Continuing to maintain and implement the Iran nuclear deal is the responsibility of all parties concerned, and is the common wish of the global community, said Wang, adding that this will help uphold worldwide non-proliferation regime, maintain regional peace and stability as well as solve other hot issues in the world.
On Friday, Trump again waived sanctions against Iran that were lifted as part of the landmark nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA).
"Despite my strong inclination, I have not yet withdrawn the United States from the Iran nuclear deal", Trump said in a statement, saying the options were to fix "the deal's disastrous flaws or the United States will withdraw".
Moscow expects the United States to present two anti-Russian reports with the sanctions, Ryabkov told Tass news agency. "Our worst fears are being confirmed", he said.
The solidity of Iran and worldwide support for the agreement have blocked attempts by Trump and Israel to terminate this agreement or make changes to it, said the statement.
Implementation of the deal hasn't been derailed, but will face some new complicating factors, said the minister.
The 2015 deal, known as the Joint Comprehensive Plan of Action, was signed by the United States under the previous administration of president Barack Obama as well as Iran, China, Russia, Britain, France and Germany.
Britain, France and Germany called on Trump on Thursday to uphold the pact.
Republican Senator Bob Corker said "significant progress" had been made on bipartisan congressional legislation to address "flaws in the agreement without violating USA commitments".
Iran has said it's not interested in any renegotiation and would nearly certainly view a side agreement between the USA and Europe as a violation of the deal.
But Trump, who must meet regular deadlines to endorse the deal every 90 days and approve sanctions waivers every 120 and 180 days, has railed against the agreement.
This would not entail negotiations with Iran but would be the result of talks with European allies, the official said.
Trump laid out conditions to keep Washington in the deal.
A decision to withhold a waiver would have effectively ended the deal that limits Iran's nuclear programme. The other parties to the agreement would have been unlikely to join the United States in reimposing sanctions.
The statement from his ministry further criticised new sanctions on 14 individuals announced by the US Treasury on Friday over human rights issues and Iran's missile programme. The appeal was made after the Iranian Foreign Minister met with European Union foreign ministers and European Union foreign policy chief Federica Mogherini in Brussels on Thursday.
