Iranian Deputy Foreign Minister for Political Affairs Abbas Araghchi has warned of a withdrawal from Tehran in case that the process lead to extravagance, waste of time and irrational causes.
Aragchi leads the Islamic Republic mission in these negotiations, the first part of which ended on Tuesday and will continue next week at the expert level.
The latest state of the technical conversations, initial drafts of possible joint texts and how to hold the conversations were discussed during the meeting.
According to the Iranian diplomat, the negotiation process is progressing on the right track, despite some difficulties, among them, the delay so the United States complies with the provisions when the JCPOA was sealed in 2015.
In May 2018, Washington withdrew from the multilateral treaty and reimposed punitive measures against Tehran that were eliminated in the original deal.
A year after that decision ordered by then US President Donald Trump, Iran began to cut its nuclear obligations to the point that it is currently enriching uranium to 60 percent purity, about 15 times the limit agreed in 2015.
