Iran's foreign minister will travel to Moscow on May 14 and meet his Russian counterpart, Russia's RIA news agency said, citing a Russian foreign ministry official. "The situation around the Joint Comprehensive Plan of Action following the unilateral withdrawal of the USA was discussed".
Meanwhile, spokeswoman for the European Union's Foreign Policy Chief, Federica Mogherini also called on all regional actors to show restraint and avoid any escalation. "Together with the rest of the worldwide community, we will preserve this nuclear deal", Reuters quoted Mogherini as saying.

"We can see more interaction between Iran and Europe if we reach a clear decision on the JCPOA in a short period of time", Rouhani noted.

She released a joint statement with French President Emmanuel Macron and British Prime Minister Theresa May urging other parties to remain in the deal.
In an earlier phone conversation with Iranian president Hassan Rouhani, the chancellor joined state representatives from France and the United Kingdom in emphasizing that her country remained committed to the terms of the nuclear accord.
"The U.S. should know that it can not easily renege on its global commitments without paying a cost", he noted.
"Breaching and stamping on an agreement endorsed by a United Nations Security Council resolution will lead to damaging consequences on the world stage", he said.
