According to a statement, published on the Iranian president's information portal, "any new US sanctions against Iran will violate the UNSC Resolution 2231 as well as international norms".
In response to the US move, Iranian President Hassan Rouhani said the same day that Tehran was not going to withdraw from the JCPOA and that the agreement remained between Iran and the five remaining participants of the deal.
Commenting on the issue, a number of senior officials expressed their regret over the US decision.
French President Emmanuel Macron said on his Twitter account, that France, Germany, and the UK "regretted the US decision to leave the JCPOA", warning that the nuclear non-proliferation regime was at stake.
Russian Foreign Ministry, in its turn, expressed its regret, adding that Moscow was open for further cooperation with other JCPOA parties.
Donald Trump announced on Tuesday, that US was withdrawing from the JCPOA, which is also known as the Iran nuclear deal, causing a major backlash among the European allies of the US. He also promised to re-impose the highest level of economic sanctions against Tehran in response to the development of the nuclear program.
