Hardline Iranian President Ebrahim Raisi said on Friday Tehran "never" pins hope on ongoing talks in Vienna aimed at reviving the country's 2015 nuclear agreement with world powers, EDNews reports citing Al-Awsat news. 

Iran and the United States resumed indirect talks in the Austrian capital on Tuesday after a 10-day break, but envoys gave little away as to whether they were closer to resolving various thorny issues.

"We put our hopes on the east, west, north, south of our country and never have any hope in Vienna and New York," Raisi said in a televised speech commemorating the 43rd anniversary of Iran's revolution.

Raisi, whose election last June led to a five-month hiatus in the talks, said Iran would rely on its domestic economic potential rather than expect support from overseas and from the nuclear talks with world powers.

US President Joe Biden's administration publicly pressured Iran on Wednesday to revive the agreement quickly, saying that it will be impossible to return to the accord if a deal is not struck within weeks.

Russian Foreign Minister Sergei Lavrov said on Thursday there was still a long way to go before the deal could be revived.

Raisi said: "Our foreign policy is balanced. Looking toward the West has made the country's relations unbalanced, we need to look at all countries and capacities in the world, especially our neighbors."

His speech was frequently interrupted by chants of "Death to America" - a trademark slogan of the revolution that toppled the US-backed shah in 1979. The audience also chanted "Death to England" and "Death to Israel."

For the second year in a row, Iranians marked the revolution's anniversary by parading vehicles in the streets rather than marching on foot in line with regulations aimed at limiting COVID-19 contagion.

State television aired live footage of cars and motorcycles moving through the streets of dozens of cities and towns where, before the pandemic, tens of thousands of people would march for the annual event.
