Under tightening sanctions imposed by the West, Iran is likely to make some concessions in the upcoming nuclear talks, an Iranian expert has said.

After about a more than one-year-long deadlock over talks on Iran's suspected nuclear program, Tehran in mid-February replied to European Union (EU) Foreign Policy Chief Catherine Ashton's October letter over the resumption of nuclear talks.

Ashton later responded to Iran's proposal, saying that five permanent members of UN Security Council plus Germany (G5+1) agreed to restart nuclear talks with Iran.

Recently different sources have been saying a new round of nuclear talks between Iran and G5+1 countries will get started in the near future, although the venue and timing are yet to be announced.

Dr. Sadeq Zibakalam, a professor of political science with Tehran University, told Xinhua in a recent interview that Iran, under increasing sanctions, is serious and genuine about the upcoming nuclear talks, and will likely make some concessions.

"There are many reasons (why Tehran may give concessions). (For one), sanctions are affecting Iran, especially the sanctions over Iran's central bank. Iran has found it difficult to import and export." said Zibakalam.

However, Iran will not completely give in to the U.S. pressures, the Iranian expert argued.

Making concessions "doesn't mean that we must expect Iran to raise its hands and say that it gives in to the United States," Zibakalam said, adding that "Iran is willing to give concessions, provided that G5+1 also gives some concessions in return."

In February, a confidential report of the UN nuclear watchdog said that the Islamic republic had sped up the production of high-grade enriched uranium over the past few months, which raised concerns about the possible weaponization of Iran's nuclear program.
