Talks on Iran end in China with no resolution

SHANGHAI (Reuters) - Talks on whether to offer stronger incentives to Iran to curb its nuclear ambitions ended in the Chinese city of Shanghai on Wednesday without "all problems being resolved", the Chinese delegate said.

The gathering was of the five permanent members of the U.N. Security Council -- the United States, Russia, China, Britain and France -- plus Germany and an EU representative.

"We can say we agreed on the main content of a plan to restart negotiations, but not all the problems have been resolved," Chinese Assistant Foreign Minister He Yafei told reporters.

He said the delegates, a tier below minister level, would report back to their governments and continue discussions among themselves.

Tehran insists it has the right to enrich uranium, which it says is to generate electricity. But the United States, Western European powers and their supporters fear Iran's enrichment could give it the means to make nuclear weapons.
