Iranian President Hassan Rouhani criticized the U.S. new bill to impose sanctions on his country and pledged to take a decisive response.
The House bill would strengthen sanctions on Russian Federation and impose new penalties on Iran and North Korea.
The bill is likely to become law even if Trump decides to veto the legislation, because it has already passed both chambers by veto-proof margins.
In July the United States revealed new economic sanctions against Iran over its ballistic missile programme and said that it was concerned by "Iran's harmful activities across the Middle East".
"Iran will definitely respond to the US hostile move", he noted.
Sanctions against Iran is mainly in response to Tehran's growing missile program.
"As a result, the draft sanctions law is incompatible with different clauses of the JCPOA", he added, using an acronym for the nuclear deal, "under which the U.S. is committed to implementing the deal with good will and in a constructive atmosphere". "The ongoing action in the US Congress... is very clearly a hostile measure against the Islamic republic of Iran", deputy foreign minister Abbas Araghchi said, according to the ISNA news agency.
Araqchi said that the new sanctions are not related to the nuclear sphere, however the act can negatively influence the successful implementation of the July 2015 nuclear deal.
President Trump is pushing for inspections of Iranian military sites as he considers canceling the Obama-era nuclear agreement with Tehran, senior US officials told The Associated Press.
Deputy Chief of Staff of Iran's Armed Forces Brigadier General Massoud Jazayeri said the Trump administration should be cautious more than ever about the United States military approach towards the Islamic Republic.
"During the past six months, the new US administration has certified Iran's commitment to the JCPOA for two times as it had no other choice, because the International Atomic Energy Agency has issued seven reports which clearly confirmed that Iran has abided by the deal", he explained.
What he means by that isn't clear, but State Department spokeswoman Heather Nauert said "Iran's other malign activities are serving to undercut whatever positive contributions to regional and global peace and security were intended to emerge" from the deal. "They don't want to see the deal eroded by American egotism and they don't want to see it jeopardized by a perception in Iran that its benefits have been insignificant".
