A European payment system designed to circumvent US sanctions on Iran will be ready soon, Germany announced on Monday, Al Jazeera reports.
German Foreign Minister Heiko Maas met Iranian President Hassan Rouhani and Zarif in Tehran as part of European efforts to salvage the historic nuclear pact and defuse rising US-Iranian tension.
Iran and Germany held "frank and serious" talks on saving the 2015 nuclear deal with world powers, Zarif told a joint press conference.
"Tehran will cooperate with EU signatories of the deal to save it," Zarif said.
Maas earlier said the payment system, known as Instex, will soon be ready to go after months of work.
