"Iran has fully complied with the nuclear deal and there is no place for renegotiating the Joint Comprehensive Plan of Action (JCPOA)," Araqchi said.
"Iran will not withdraw an iota from its legitimate rights," he added.
Araqchi, meantime, said that the Iranian nation did not accept the enemies' excessive demands during the nuclear talks.
Under the 2015 nuclear deal, officially known as JCPOA, Iran was relieved from international sanctions in return for curbs on its nuclear program.
President Trump called for a more restrictive nuclear deal and new constraints on Tehran's missile development and regional clout, issues that are not covered by the JCPOA.
