Acording to ashoora reporting from fars news:
“All those familiar with the international laws know that Iran will not do renegotiation on something which has been negotiated before and the resolution 2231 will not change by these remarks,” Khatibzadeh told reporters in a video conference on Monday in reference to German officials’ comments on negotiations on a new nuclear deal.
“The nuclear deal is something related to the past and has been negotiated and it has had its own pros and cons and the points in it have been considered precisely and it has been sealed and any change in its form and content means the end of the nuclear deal,” the spokesman said.
He expressed the hope that Europe would understand its position and capacities, noting that the European countries were the parties that have defied their nuclear deal undertakings.
“We expect them to show heed to the realities and realize that Iran neither negotiates nor compromises on its national security,” Khatibzadeh said.
Asked about the Saudi and Bahraini officials’ demand for partnership in any possible negotiations between the US and Iran, he said, “These countries should know their position and their position is clear in the international relations and regional arrangements and they should know their limits and speak to that extent.”
In relevant remarks last month, Iranian President Hassan Rouhani said that the Iranian nation will continue to resist against the US pressures until forcing Washington to surrender to law.
"The Iranian people, through their heroic resistance to the US’ economic war, have proved that Washington’s policy of maximum pressure is doomed to failure," Rouhani said.
“The next US administration should use the opportunity to make up for the past mistakes against Iran,” he noted.
Also in November, Rouhani lauded his nation for their resistance against the US pressures and sanctions in the past 3 years, expressing the hope that the new administration in the White House would take lesson from the past failures and rejoin the nuclear deal.
“People faced economic terrorism in the past three years and showed competent resistance and patience. Our country’s decision is clear and our nation will continue its patience and resistance until the other side bows to the law and rules,” President Rouhani said, addressing a meeting of the national coronavirus campaign headquarters in Tehran.
“We hope that conditions alter in a way that those who have imposed sanctions will come to realize that they have moved along a wrong path, and that they will not attain their goals at all as they should take a lesson from this 3-year experience for the future US government to bow to the laws and rules and return to all its undertakings and (the Iranian) people would witness and feel the prize of their patience and resistance,” he added.
US President Donald Trump, a stern critic of the historic deal, unilaterally pulled Washington out of the JCPOA in May 2018, and unleashed the “toughest ever” sanctions against the Islamic Republic in defiance of global criticism in an attempt to strangle the Iranian oil trade, but to no avail since its "so-called maximum pressure policy" has failed to push Tehran to the negotiating table.
In response to the US’ unilateral move, Tehran has so far rowed back on its nuclear commitments four times in compliance with Articles 26 and 36 of the JCPOA, but stressed that its retaliatory measures will be reversible as soon as Europe finds practical ways to shield the mutual trade from the US sanctions.
Tehran has particularly been disappointed with failure of the three European signatories to the JCPOA -- Britain, France and Germany -- to protect its business interests under the deal after the United States' withdrawal.
On January 5, Iran took a final step in reducing its commitments, and said it would no longer observe any operational limitations on its nuclear industry, whether concerning the capacity and level of uranium enrichment, the volume of stockpiled uranium or research and development.
