The U.S. President Donald Trump once again had to extend waivers that are mandatory under the deal reached between Iran and world powers, officially called the Joint Comprehensive Plan of Action (JCPOA), the Foreign Ministry said in a statement.
On Thursday Iran sanctions expert Jonathan Schanzer from the Foundation for Defense of Democracies tweeted, "A US official I spoke to today believes Iranian expenditures on foreign adventures, nuclear research and missiles, coupled with losses from graft and corruption, have cost the regime $150b".
Trump said this is the last chance, and in the absence of an agreement, the US would not remain a party to the deal.
But Washington also announced sanctions against 14 entities and people, including the head of Iran's judiciary, Ayatollah Sadeq Larijani.
Russia's deputy foreign minister accused the Trump administration of trying to influence Russian elections on Saturday with new sanctions aimed at punishing the country over meddling in the 2016 U.S. presidential election. JCPOA is not renegotiable: "rather than repeating tired rhetoric, US must bring itself into full compliance -just like Iran".
Under its terms, economic sanctions against Iran were to be lifted in exchange for Tehran halting uranium enrichment.
EU powers yesterday urged US President Donald Trump to endorse a key nuclear agreement with Iran, saying the deal is essential for international security. These are separate to the nuclear deal.
Nephew, a former White House and State Department Iran sanctions expert, said legislation could be drafted that might appear to assuage Trump's concerns, but that getting Iran to agree to allow unfettered international inspections or to no time limits on the nuclear deal's restrictions was impossible. He sent the same signal on Friday.
Washington is expected to impose fresh penalties against Russia as soon as early February for its alleged meddling in the 2016 U.S. presidential vote.
During that four-month period, he wants Congress and America's main European allies to draw up a new deal - without negotiating with Tehran - to replace the 'disastrous flaws' in the current agreement.
"The United States will not stand by while the Iranian regime continues to engage in human rights abuses and injustice", Treasury Secretary Steve Mnuchin said in a statement. This follows previous practice, in which a reluctant president has kept the U.S.in the deal but sought other ways to get tough on Iran.
They were speaking following a meeting with Iran's foreign minister, Javad Zarif. However, the ministry did not specify when the response would come.
Other sanctioned firms included another China-based company, Bochuang Ceramic Corp, and the Iranian firm it sought to supply with a chemical compound used in the transmission of electrical signals.
Trump has argued that his predecessor, President Barack Obama, a Democrat, negotiated a bad deal for the United States in agreeing to the nuclear accord.
Trump, the same day he waived the nuclear sanctions, imposed new sanctions on Iran for its human rights abuses and its military adventurism.
