各国尝试敲定伊朗和计划协议

Progress is reported in talks over Iran's nuclear program. Many of the gaps over technical issues have been resolved. The P5 + 1 group of countries and Iran have a deadline of the end of the month to reach a framework agreement.
 
European delegates arrived in Lausanne for crucial talks on Iran's nuclear program, joining a US team led by John Kerry. Representatives from China and Russia are expected on Wednesday, in an international effort to reach a deal.
 
There is speculation that the Europeans have flown in to reassure Iran the US Congress will not be allowed to torpedo an international agreement, after the Senate announced it is set to vote on a bill that would remove President Obama's ability to lift sanctions, and, with it, much of Kerry's space to negotiate.
 
Milad Jokar, Iran analyst, said: "This could jeopardize the entire diplomatic diplomacy of the United States because it will decrease the trust when it comes to signing treaties with the United States."
 
A higher-level EU delegation is expected to arrive by the end of the week. It will promise to ensure both the US and Iran fulfill their obligations under any agreement, even if the Senate does pass its controversial law. Analysts say it is important to remember there are six parties to these talks, including Russia, China and Europe, all keen to build relations with Iran.
 
"It's important for the Europeans to come out of these negotiations with not only a victory of their own, but also to ensure the process is in line with the sanctions Europe has passed on Iran over the last few years, and, at the same time, Europe wants to position itself for the future when it comes to its relations with Iran," said Guillaume-Xavier Bender, analyst of German Marshall Fund.
 
Delegates on both sides of these talks say progress has been made, and they are determined to reach an agreement this week. Technical issues may be left for nuclear energy experts to hammer out in the coming months, but hopes are high for a headline announcement by Friday.
