Ziad, a Saudi businessman, said the Kingdom's leadership was correct to question the 2015 nuclear accord which had eased sanctions in exchange for Tehran limiting its nuclear program to prevent it from being able to make an atomic bomb.
Over the years reports have surfaced that Riyadh has been interested in procuring nuclear weapons.
He also praised President Donald Trump's announcement Tuesday that the USA was quitting the Iran nuclear deal.
Saudi Arabia has backed a number of Islamist groups attempting to topple Assad, and, like Israel, Saudi Arabia was one of the few countries to welcome Trump's decision to exit the Iran nuclear deal, something his European allies urged him not to do.
"We've always said our concern about this agreement in 2015 was that Iran should not take it as carte blanche to go and expand its territorial influence", he said.
The agreement puts limits on Iran's nuclear program in exchange of the lifting of global sanctions.
The renewed sanctions, aimed at the heart of the Iranian economy, will impact the country's energy, financial, and petrochemical sector.
The statement said that in accordance with the goal of a nuclear-free zone in the Middle East, Iran should obtain nuclear weapons.

Middle East analyst James Dorsey said "the core of Iran's defence policy" is its ballistic missile programme - and they will not compromise.
Saudi Arabia has previously responded to missile attacks with airstrikes.
Ironically this appears to be very much the point for proponents of killing the deal as well, as they hope it will lead to a U.S. war against Iran, with America imposing regime change and installing a weaker government.
Yemeni armed forces, supported by popular committees, fired Wednesday night a ballistic missile at the headquarters of Saudi Information and Electronic Warfare in Najran, southern Saudi Arabia.
Chanting "death to America", most members of the Iranian parliament echoed Ayatollah's sentiment.
Saudi Arabia will develop its own nuclear weapons if Iran does, Foreign Minister Adel al-Jubeir told CNN on Wednesday, amid spiralling tensions between the regional rivals.
German Chancellor Angela Merkel, British Prime Minister Theresa May, and French President Emmanuel Macron condemned Donald Trump's decision.
