Tehran - Iran's supreme leader said Wednesday that world powers would not change their policies towards Iran even if Tehran made concessions on its nuclear dispute with them.

Ayatollah Ali Khamenei called the view that Iranian concessions on its nuclear programme would lead world powers to change their policy towards Iran "totally irrational and wrong."

The international community is awaiting Iran's reply to the latest Western-proposed package, under which it is to choose between suspending uranium enrichment and receiving economic incentives in return, or not suspending and facing further financial sanctions.

Concessions in the nuclear dispute would only lead to further demands by the five UN veto powers plus Germany (5+1), state television quoted the Ayatollah as saying. He did not elaborate what those further demands would be.

Under Iran's constitution, Ayatollah Khamenei has the final say on all state affairs. So far, he has shown himself uncompromising in the nuclear dispute.

His remarks on Wednesday indicated Iran would eventually not accept the 5+1 incentive package.

Iranian President Mahmoud Ahmadinejad has also rejected enrichment suspension. But he has vowed to continue talks with the 5+1, including with arch-foe the United States, all beit while rejecting any ultimatum set for them.

Washington said after the July 19 talks in Geneva between Iran and the 5+1 powers that Tehran had two weeks to reply to the offer. That deadline is due to expire Saturday. (dpa)
