United Nations ? The world powers are prepared to provide Iran with advanced technology and possibly even nuclear research reactors if it agrees to suspend uranium enrichment under a package of incentives revealed in full for the first time Thursday.

The package – put together by the United States, Russia, China, Britain, France and Germany – was given to the Iranians on June 6 and some details were leaked at the time.

But the full proposal showed a broader range of economic, political and energy incentives. They include promoting Tehran’s membership in the World Trade Organization, and the possible lifting of U.S. and European restrictions on the export of civilian aircraft and telecommunications equipment.

Under the incentives, the six powers are prepared to help Iran build state-of-the-art light water nuclear power reactors and to give legally binding guarantees that nuclear fuel will be provided for these civilian reactors meant to produce energy.

This would be done by making Iran a partner in an international facility in Russia where all Iranian uranium could be enriched, and establishing a five-year buffer stock, it said.

The six would authorize the transfer of goods “and the provision of advanced technology to make (Iran’s) power reactors safe against earthquakes.”

The package confirmed that a demand by the U.S., France, Britain and Germany that Iran commit to a prolonged freeze on uranium enrichment was softened to require only suspension during negotiations with Tehran.

“We propose a fresh start in negotiations on a comprehensive agreement with Iran” which would be deposited with the International Atomic Energy Agency and endorsed in a Security Council resolution, the six powers said.
