Big powers say nuclear treaty at risk, cite Iran

GENEVA (Reuters) - The five major nuclear-armed powers said on Friday the Non-Proliferation Treaty was under threat and cited Iran's uranium enrichment campaign in a rare joint call for action to shore up the NPT.

North Korea's nuclear test blast in 2006, Iran's pursuit of potentially bomb-capable enrichment and new allegations Syria covertly tried to build an atomic reactor with North Korean help spotlight growing challenges to the treaty, many analysts say.

"The proliferation of nuclear weapons constitutes a threat to international peace and security," the United States, Russia, China, Britain and France said in a joint address on the final day of a two-week meeting of 106 NPT member nations.

"This ... imperils prospects for progress on other NPT goals such as nuclear disarmament and hurts prospects for expanding international (civil) nuclear cooperation," said British chief delegate John Duncan, speaking on behalf of the five.

"The proliferation risks presented by the Iranian nuclear program continue to be a matter of ongoing serious concern to us." Tehran is under U.N. sanctions for refusing to suspend the work and curbing U.N. inspections meant to verify its nature.

Iran says it wants only electricity from enrichment, which can also produce atom bomb fuel if the process is adjusted.

The five said they stood squarely behind a revised packet of economic incentives which they, along with Germany, plan to present to Iran soon to shelve its uranium enrichment program.

The four Western powers and Russia and China have often struggled to agree on a mix of carrots and sticks for dealing with Iran. But they told NPT members they aimed to resolve the standoff with Iran "innovatively through negotiations".  Continued...
