A senior Iranian official said Sunday that no hasty decisions should be made in the upcoming nuclear talks with the world's major powers, local satellite Press TV reported.

Mohammad Nahavandian, Chairman of Iran's Chamber of Commerce, Industries and Mines, stressed the importance of gradual confidence building as a process in the course of the talks.

Nahavandian said the UN Security Council's five permanent members -- the United States, Britain, France, Russia and China -- plus Germany (P5+1) should work to bring about the removal of the sanctions on Iran as a "first step" in its next round of negotiations with the Islamic republic.

The parties involved in the negotiations can build confidence in the field of economy because win-win approaches can be developed in this area, he said.

"Instead of beating the drum of sanctions, the two sides can experience areas of common interest and move towards positive confidence-building in economic cooperation," Nahavandian was quoted as saying.

Iran is ready to hold constructive talks as long as there are " fair" conditions and the rights of the Iranian nation are heeded, he added.

The Baghdad meeting should also pave the way for mutual understanding and trust instead of making use of threats, said the Iranian official.

The last round of nuclear talks between Iran and the P5+1 concluded in Turkey's Istanbul in April, with all sides describing the talks as positive and agreeing to meet again in the Iraqi capital on May 23.
