The Vienna talks are continuing on Friday with various meetings being held at the political and expert levels, the IRIB reporter said.
The removal of sanctions and the issue of verification and guarantees that the other parties will abide by their obligations this time and the US will not reimpose the sanctions are among the most important and sensitive issues discussed between the parties in recent weeks.
Diplomats have said that there has been some progress in the talks, but there are still remaining issues such the removal of the sanctions on Iran and its verification needed to be discussed over before Iran return to full abidance by the 2015 nuclear deal, from which the United States withdrew in May 2018 and subsequent indifference of the European parties to make up for Iran's losses.
