“We have of course adopted some measures in order to prepare the ground for eventually increasing the level of enrichment if it is needed and if the negotiations with the Europeans fail,” he said on Tuesday.
“We are of course continuing to carry out and implement our obligations based on the JCPOA,” he noted in reference to Joint Comprehensive Plan of Action signed between Iran and the P5+1 group of countries in 2015.
Under the JCPOA, Iran undertook to put limits on its nuclear program in exchange for the removal of nuclear-related sanctions imposed against Tehran.
“But at the same time, taking every scenario into consideration, we are preparing ourselves,” he added.
In May, US President Donald Trump announced that he would pull America out of a 2015 nuclear agreement with Iran and re-impose the sanctions that the deal had envisaged to be lifted.
Since the US president pulled Washington out of the nuclear deal, European countries have been scrambling to ensure that Iran gets enough economic benefits to persuade it to stay in the deal. The remaining parties have vowed to stay in the accord.
Earlier in the day, EU foreign policy chief Federica Mogherini announced that European countries have activated a blocking statute that prohibits companies from complying with US sanctions on Iran.
