'We stress that the continued voluntary and goodwill based actions by the Islamic Republic of Iran are rooted in the principle of reciprocity of rights and duties' in the nuclear deal, the foreign ministry said in a statement
Iran on Monday urged the European parties to the 2015 nuclear deal "to take practical, effective and responsible decisions" to save the landmark agreement.
"We stress that the continued voluntary and goodwill based actions by the Islamic Republic of Iran are rooted in the principle of reciprocity of rights and duties" in the nuclear deal, the foreign ministry said in a statement.
"Any expectation for Iran to return to the conditions prior to May 8, 2019 without proof of any political will and practical ability of the European parties" to ensure sanctions relief "is an unrealistic expectation".
The statement comes a day after three key European powers- Britain, France and Germany- called for an end to the escalating tensions between US and Iran.
As tensions further intensified between the two countries, Britain, France and Germany expressed concern on Sunday that the 2015 deal over Iran's nuclear programme risked further unravelling but said it was up to Tehran to ensure the deal survived.
The statement was published after President Emmanuel Macron hosted German Chancellor Angela Merkel and senior British cabinet minister David Lidington at the annual Bastille Day parade in Paris.
The three European powers were among the key players in the 2015 deal (known as the Joint Comprehensive Plan of Action or JCPOA) on Iran's nuclear programme.
But US President Donald Trump in 2018 announced Washington was pulling out of the deal, to the dismay of its European allies.
