Iranian Foreign Ministry spokesman Hassan Qashqavi on Tuesday said Iran intends to continue nuclear talks with the West in a "constructive" atmosphere, the Press TV satellite channel reported.
Both Iran and the West are interested in continuing their negotiations, Qashqavi told a press conference in Tehran.
Qashqavi said a telephone conversation between Iran's top nuclear negotiator Saeed Jalili and EU Foreign Policy Chief Javier Solana was "friendly", adding that their talk was "positive proof" that both sides were willing to pursue talks in a constructive manner.
He said Iran's concerns over the transparency of the West's package should be addressed and hammered out during the meetings with the West.
Qashqavi said Iran insists on its nuclear rights, and the mutual concerns and questions of both sides should be taken into consideration.
On Monday, Jalili and Solana agreed in a telephone conversation to continue nuclear talks on Iran's controversial nuclear program.
Their talks came after six major countries recently agreed to consider new sanctions against Iran in the wake of remarks by Western governments saying Iran failed to give a "clear positive response" to their latest offer of incentives.
Iran's President Mahmoud Ahmadinejad vowed later on Monday that Tehran will never give up its nuclear program despite the risk of fresh sanctions.
The EU issued a decree Friday to consider fresh UN Security Council sanctions against Iran over its controversial nuclear program.
The EU presidency decreed that its financial institutions must exercise restraint on export credits to Iran and that its 27 member states inspect Iran-bound cargoes.
On June 14, Solana handed the offer of incentives to the Iranian authorities on behalf of France, Britain, Russia, China, the United States and Germany during his visit to Tehran in a bid to persuade Iran to halt uranium enrichment.
Iran has also presented its own package of proposals, which is aimed to help resolve regional and international problems, including Iran's nuclear issue.
