TEHRAN (Dispatches) – President Hassan Rouhani on Saturday said fresh U.S. sanctions imposed on Iran have "further deepened” mistrust that exists between the two countries.

"This is not compatible with the atmosphere of the negotiations,” Rouhani told reporters in Tehran. "It goes against confidence building measures. Mistrust has further deepened.”

The U.S. Treasury on Friday announced dozens of measures targeting Iranian individuals and entities, including shipping and oil companies, banks and airlines.

"Some sanctions like those against drugs or food products are crimes against humanity. We fight and go round these sanctions and we are proud of that,” Rouhani said.

The president said the sanctions are an "oppression of the Iranian nation”. He said: "We should resist the oppression and put the oppressors in their place. We should not allow the continuation and repetition of the oppression.”

However, he pledged that discussions with the P5+1 powers (Britain, China, France, Russia, the U.S. and Germany) would continue.

"We hope to achieve a result within the time limit if the other party acts with goodwill,” he said, noting that three or four difficult questions remain.

Rouhani also said he didn’t know whether he would attend next month’s UN General Assembly and said he had "no plan” to meet U.S. President Barack Obama there. Last year, the two presidents spoke by telephone, the first direct conversation between leaders of the two countries since the 1979 Islamic Revolution.

During his news conference, Rouhani also touched obliquely on the advance of the ISIL in Iraq, saying that Iran had "no plan to cooperate” with the U.S. in the fight against terrorism.

"In our viewpoint, crime is crime,” Rouhani said. "If some say we only fight terrorism if an American is killed, it only indicates they are not serious in fighting.”

Meanwhile, Foreign Ministry spokeswoman Marzieh Afkham said that new U.S. sanctions placed on some Iranian and foreign banks and businesses would have negative consequences on its nuclear negotiations with world powers.

"These actions are inconsistent with the current process of nuclear negotiations,” Foreign Ministry spokeswoman Marzieh Afkham said in remarks quoted by the state news agency IRNA, referring to measure announced by Washington on Friday.

"At a time when the Islamic Republic of Iran has taken confidence building measures based on the agreements, as was reflected by the IAEA reports in Tehran, Iran is expecting the same actions by the U.S. and the rest of the (powers).”

Afkham said the new sanctions would jeopardize the nuclear deal between Iran and world powers.

"These actions have a negative and non-constructive impact on the trend of the talks. The Islamic Republic of Iran rejects any unilateral and self-serving interpretation of last year’s Geneva deal,” she said. "Iran strongly believes that the sanctions are against commitments made by the United States under the Geneva deal.”

Senior Iranian negotiator Majid Takht-Ravanchi described new Iran sanctions as "cruel and unfair”, saying they contradict U.S. claim of goodwill in talks.

"In our view the international sanctions, particularly those imposed by the U.S., are unfair and cruel, and our people will not be affected by such measures,” he said.

"U.S. dual-track policy is not acceptable at all...We consider the leverage (of U.S. sanctions) as not only failed, but also basically ineffective,” he said.

On Friday, Iran’s Foreign Minister Muhammad Javad Zarif said sanctions are an illegal pressure tactic to attempt to influence policy, but they will not affect the people of Iran and Russia.

"If at the beginning of the sanctions Iran had 200 centrifuges, now we have 20,000,” the Iranian foreign minister told the press after a meeting with his Russian counterpart Sergei Lavrov in Moscow.

"They can exert pressure on a country’s people, but nothing more than that. I think, that the people of Russia are ready to take this pressure to protect their lawful rights, as well,” Zarif said.

"This does not mean we want to fight against the world; we are now making all efforts to solve Iran’s problems at the highest level of politics. But it does not mean that sanctions could influence our countries’ people,” Zarif stressed.
