Germany's Foreign Minister Heiko Mass visited Tehran to meet Iranian President Hassan Rouhani and engage with Foreign Minister Mohammad Javad Zarif as part of the measures taken by the European Union-members to reinstate the groundbreaking JCPOA nuclear agreement and bring an end to the ongoing US-Iran scuffle.
Then, on 20 May, the Atomic Energy Organization of Iran announced that it would quadruple its production of low-enriched uranium and had informed the IAEA, which is tasked with monitoring Iranian compliance with the nuclear deal.
Answering questions from reporters on his way out of the White House on Tuesday, Trump spoke about the trade war with China and the spat over Mexico about immigration, before touching on the tensions between the U.S. and Iran.
"We have said it clearly that economic war is not different from a (military) war at all".
Mr Amano also said he was anxious about the current tensions over the Iranian nuclear issue and called for dialogue.

The European partners had not done enough to provide Iran with alternative ways to trade, he said. The tensions between the U.S. and Iran have increased in the past few months, solid.
There are wars in Syria and Yemen, and it's not a war here, and we do our best to avoid a war. "The Iranian nation has proved during this period that it will resist against pressure and bullying", PressTV cited him as saying.
However, while IAEA chief Yukiya Amano informed reporters about this development, he noted, "I did not say Iran is implementing [the JCPOA], but I did not say Iran is not implementing either".
On Tuesday 18 countries meet in Stockholm to discuss the nuclear dispute between the U.S. and Iran. In withdrawing from the deal, Trump pointed to the accord not limiting Iran's ballistic missile programme, nor addressing what American officials describe as Tehran's malign influence across the wider Mideast. Tehran has responded by threatening to restart uranium enrichment and has called on European nations to salvage what remains of the nuclear agreement.
Last month, Iran scaled back some commitments under the 2015 deal and warned that in 60 days it would resume refining uranium to a higher fissile degree than that permitted by the accord if Europe failed to shield its trade from United States sanctions.
