Mogherini made the remarks while addressing a meeting with members of the EU Non-proliferation Consortium, IRNA reported.
“Thanks to the nuclear deal, we now have new channels to engage in a constructive manner as some recent developments in Yemen have shown with Iran to discuss regional issues and to discuss also the security matters,” she said.
“With no nuclear deal any negotiations with Iran would be much more difficult not easier,” she noted.
“As the European Union we want to definitely address Iran ballistic missiles and we want to address the arms proliferation in the region but to do so we need the nuclear deal to be preserved,” she added.
Iran says the country's missile program is solely for defensive purposes and is not up for negotiations.
The EU has been trying to strengthen its economic relations with Iran following the US withdrawal from the 2015 nuclear agreement and reimposition of unilateral sanctions against Tehran.
The European bloc has taken many steps, including updating Blocking Statute which let the Europe-based companies to continue work with Iran as well as intruding a financial channel, special purpose vehicle (SPV) to facilitate trade with Iran.
However, Iran says Europe’s political support for the nuclear deal is “valuable”, but that’s not enough, as it must translate its words into action by taking “operational” steps to salvage the Joint Comprehensive Plan of Action (JCPOA) after the US withdrawal, Press TV reported.
The remarks were made by Iranian Deputy Foreign Minister Abbas Araqchi on Tuesday during his meetings with a number of Finnish officials in Helsinki.
Europe says it is “working twenty-four seven” to launch the SPV payment mechanism.
The mechanism is a totally new experience both for Iran and the EU, and this has resulted in some delay in the process, said former head of the European Parliament’s delegation for relations with Iran Tarja Cronberg during a recent visit to Tehran.
The SPV is expected to help Iran and Europe offset the impact of what Araqchi describes as the “failed” policy of imposing sanctions against another country.
“Iran has lived with sanctions for years, and has even gained considerable achievements under the sanctions. The language of respect must replace the language of sanction and threat,” the Iranian diplomat noted.
The US is undermining not only the JCPOA but also the independence and sovereignty of other countries, he added during his meetings with the Finnish Foreign Ministry’s Permanent State Secretary Matti Anttonen, Undersecretary of State Anne Sipiläinen, and Pertti Salolainen, the vice chairperson of the Finnish Parliament’s Foreign Affairs Committee.
