Foreign Minister Mohammad Javad Zarif has called on the European signatories to the 2015 nuclear deal to back up their pledge of support for the agreement with practical steps.
"European countries should move from showing support in words to support in action and exert pressure for the full implementation of JCPOA," Zarif said, referring to the pact by its official title, the Joint Comprehensive Plan of Action, IRNA reported.
He was speaking to reporters on the sidelines of the International Conference on Security and Sustainable Development in Central Asia hosted by the Uzbek city of Samarkand on Friday, which was attended by high-powered delegations from Asia, Europe and Americas.
"Unfortunately, we are facing bad faith by the United States and a policy of creating an unfavorable environment by its administration. European countries are expected to correct this situation," he said.
Trump's inauguration in January marked a harsh turn in the US policy toward Iran and the deal it brokered with the previous US administration and those of the other five powers to get sanctions relief in return for time-bound curbs on its nuclear development.
He has repeatedly criticized its terms for stopping short of targeting Tehran's missile and regional power, which issues Iranian officials and Washington's European allies agreed to leave out of the pre-deal negotiations.
Trump refused to certify that Tehran was complying with the accord on Oct. 13, giving the US Congress a mid-December deadline to decide whether to reinstate sanctions lifted by the deal.
Zarif said his EU counterpart, Federica Mogherini, assured him of Europe's commitment to the multi-party deal in their meeting on the sidelines of the conference.
"I stressed that the Islamic Republic of Iran has so far implemented its JCPOA commitments," he said.
In his address to the US-sponsored conference earlier in the day, Zarif said, "By clinching the nuclear deal and fulfilling all our commitments under the JCPOA, we have in action proved our compliance with the principles of non-proliferation and nuclear disarmament."
Mogherini also used her speech at the conference to speak up in defense of the agreement.
The nuclear deal was "a major achievement of European and international multilateral diplomacy", she said.
"The European Union will make sure it will continue to be fully implemented by all, in all its parts."
Germany, Britain and France, which helped former US president Barack Obama negotiate the landmark deal with Iran, have criticized Trump's bellicose stance and announced their determination to shore up the deal against his hostile attempts.
While expressing support for Trump's assertion that Iran's missile program and regional influence should be checked, they have dismissed the Republican hawk's demand that negotiations be reopened to amend the deal and impose broader and more restrictive provisions on the Islamic Republic.
They insist that any action on the West's non-nuclear issues with Iran should not interfere with JCPOA's implementation.
