Iran will withdraw from the 2015 nuclear deal if there is no economic benefit and major banks continue to shun Iran, Iranian Deputy Foreign Minister Abbas Araqchi said on Thursday. "The deal would not survive this way even if the ultimatum is passed and waivers are extended," Araqchi, Irans lead nuclear negotiator, said in a speech at the Chatham House think tank in London. "If the same policy of confusion and uncertainties about the JCPOA (Joint Comprehensive Plan of Action) continues, if companies and banks are not working with Iran, we cannot remain in a deal that has no benefit for us," Araqchi said, according Reuters. "That’s a fact." Under the deal with Britain, China, France, Germany, Russia and the United States, Iran agreed to restrict its nuclear program in return for the removal of sanctions that have crippled its economy. "If we lose the JCPOA, we will face another nuclear crisis," Araqchi said. "For the Europeans or the world community, when we talk about maintaining the JCPOA and saving it, it’s not a choice between the Iranian or the US market, it’s not a choice for economic cooperation: it’s a choice between having security or insecurity," he said. US President Donald Trump told the Europeans on Jan. 12 they must agree to "fix the terrible flaws of the Iran nuclear deal" or he would re-impose the sanctions Washington lifted as part of that pact. Trump sees three defects in the deal: its failure to address Irans ballistic missile program; the terms under which international inspectors can visit suspect Iranian nuclear sites; and "sunset" clauses under which limits on the Iranian nuclear program start to expire after 10 years. He wants all three strengthened if the United States is to stay in the JCPOA. Meanwhile, a quarterly report by the UN atomic watchdog said Thursday that Iran has stayed within the main restrictions on its nuclear activities imposed by the 2015 deal. Iran did not exceed limits on its stocks of low-enriched uranium and heavy water, the IAEA said.
