"Talks could take place before we give an eventual answer. A number of issues and doubts in the package of proposals need to beclarified," Mottaki told a press conference in Baku, capital of Azerbaijan, during a foreign ministers' meeting of the Organization of the Islamic Conference, the Interfax news agency reported.

"That is why there is a need to start negotiations between Iran and other countries, of course without any preconditions, in order to achieve a rapprochement of the parties," he said.

Iranian officials are studying the package of incentives by the six major powers and will inform European countries of Iran's position as soon as they finish work, he said.

The package, aimed at getting Tehran to halt nuclear enrichment, was backed by the five permanent members of the UN Security Council and Germany and presented to Iran by European Union foreign policy chief Javier Solana.

The offer contains economic and political incentives, including talks with the United States, Western help to build nuclear reactors for Iran, a guaranteed supply of nuclear fuel and permission for Iran to buy aircraft and spare parts if Tehran suspends uranium enrichment.

Mottaki said on Saturday Iran would give a response with complete transparency to the six-nation package.
