Merkel defended this Wednesday before the legislators the validity and importance of the so-called Joint Comprehensive Plan of Action (JCPOA) signed in 2015 between Iran and six global powers (China, United States, France, United Kingdom, Russia, and Germany).
Merkel told the German parliament on May 16 that while the pact was "anything but ideal.it's not right to cancel this agreement in this situation now".
Iranian President Hassan Rouhani said Trump expected Tehran to leave the deal after the USA withdrawal, but Tehran had refused to follow that plan by trying to save the deal with its remaining signatories.
She said UK, France, Germany and the European Union as a whole - believe that it was wrong to withdraw from the agreement under such circumstances.
The president of the European Council, Donald Tusk, announced that during the informal summit of the EU on the Balkans that will be held on May 17 in Sofia, Bulgaria, it is expected to agree on a common response of the 28 member states of the regional bloc on the JCPOA against the withdrawal of the United States from the agreement.
Meanwhile, Iranian President Hassan Rohani said on May 16 that Tehran will not flag under US pressure.

Iran has described the sanctions as illegal and has warned that if talks to rescue the accord fail, it would ramp up its nuclear programme to a level more advanced.
"The civil war in Syria and the fight against Islamic terrorism have escalated into a regional conflict of an enormous scale, which can not be resolved without Russia, Turkey, Iran, Saudi Arabia, Jordan, and, I would say, Europe", Merkel said in the Bundestag.
He also said Iran would not surrender to USA pressures. "The Iranian nation will resist the USA plots", Iranian news agencies quoted Rohani as saying.
President Donald Trump announced last week the US would pull out of the 2015 accord, which is created to keep Tehran's nuclear ambitions in check and took over a decade to negotiate.
British, French and German foreign ministers met in Brussels on Tuesday to see how they can save the nuclear deal without the United States, but appeared hard-pressed over how their companies could continue doing business with Iran once Washington begins to reimpose sanctions.
