German Foreign Minister Heiko Maas held talks Monday with his Iranian counterpart Javad Zarif on the future of the 2015 nuclear deal which he described as "extraordinarily important" for Europe.
The two shook hands in front of cameras before their closed-door meeting at the foreign ministry in Tehran, AFP reporters said.
The nuclear deal is "extraordinarily important" for Europe's security, Maas told reporters overnight after arriving in Tehran on the last leg of a regional tour that took him to Iraq, Jordan, and the United Arab Emirates.
But he added: "We do not want Iran to have nuclear weapons."
For his part, Zarif warned the US on Monday that it "cannot expect to stay safe" after launching what he described as an economic war against Tehran.
He offered a series of threats over the ongoing tensions gripping the Persian Gulf. The crisis takes root in President Donald Trump's decision over a year ago to withdraw America from Iran's 2015 nuclear deal with world powers.
The nuclear deal known as the Joint Comprehensive Plan of Action (JCPOA) was struck between Iran and six major powers -- Britain, China, France, Germany, Russia, and the United States.
"Mr. Trump himself has announced that the US has launched an economic war against Iran," Zarif said. "The only solution for reducing tensions in this region is stopping that economic war."
It saw Iran scale down its nuclear program in exchange for sanctions relief.
But last year the US reimposed sanctions on Iran after its unilateral withdrawal from the deal.
Tehran has urged Europe to uphold commitments made under the deal and help Iran circumvent US sanctions.
Iran has also threatened to scale down its nuclear commitments if its interests are not met.
According to Maas, Germany and its European partners "have made the greatest effort to meet (their) commitments".
He acknowledged that the economic benefits Tehran hoped for from the deal were now "more difficult to obtain" but urged Iran to fully respect the agreement.
It is in Iran's "political and strategic interest to maintain this agreement and the dialogue with Europe," he said.
