TEHRAN, May 15 (Xinhua) -- Iranian Foreign Minister Mohammad Javad Zarif said Tuesday that he had a "good and constructive" meeting with the EU Foreign Policy Chief Federica Mogherini over the survival of 2015 nuclear deal, Tasnim news agency reported.

"We have started working to reach the guarantees," Zarif said referring to Iran's demand that the remaining parties to Iran's nuclear deal or the Joint Comprehensive Plan of Action (JCPOA) should ensure Tehran's interests will be protected.

"It was a good and constructive meeting," he said, adding that "we are on the right track ... to make sure that the interests of the remaining signatories of the JCPOA, especially Iran, will be guaranteed."

Zarif is in Brussels on the final leg of a diplomatic tour to save the 2015 nuclear deal after the recent U.S. withdrawal from the pact. The tour has already taken him to Beijing and Moscow.

Last week, U.S. President Donald Trump said that the United States would withdraw from the Iran nuclear deal, a landmark agreement signed in 2015.

Trump added that he will not sign the waiver of nuke-related sanctions against Iran.

Accordingly, Iran's President Hassan Rouhani said that Iran would remain in the international nuclear deal in case the country's interests are secured by other parties to the agreement.

"If the remaining five countries in the deal live up to their commitments and guarantee Iran's interests, the agreement will survive," he said on Sunday during a meeting with visiting Sri Lanka President Maithripala Sirisena.
