DUBAI: Iran’s Foreign Ministry said the upcoming round of Vienna talks could be the last one, in remarks quoted by Al Arabiya TV on Monday. Western officials warned Tehran on Sunday that negotiations to revive its nuclear deal could not continue indefinitely, after the sides announced a break following the election of a new hardline president in Iran. Negotiations have been ongoing in Vienna since April to work out how Iran and the United States can both return to compliance with the nuclear pact, which Washington abandoned in 2018 under then-President Donald Trump, and Iran subsequently violated. Sunday’s pause in the talks came after Ebrahim Raisi, a hardliner and fierce critic of the West, won Iran’s presidential election on Friday. Two diplomats said they expected a break of around 10 days.
