Iran's top nuclear negotiator Ali Larjani made the remarks to reporters after his meeting with visiting former Iraqi prime minister Ibrahim Jaafari, reported the official IRNA news agency.

"We are talking on the matter now and will decide the accurate place and time of Mr. Solana's meeting with me next week," Larjani was quoted as saying.

However, Solana's spokeswoman Cristina Gallach disclosed earlier Wednesday that the meeting between the two sides would take place next week, without revealing the exact time.

A Western diplomat said on Wednesday that Iran obviously wanted to postpone the meeting to a time after next Thursday's Group Eight (G8) foreign ministerial meeting in Moscow, which may come up with a statement setting a deadline for Iran's compliance on the nuclear dispute.

It was reported that Solana will meet with Larijani on the "ambiguities" which Iran referred to in the six-nation package calling on Iran for a suspension of the uranium enrichment.

On June 6, Solana offered Iran the six-nation incentive package concerning the Iranian nuclear issue, which had been agreed on by the five permanent members of the UN Security Council plus Germany.

Iranian President Mahmoud Ahmadinejad has said his country would formally reply to the six-nation proposals in mid-August.

The United States has accused Iran of secretly developing nuclear weapons under a civilian front, but Iran has repeatedly said its nuclear program is aimed to generate power to meet the country's surging electricity demand.
