A senior Iranian official suggested Monday that Iran's former government was not committed enough to reaching an agreement with the world powers who are seeking curbs on its nuclear programme.
Iranian nuclear chief Ali Akbar Salehi said Monday that both sides had to approach nuclear talks in good faith to create a "win-win" result.
But he said the chances of progress were improved by the unity among Iran's new political leadership over what it sought in the next round of talks and what it was prepared to give the world powers.
He did not go into detail but Iran wants an end to the economic and political sanctions it faces over fears it is progressing to nuclear weapons ability. Tehran denies wanting such arms, saying its nuclear programme is peaceful.
The world powers want curbs on Iran's uranium enrichment, which can create both energy and the core of nuclear warheads, as well as for Iran to scrap a reactor that will produce plutonium — another pathway to nuclear arms.
Salehi spoke outside of a 159-nation conference of the UN's International Atomic Energy Agency that is expected to touch on fears over Tehran's nuclear aims.
Iranian President Hassan Rouhani is expected to affirm his commitment to trying to ease tensions in comments to the UN General Assembly this week.
Years of nuclear talks have been inconclusive and western negotiators seeking to curb programmes that Tehran could turn from peaceful to military purposes have partially blamed disunity among top Iranian government figures.
Even with the recent installment of Rouhani and his relatively moderate aides, Ayatollah Ali Khamenei remains the top decision maker on the nuclear and other issues as the country's supreme leader.
But Salehi asserted the talks now had a better chance of succeeding because the new political leaders have a "more full-fledged ... desire" than their predecessors to reach agreement with the United States, Russia, China, Britain, France and Germany.
He described the new government as a "like-minded group ... that would facilitate the resolution of this issue if the other side comes with good intentions."
The United States, one of Iran's toughest critics, has welcomed Iran's more moderate tone under Rouhani and has urged Iranian officials to seize the moment in reducing nuclear tensions.
US Energy Secretary Ernest Moniz, who heads his country's delegation to the Vienna conference, said Monday that Salehi's "words have to be followed by concrete actions."
A date and venue for the next round of talks is expected to be announced within the next few weeks.
In Tehran on Monday, state TV quoted Foreign Ministry spokeswoman Marzieh Afkham as warning that "threatening language against Iran" will backfire, adding: "Interaction with Iran will be possible only through respect."
