TEHRAN- Iran has promised to keep talking about restoring the 2015 nuclear deal until its "national interests are fully and comprehensively protected," an official media reported. The remarks were made by Ali Bahadori-Jahromi, an Iranian government spokesman, in response to rumours that the US is close to admitting the Vienna nuclear talks failed, as per reports. Iran's primary priority, according to Bahadori-Jahromi, is nuclear discussions. Iran will continue to work within the framework of international diplomatic channels until its economic interests and nuclear rights are protected, according to the official. Iran and world powers signed a nuclear deal in July 2015, formally known as the Joint Comprehensive Plan of Action (JCPOA), in which Tehran commits to limit its nuclear programme in exchange for the lifting of international sanctions. Former US President Donald Trump, however, withdrew the US from the agreement in May 2018 and reimposed unilateral sanctions on Iran, causing the latter to gradually abandon several of the accord's nuclear commitments. Several rounds of talks between Iran and the remaining JCPOA parties have been place in the Austrian capital since April 2021 in order to resurrect the pact. Iran demands guarantees from the US government that it will not quit the deal again and that sanctions will be lifted in a transparent manner.
