German Foreign Minister Heiko Maas has called on all sides to show pragmatism and flexibility in talks about the Iranian nuclear deal which are slated to resume later on Saturday afternoon.

Maas told Reuters that “it is about flexibility and pragmatism from all participating parties,” adding “playing for time is in no-one’s interest.”

The talks between world powers and Tehran are aimed at reviving a 2015 nuclear deal that was abandoned 3 years later by then U.S. President Donald Trump, who reimposed sanctions that slashed the country’s oil exports.

Tehran retaliated by breaching the limits imposed under the accord on its nuclear program. It now seeks an end to  sanctions imposed by Washington.

On Thursday, Washington said it had removed sanctions on 3 former Iranian officials and 2 companies that previously traded Iranian petrochemicals, a step one American official called routine but that could show the United States’ readiness to ease sanctions when justified.
