"Economic terrorism [waged by the US] has no effect on the Iranian nation and it has only made the region more insecure," Zarif said in a meeting with Qatari Emir in the country's capital city of Doha on Monday.
The top Iranian diplomat also reaffirmed the Islamic Republic's policy to expand ties with all its neighbors and hailed Tehran-Doha relations as a "model" of political relations among countries in the region.
The Qatari monarch, for his part, pointed to the close and brotherly relations between Iran and Qatar, underlining the need for bilateral consultations and deliberations concerning regional and international issues as well as a concerted effort to resolve problems in the region.
Sheikh Tamim also expressed Doha's preparedness to maintain peace and stability in the region.
Zarif, who arrived in Qatar on an official trip on Sunday, left Doha on Monday.
Early in last month, Zarif said that Washington is no longer capable of paying the price to keep its status as the most powerful country in international relations, adding that the US economy is not as unrivaled as it was before and consequently incompetent to pay the price for American superiority.
Speaking on the sidelines of the National Day of Industry and Mining, Zarif told reporters that Europe is now after independence from the US in its economy because the US economy is no longer the unchallenged super economy of the world.
“The point that the US economy is not anymore the unrivaled economy in international relations will have dire consequences for the US in the long run,” the Iranian diplomatic chief highlighted.
Touching upon the EU-proposed mechanism for bypassing anti-Iran sanctions of the US, known as the Instrument in Support of Trade Exchanges (INSTEX), Zarif said that the financial vehicle is not on a par with Europeans’ commitments to Tehran, however, it indicates that the closest of the US allies are distancing themselves from Washington.
Late in May, Iranian Parliament Speaker Ali Larijani quoted Iran’s Supreme Leader Ayatollah Seyed Ali Khamenei as saying that US utilitarianism is in decline as it creates 'international anomalies.
He added the creation of the ISIL terrorist group had roots in the US utilitarianism with the aim of destroying the Islamic nations.
Also, in March, Zarif also censured Washington’s foreign policy and interventionist role in the Middle East, asserting, “Its recklessness just displays panic of an empire in decline.”
Early in November, Top Military Aide to the Iranian Supreme Leader Major General Yahya Rahim Safavi asserted that the US' power is fading away and Washington is unable to win control over Iranians’ economy and fate.
