伊朗核問題會談開始在哈薩克斯坦舉行大綱

World powers and Iran have begun two days of talks on Tehran's nuclear program.

The discussions opened Friday in Almaty, Kazakhstan among the five permanent members of the U.N. Security Council, plus Germany and Iran.

A spokesman for European Union foreign policy chief Catherine Ashton told reporters Friday that the group hopes Iran will present a response to proposals made to Iran in February. Those proposals include Iran closing a nuclear facility and getting rid of its stockpile of enriched uranium in exchange for permission to trade some products now under international sanctions.

On Thursday, Iran's chief nuclear negotiator, Saeed Jalili, demanded that world powers recognize an Iranian right to enrich uranium.

The United States and its allies accuse Iran of amassing highly-enriched uranium as part of a covert drive to make nuclear bombs. Tehran insists its nuclear program is peaceful.

A senior U.S. official said Wednesday the world powers want Iran to give a "concrete and substantive" response to their proposal.

The U.S. official reiterated that President Barack Obama prefers diplomacy, but is leaving "all options" on the table to deal with the situation.世界諸強國和伊朗開始就德黑蘭的核項目問題展開爲期兩天的會談。

星期五，聯合國安理會五個常任理事國、德國和伊朗開始在哈薩克斯坦的阿拉木圖展開討論。

歐盟外交事務負責人阿什頓的發言人星期五對記者說，世界六強國希望伊朗對2月向德黑蘭提出的建議做出迴應。這些建議包括伊朗關閉一個核設施以及放棄其濃縮鈾儲存，以換取準其出口一些目前依照國際制裁規定不準出口的產品。

星期四，伊朗首席核談判代表賈利利要求世界各強國承認伊朗擁有從事鈾濃縮活動的權利。

美國及其盟國指責伊朗生產高純度鈾以祕密研製核武器。德黑蘭堅持說，伊朗的核項目是爲了和平目的。

一名美國高層官員星期三說，世界各強國要求伊朗對他們有關建議做出“具體和實質性”的迴應。

這名美國官員重申，奧巴馬總統希望通過外交途徑解決問題，但不會排除應對目前局勢的所有選擇方案。
