Iranian Foreign Minister Mohammad Javad Zarif reacted to victory of the new US president-elect, Joe Biden, saying the future of Iran’s 2015 nuclear deal depends upon behavior of the new US administration.

The top Iranian diplomat said the fate of the landmark deal, officially known as the Joint Comprehensive Plan of Action (JCPOA), depends on the conducts of the United States and that "Tehran is waiting to see the behavior and actions of the new US administration" with regard to the multinational pact.

Zarif went on to say that, "Individuals are certainly important, but what matters are the behaviors and actions, and the Islamic Republic is waiting to see these actions from the new US administration."

According to media reports, Biden — the US President Donald Trump's democratic rival — won the majority of votes in the 2020 US presidential election on November 3.

Trump has so far refused to concede the victory of Biden in the election, where the Democratic candidate won a total of 290 electoral votes compared to Trump’s 214.

Biden has previously expressed a conditional desire to rejoin the Iran nuclear deal.

Also on Tuesday, Ali Rabiei, the spokesman of Iran's administration, said that he hoped the new leaders of the United States would learn from their previous mistakes and return to the Iran nuclear deal abandoned by Trump.

"Mr. Biden has come to the elections with the claim of restoring the prestige of Americans in the world and thinks the US's reputation has been tarnished and I hope the new leaders of the US have learned lessons from the past four years," Rabiei said.

"I hope the next American administration will stop the continuation of previous mistakes and strives to compensate for them. This is a very clear message and a very simple and basic expectation. Returning to the JCPOA and unconditionally abiding by all of its terms is the only step that can be taken in correcting these policies," he added.

"With regard to Iran, I hope the US has learned that force and pressure have no effects and they have witnessed that not only did Iran not surrender to these measures but it became more resilient in defending the dignity and rights of the Iranian people," the spokesman underlined.

Trump, a hawkish critic of the landmark nuclear deal, unilaterally withdrew Washington from the agreement in May 2018, and unleashed the “toughest ever” sanctions against the Islamic Republic in defiance of global criticism.

The US unleashed the so-called maximum pressure campaign and targeted the Iranian nation with draconian restrictive measures in order to bring it to its knees, but Iran's economy keeps humming and is getting back on its feet.

Following its much-criticized exit, Washington has been attempting to prevent the remaining signatories — the UK, France, China and Russia plus Germany — from abiding by their commitments and thus kill the historic agreement, which is widely viewed as a fruit of international diplomacy.
