Iran's parliament gave initial approval on Sunday to a bill to boost spending on Tehran's missile programme and the elite Revolutionary Guards in retaliation for new sanctions imposed by the United States.
The general outlines of the motion were passed with 240 votes in favour and one abstention during an open parliamentary session, Xinhua news agency reported.
The legislation is a reaction to a bill ratified recently in the US Senate allowing Washington to impose non-nuclear sanctions against the Islamic Republic.
The vote came after the United States imposed fresh USA sanctions against Iran in July, targeting its missile programme.
Devising the Sunday motion, the Parliament took great care not to violate the nuclear accord and provide excuses for opposing sides, spokesman for Parliament's Committee on National Security and Foreign Policy Hossein Naqavi Hosseini said.
It mandates the government to allocate an additional Dollars 260 million for the "development of the missile programme" and the same amount to the Revolutionary Guards' foreign operations wing, the Quds Force, state news agency IRNA said.
Tehran says the measures violate a 2015 deal with world powers that eased sanctions in exchange for curbs on its nuclear programme.
Araghchi, also in defense, said the countermeasure bill is "much stronger" than US Congress bill against Iran, since it also extends support to the Islamic Republic's armed forces and all related ministries.
The bill also confronts "adventurist and terrorist" United States activities in the region, urging punishments for USA violators of human rights across the globe.
Abbas Araghchi, a deputy foreign minister and senior nuclear negotiator on hand for the vote, said a moderate President Hassan Rouhani's government would support the bill.
Iranian officials deem the anti-Iran sanctions over its ballistic missile program and alleged "support for terrorism" in violation of the spirit, if not the letter, of the JCPOA.
The measure also assigns Foreign Ministry and several other state bodies with the task of preparing a comprehensive plan to counter U.S. threats against Iran within six months.
