Iranian Foreign Minister Abbas Araghchi says there are good developments during the second round of talks with the U.S., and a path to agreement has started.

"There has been good developments compared to last round," he said. "Two parties will work on potential agreement documents and exchange them. This does not mean that we will reach an agreement soon but the path has started."

Araghchi told reporters that "I can say compared to the last round we've had very serious discussions and there was a constructive atmosphere where we exchanged our point of view."  

"When we reach the stage of drafting a document, naturally the process will slow down," he said.
