Tehran:Iranian Foreign Minister Mohammad Javad Zarif reiterated that the 2015 nuclear deal or the Joint Comprehensive Plan of Action (JCPOA) is not renegotiable.
In a series of tweets on Thursday, Zarif said: "JCPOA cannot be renegotiated, period.
"If 2021 is not 2015, it's not 1945 either. So let's change UN Charter and remove the veto so often abused by US.

"Let's stop posturing, which we both did 2003-2012 to no avail, and get down to implementing JCPOA which we both actually signed on to."
Zarif's remarks came after Wendy Sherman, US President Joe Biden's nominee for Deputy Secretary of State, called for a new "stronger" deal with Iran.
On Tuesday while speaking to his French counterpart Emmanuel Macron, Iranian President Hassan Rouhani said that the "JCPOA is by no means renegotiable, and the only way to protect and revive it is to remove sanctions by the US".
