美国副总统万斯（J.D. Vance）周四表示，美国与伊朗的核协议谈判"非常接近"取得突破，但双方仍未完全达成一致，总统特朗普尚未决定是否最终签署协议。

万斯在接受采访时表示，谈判双方已就大部分关键条款达成共识，但在一些核心问题上仍存在分歧。“我们正在取得进展，但还没有到达终点，“他说，“总统将仔细评估最终条款后再做决定。”

谈判核心议题

据消息人士透露，当前谈判的焦点集中在以下几个方面：

• 铀浓缩限制：伊朗铀浓缩活动的规模和监督机制
• 制裁解除：美国对伊朗经济制裁的逐步取消时间表
• 核查机制：国际原子能机构（IAEA）的核查权限和频率
• 地区安全问题：伊朗在中东地区的军事活动

国际反应

伊朗方面此前表示愿意在保障主权的前提下达成协议。欧洲多国也对谈判进展表示关注，认为协议的达成将有利于中东地区的稳定。

市场方面，消息传出后原油价格出现小幅波动，投资者密切关注谈判最终结果对全球能源供应的影响。

后续展望

分析人士指出，即便双方达成协议，在美国国内仍可能面临政治阻力。国会部分议员对协议的监督机制和制裁解除速度表示担忧。

US-Iran Nuclear Deal Nears Completion but Key Differences Remain

US Vice President J.D. Vance stated Thursday that nuclear negotiations between Washington and Tehran are “very close” to a breakthrough, though final agreement has not been reached and President Trump has yet to decide whether to sign.

Vance told reporters that most key terms have been agreed upon, but core differences persist. “We’re making progress, but we’re not there yet,” he said, adding that the president will carefully evaluate final terms before making a decision.

The negotiations center on uranium enrichment limits, sanctions relief timelines, IAEA verification mechanisms, and Iran’s regional military activities. Markets showed modest reaction to the news, with oil prices fluctuating as investors weigh potential impacts on global energy supply.
