Mohammad Javad Zarif and Catherine meeting is a prologue to set the axes of this round of talks.
On the document drafted in the previous round in Vienna, Zarif told reporters that it would not definitely be said that there was a jointly-agreed text. “Agreement would be on only parts of a text; however, in the majority of cases, differences are in content and the manner of drafting the agreement,” Zarif was quoted to say.
This round of talks is reportedly the most complex, technical, and at the same time, longest round, where both sides are resolved to bring the negotiations to a concrete result.
