The six signatories to the Iran nuclear deal stressed their commitment to the tottering accord during talks held in Vienna on Friday, December 6th, as Tehran vowed to continue to cross the lines on its nuclear programme.
Envoys from Britain, Germany, France, China, Russia, and Iran took part in the three-hour-long meeting.
In what is seen as a breach of the 2015 deal since May, Iran has taken a series of measures, including enhancing uranium enrichment, with another similar move expected in January, AFP reported.
European members have recently begun brandishing the possibility of using the so-called "dispute resolution mechanism" stipulated by the accord, which could cause the resumption of UN sanctions on Iran.
Meeting chair Helga Schmid said participants urged Iran to take "all the necessary steps towards full implementation of its nuclear commitments and to avoid further escalatory steps."
The senior EU official was cited in a statement as saying, "All participants emphasised the key importance of full and effective implementation by all sides, as well as their determination to pursue all efforts to preserve the agreement," France 24 reported.
