Iranian nuclear chief Ali Akbar Salehi warned that "if European countries delay their cooperation and interaction with Iran, we have many options on the table, though we are not eager to use them". He also indicated that "after [the end of] the nuclear deal, Iran can produce any number of centrifuges as it wishes", adding that "we accepted some restrictions to adhere to our commitments on the JCPOA but these restrictions have not had a significant effect on the speed of Iran nuclear industry development. If it is decided to return to pre-JCPOA era, we will remove uranium enrichment restrictions based on our needs".
