MOSCOW (Sputnik) – If the Joint Comprehensive Plan of Action (JCPOA) is renewed, Iran will need a guarantee that sanctions will not return with changes to the US government, Iranian Ambassador to Russia Kazem Jalali said.”We have a poor experience with the Western approach to the JCPOA: the Americans have changed government and they have violated their obligations under the JCPOA. Therefore, the people of Iran have a right to know about future guarantees so that sanctions will not be imposed again,” Jalali said.He went on to say that sanctions were essentially a form of oppression against the Iranian people, which is why such guarantees are necessary.The JCPOA was signed in 2015 by the United Kingdom, Russia, China, Germany, the US, France, the European Union, and Iran, imposing restrictions on the advancement of the Iran nuclear program in exchange for the lifting of US sanctions. In 2018, former US President Donald Trump unilaterally withdrew from the JCPOA and reimposed sanctions on Iran. The Iranian government responded with a gradual retreat from JCPOA obligations.Head of Iranian Delegation Says Progress Made in JCPOA Talks in Vienna30 December 2021, 20:17 GMTSince April 2021, Vienna has been hosting talks to restore the deal.
