Secretary of Iran�s Supreme National Security Council (SNSC) Ali Shamkhani says the Islamic Republic will under no circumstances enter negotiations beyond the nuclear agreement it clinched with six major world states in 2015.

�Regardless of whether Europe has the will or ability to persuade #USA to lift all sanctions at once & Washington�s return to its commitments, there will be no possibility for Iran entering the talks in the new fields, more than JCPOA, under any circumstances,� he said.

The security chief posted the tweet with the hashtag #activeresistance in his tweet.

Shamkhani�s tweet followed remarks by the US administration�s special envoy for Iran, Rob Malley, who is based in a hotel near the venue of talks in the Austrian capital of Vienna between representatives of Iran and the remaining signatories to the JCPOA.

In an interview with the American National Public Radio, Malley was asked about a �follow-up� agreement in case the JCPOA gets back on track.

�What we would pursue is, first of all, a longer agreement. Even though this one lasts quite some time and some of its provisions last forever, of course, it would be better, as in any arms control agreement, to see whether we could get a follow-on deal that extends the timelines,� he replied.
