this," said Maas in reference to Pompeo's remarks.
US Secretary of State Mike Pompeo said on Monday that Washington will increase the financial pressure on Iran by imposing the "strongest sanctions in history" on the Islamic Republic if Tehran refuses to change the course of its foreign and domestic policy.
Iran has said it would remain in the JCPOA for now, pending negotiations with the other signatories in the coming weeks, before making a final decision on its future role in the agreement.
Tehran wants the Europeans to give it clear-cut guarantees about fulfilling their obligations if it remains in the accord.
