“The sanctions have had no impact on our economy because America had already used all the weapons at its disposal and there was nothing new to use against us,” Rouhani said in remarks carried live on national television.
Earlier this week, the administration of US President Donald Trump unleashed a second round of sanctions against Iran. The punitive measures targeted 700 individuals, banks, aircraft, ships and companies tied to Iran’s energy and financial industries.
In May, Trump exited Iran’s 2015 nuclear deal with six powers and Washington reimposed a first round of sanctions on Iran in August which had been lifted under the accord.
“They just issued a long list of banks, their branches ... and airlines and their planes. And this shows that they are merely trying to affect the Iranian nation psychologically,” Rouhani said after a meeting with the heads of the Parliament and the Judiciary.
The Trump administration had earlier vowed to reduce Tehran’s oil revenue to zero, but it went back on its pledge and gave waivers to almost all major customers of the country.
“It has now become clear that America cannot cut Iran’s oil exports to zero,” Rouhani added.
"Either all [countries] in the region export oil or if Iran's oil exports are to stop, others will be in trouble," he said.
Rouhani also said the US seeks to exert pressure on the Iranian people through imposing "inappropriate" sanctions.
He rejected Washington's claim that it is not after putting pressure on the Iranian nation, but rather on the Iranian government and the Islamic establishment.
The claim, Rouhani said, is "totally incorrect and inaccurate, and they (the American officials) have themselves exposed this fact."
He further stressed that the Iranian people were already standing against US sanctions contrary to what Washington expected.
"The Iranian people have demonstrated their resistance and withstanding and it is clear that the one who is thinking about pressure and oppression against the people is the ruling US administration, not the other side," Rouhani said.
"They are the ones who want to negatively affect people's lives and their everyday livelihood through inappropriate and wrong sanctions," he added.
Rouhani also said that the US had targeted the country's banking system as well as its exports of oil and other goods to hit the Islamic Republic's revenues and its import of basic goods.
