Britain's foreign minister Boris Johnson said on Monday he will discuss ways to protect companies doing business with Iran at a meeting with counterparts from France and Germany on Tuesday after U.S. President Donald Trump pulled out of the Iran nuclear deal.
Under the deal signed in Vienna with six world powers - China, France, Russia, the United Kingdom, the US, Germany, and the European Union - Iran scaled back its uranium enrichment programme and promised not to pursue nuclear weapons in exchange for the lifting of economic sanctions.
Zarif said after Moscow he will travel to Brussels to meet with European Union foreign policy chief Federica Mogherini and foreign ministers of Britain, France and Germany.
U.S. President Donald Trump had announced on Tuesday Washington's pullout from the "defective" 2015 Iran nuclear day, adding that he would re-impose the highest level of economic sanctions against Tehran. Russian diplomats did not see reason for rupture.
Trump announced that the USA would exit the deal on Tuesday at a ceremony at the White House, calling his decision an end to "empty threats" in the Middle East. All these nations have expressed interest in keeping the deal intact even without the US.
"Since the signing of the JCPOA [nuclear deal], we have gone from an atmosphere like a gold rush, to one of utter depression", said a Western trade diplomat on condition of anonymity.
Merkel said the United States decision to withdraw from the deal was a serious blow, and that it would be hard to keep the deal alive, given that a "huge economic power has left".
Iran has threatened to restart "industrial scale" uranium enrichment "with no the limits" whether it does not get guarantees that the transaction fractures which may have been established with Europe since the agreement has been signed will likely be maintained. After meeting him, Mogherini will host a consultation of German, French, and British foreign ministers on May 15 to discuss the Iran accord and the USA threat.
But he added: "If the nuclear bargain is always to continue, the passions of those people of Iran must be assured".
Israel and its allies have blamed the Iranian Revolutionary Guards for initiating Thursday's exchange by launching missiles into the occupied Golan Heights.
Moscow - which values close ties with Israel and yet needs continued Iranian military support in Syria - has called for "restraint from all parties" while faced with the prospect of a wider Middle East conflict. Prime Minister Benjamin Netanyahu said "Iran lied" to the world.
