Officials accompanying the president told official media Thursday that Ahmadinejad was slated to present his "innovations" in a speech expected to last up to 30 minutes.

No further details on his proposals were given, although officials in Tehran have already indicated it would involve Iran maintaining its sensitive nuclear fuel activities while pledging to comply with UN inspectors.

Iran, which for the past two years has been negotiating over the issue with Britain, France and Germany, is also keen to widen the talks to include more sympathetic countries that include members of the Non-Aligned Movement.

Making his debut appearance on the international stage, Ahmadinejad -- who was initially denied a US visa to attend the UN summit in New York -- did not touch the thorny nuclear issue when he addressed the UN General Assembly on Wednesday and only lashed out at Western "interventionism".

Before Ahmadinejad's speech, French Prime Minister Dominique de Villepin had reiterated EU warnings that Iran's failure to keep its nuclear non-proliferation promises would see it hauled before the UN Security Council.

Iran resumed converting uranium last month in violation of a deal reached with the so-called EU-3. Uranium conversion is a precursor to enrichment, which can produce reactor fuel but also the core of a nuclear weapon.

Tehran insists it only wants to generate electricity, and insists it has a "right" to continue such work as a signatory of the nuclear Non-Proliferation Treaty (NPT).

In his speech on Wednesday, Ahmadinejad took a swipe at UN members which he said considered that their wealth and power gave them "extended rights" over other countries.
