TEHRAN, Aug. 3 (Xinhua) -- The Iranian Foreign Ministry on Thursday condemned the recent endorsement of new sanctions against the Islamic republic by the U.S. president as "illegitimate."

In a statement, the Foreign Ministry Spokesman, Bahram Qasemi, said that Iran reserves the right to respond to Washington's "hostile" measures against Tehran.

"The U.S. move is illegitimate, illogical and contrary to all the human principles as well as the international laws," Qasemi was quoted as saying by the ministry's website.

Washington's anti-Iran actions is another instance of U.S. enmity with the Iranians, he said, adding that it is also an insult to the world consciousness.

Qasemi noted that other countries, involved in signing the Iran's nuclear deal two years ago, also disapprove the "U.S. unilateral" measures in exerting pressures against Tehran.

"The Islamic Republic of Iran will not remain tight-lipped in the face of the U.S. violation of the nuclear deal, also known as JCPOA, and the Iranian parliament and government will soon announce a series of reciprocal measures," he was quoted as saying.

However, Iran will not fall pray to the U.S. and Israeli plots to ignore and violate JCPOA, he stressed.

The Iranian officials have said that by new round of sanctions against Tehran, the U.S. administration is seeking to provoke Iran to withdraw from the 2015 deal which put an end to the decade-long disputes of Tehran's sensitive nuclear program.

U.S. President Donald Trump on Wednesday signed a sanctions bill on Russia, Iran and the Democratic People's Republic of Korea.

Sanctions against Iran is mainly in response to Tehran's growing missile program.

Tehran has emphasized that its ballistic missile advancement is for deterrent purposes and the country will never negotiate over it.

On Thursday, Qasemi reiterated that "Iran has stood up to the United States' hostile moves and is pressing ahead with its efforts to ensure stability and security, and to fight against terrorism in the region," he noted.

"Iran will, by no means, allow the expansionist and destabilizing policies of others to bear fruit," said Qasemi.
