He said, we should all be aware that US president, Donald Trump, is the real game loser , when it comes to the nuclear accord, the JCPOA.
Boroujerdi added: "The Islamic Republic of Iran has always remained committed to its international pledges and will do the same with regards to the JCPOA".
Boroujerdi said: "If the US violates the JCPOA, if the U.S. walks away from the treaty, in order to re-slap economic sanctions on Iran, there will be no justification for Iran to tolerate such limits. We are patiently waiting for the designated time set by the US and will take action upon their decision."
US President Donald Trump, a long-time critic of the JCPOA, has repeatedly threatened to abrogate the nuclear agreement by not extending sanctions waivers when they expire on May 12, if the European signatories to the deal -- Britain, France and Germany -- do not "fix" its "terrible flaws."
Under the multilateral nuclear agreement, reached under Trump's predecessor Barack Obama, Iran undertook to put limits on its nuclear program in exchange for the removal of nuclear-related sanctions imposed against Tehran.
Boroujerdi said Iran has made contingency plans to deal with any US decisions after the 12 May deadline.
