We are at a very critical stage in these important negotiations. We know that we don't have much time, which is why I am here ... to promote this process, says Grossi at a press conference in Iran's capital Tehran.
Iran announced on Wednesday that the country is not ready to negotiate about the country's enrichment of uranium. The statement came ahead of the next round of talks with the US, which will take place on Saturday.
The first round, between Iran's Foreign Minister Abbas Araghchi and the US's Middle East envoy Steve Witkoff, was held on Saturday. It was the highest level of negotiations between the US and Iran since a previous agreement between Iran and the Western world from 2015 collapsed in 2018. The deal aimed to prevent Iran from developing nuclear weapons after decades of global fear of this.
