Iran's ambassador to the European Union presented Tuesday a new package of proposals aimed at solving the world's "collective challenges", including nuclear energy, a statement said.

Aliasghar Khaji gave the package "on the management of global challenges" to EU foreign policy chief Javier Solana during talks on Tuesday, the embassy statement said.

The proposals contained "the points of view of our country toward the great global difficulties on several political, security, economic and energy levels, and on the question of the peaceful use of nuclear energy," it said.

Earlier, Iranian President Mahmoud Ahmadinejad said that Tehran was ready to talk to world powers about global problems but ruled out negotiations over Tehran's nuclear "rights".

Iran insists it has the right to enrich uranium to make nuclear fuel and has so far defied UN Security Council resolutions which demand a halt to the work, amid fears it has been trying to make an atom bomb.

Highly enriched uranium can also make the fissile core of a bomb but Iran insists its nuclear programme is peaceful and has vehemently denied allegations of seeking to make weapons.

Permanent Security Council members Britain, China, France, Russia and the United States plus Germany have agreed on a "reviewed and updated" offer initially made to Iran in 2006, including economic, security and technological rewards.

Solana, who confirmed Tuesday that a meeting with the ambassador was scheduled, is responsible for talks aimed at getting Iran to accept those incentives.

"I will be meeting with the Iranian ambassador today or tomorrow, to see if we can fix a manner in which we can meet at a higher level," Solana told reporters in Brussels, ahead of the Iranian statement.

His office declined to comment immediately on the statement, which noted that Solana had "promised that he would study (the package) as quickly as possible and that he would keep the Iranian authorities updated on results".

No details of the new Iranian offer have yet been made public, although Russia has said it wants Iran to suspend uranium enrichment during talks on the proposal.

A statement from the embassy on Friday said the package was also aimed at addressing problems in the Middle East, the fight against terrorism and the illicit drug trade.

Khaji has announced a press conference for Wednesday to explain the package in greater detail.
