BRUSSELS - The world powers are committed to hold new round of talks with Iran "as soon as possible," a spokesperson of the European Union (EU) told Xinhua on Wednesday.

A meeting of representatives from UN Security Council's five permanent members -- the United States, Britain, China, France and Russia -- plus Germany, known as P5+1 as well as E3+3, was held here, chaired by the EU foreign policy chief Catherine Ashton.

"E3+3 remain united in their efforts to seek a diplomatic solution to the Iranian nuclear issue," said Ashton's spokesperson, "and necessary contact will be made in the coming days."

The EU is sticking to its dual-track approach, which combines sanctions with political negotiations, towards the resolution of the Iranian nuclear issue.
