Iran's chief negotiator Said Jalili said that successful talks between Iran and the Group 5+1 (the US, Russia, China, France and Britain plus Germany) are possible only through cooperation.
He further called on the world powers to adopt constructive measures in negotiations with Iran.
In a letter to EU Foreign Policy Chief Catherine Ashton, Jalili, who is also Supreme National Security Council (SNSC) Secretary, warned the G5+1 (the five permanent UN Security Council plus Germany) against adopting unconstructive measures during talks with Iran.
Jalili also said that "Iran is always ready to contribute to initiatives that facilitate successful talks."
He noted that "such talks are only possible in the framework of cooperation, and when they are aimed at winning the trust of the Iranian nation. "
"Those who replace logic with illegitimate measures must be held accountable for any harm to the talks," the top Iranian negotiator stated.
Iran and the Group 5+1 have already held several rounds of talks.
Iran and the six world powers had two days of hectic negotiations in Russia on June 18-19. At the end of the talks, Iran's top negotiator Saeed Jalili and EU foreign policy chief Catherine Ashton announced that they will hold a meeting after talks between their deputies.
Baqeri and deputy head of EU's foreign policy affairs Helga Schmid will meet after an expert meeting in Istanbul on July 3.
After a meeting between Baqeri and Schmid, Jalili and Ashton will meet again.
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.
Tehran has dismissed West's demands as politically tainted and illogical. It always stresses that "sanctions and pressures merely consolidate Iranians' national resolve to continue the path."
Political observers believe that the United States has remained at loggerheads with Iran mainly over the independent and home-grown nature of Tehran's nuclear technology, which gives the Islamic Republic the potential to turn into a world power and a role model for the other third-world countries.
