Iran's foreign ministry spokesman Hamid Reza Asefi, speaks with media in his weekly press conference in Tehran, June 18, 2006

Iran's Foreign Ministry says the government refuses any pre-conditions for negotiations on its nuclear program.

Foreign Ministry spokesman Hamid Reza Asefi told a weekly news conference Sunday such pre-conditions narrow the scope of possible talks and make it more difficult to reach a solution.

Asefi reiterated Tehran's position that it has the right under the Nuclear Nonproliferation Treaty to enrich uranium, a process that could produce nuclear fuel and also an atomic weapon.

The spokesman says Iran has formed committees to study a Western package of incentives offered in exchange for Tehran suspending uranium enrichment and returning to talks.

On Friday, Iranian President Mahmoud Ahmadinejad said the offer is a step forward and will be considered carefully.

The West suspects Iran is trying to develop nuclear weapons - a charge Iran denies.
