The P5+1 group has presented Iran with its corrected prepositions regarding the Islamic Republic's nuclear program, RIA Novosti reported.
Earlier a source in the U.S. delegation said that the country hopes for a solution to the Iranian nuclear problem by diplomatic means.
A EU representative said that Brussels does not expect any breakthrough in the nuclear talks, however it hopes for Tehran to show flexibility at the talks.
Spokesman for EU chief diplomat Catherine Ashton, Michael Mann told RIA Novosti at the briefing before the negotiations that the "six powers" prepared good grounds for the negotiations, and that it all depends on Tehran's reaction to the new presented proposals.
Iranian nuclear negotiating team member Mehdi Mohammadi told RIA that Iran's prepositions to P5+1 group are similar in some ways to those of Russia.
"We have several proposals. First we will listen to what other negotiators say to us, and then will propose our own ideas. They are in ways similar to those which were presented to us by the Russian side, yet they are improved," he said without giving out any details.
Iran's team of nuclear negotiators headed by Secretary of the country's Supreme National Security Council (SNSC) Saeed Jalili arrived in Almaty, Kazakhstan on Feb. 24.
The P5+1 team of negotiators is being headed by the European Union foreign policy chief Catherine Ashton.
Earlier Russia's Deputy Foreign Minister Sergei Ryabkov said that the negotiations between Iran and P5+1 group in Kazahstan will not bring any significant results, however Moscow hopes for Tehran being better prepared for the dialogue with the Six powers.
In 2012, representatives of P5+1 group and Iran held three rounds of talks in Istanbul (April 14), Baghdad (May 23-24) and Moscow (June18-19). None of these meetings resulted in breakthroughs on disputed nuclear issues.
Previously talks between the "Six Powers" and Iran were not conducted for over a year.
The U.S. and its Western allies suspect Iran of developing a nuclear weapon - something that Iran denies. The Islamic Republic has on numerous occasions stated that it does not seek to develop nuclear weapons, using nuclear energy for medical researches instead.
Despite the rules enshrined in the Non-Proliferation Treaty (NPT) entitling every member state, including Iran, to the right of uranium enrichment, Tehran is now under four rounds of UN Security Council sanctions for turning down West's calls to give up its right of uranium enrichment.
