Iran's Ambassador to Brussels Ali Asghar Khaji made the announcement while talking to the nuclear correspondent of Iran's Student News Agency (ISNA), according to IRNA.

The two-page letter will be submitted to Solana within few hours on Monday afternoon, Khaji was quoted as saying.

The letter discloses Iran's stance on the West's behavior towards Iran's nuclear activities, IRNA said.

ISNA noted that the constructive cooperation between Iran, the International Atomic Energy Agency (IAEA) and six major powers of Britain, China, France, Germany, Russia and the United States has been emphasized in the letter.

"The lack of civilization of dialog has led some powers to adopt pressure means instead of logic," the letter said, adding that "Iran's proposal of disarmament and Non-Proliferation is not pleasing for the powers who have been generating such arms for years."

On June 14, Solana handed an offer of incentives to the Iranian authorities on behalf of the six nations during his visit to Tehran in a bid to persuade Iran to halt uranium enrichment.

Iranian Foreign Minister Manouchehr Mottaki said recently that Iran is working with Solana for further talks on the country's nuclear program.

Earlier on Monday, Iranian Foreign Ministry Spokesman Hassan Qashqavi expressed that the country has no reason to stop uranium enrichment as there is no guarantee that the West would meet the country's demand on nuclear fuel.

The remarks came after Ali Asghar Soltanieh, Iran's ambassador to the International Atomic Energy Agency (IAEA), reportedly said last week that Iran would consider stopping sensitive uranium enrichment if guaranteed a supply of nuclear fuel from abroad.

Recently, the UN Security Council unanimously adopted Resolution 1835 to reaffirm its previous resolutions on Iran and demand full compliance from the Islamic Republic.

It called on Iran, which till now has been under three UN sanctions over its disputed nuclear program, "to comply fully and without delay with its obligations" and to meet the requirements of the IAEA Board of Governors, but without new sanctions.
