伊朗的核浓缩进展是在外交停滞和国际紧张局势死灰复燃的情况下进行的。 Iran's nuclear enrichment advances amid stalled diplomacy and renewed international tensions.

数十年来,伊朗的核计划一直引起国际关切,其铀浓缩活动导致紧张局势升级,并拒绝充分遵守国际视察。 Iran's nuclear program has been a source of international concern for decades, with tensions escalating over its uranium enrichment activities and refusal to fully comply with international inspections. 美国和盟国已实施制裁,而伊朗则根据《不扩散条约》保留其和平核技术的权利。 The U.S. and allies have imposed sanctions, while Iran has maintained its right to peaceful nuclear technology under the Non-Proliferation Treaty. 关键里程碑包括2015年核协议,该协议限制伊朗的浓缩,以换取制裁救济,以及随后在美国退出协议后于2018年退出协议。 Key milestones include the 2015 nuclear deal, which limited Iran’s enrichment in exchange for sanctions relief, and its subsequent withdrawal in 2018 following the U.S. exit from the agreement. 此后,伊朗增加了浓缩铀的浓缩水平和储存,使人们更加担心拥有核武器的能力。 Since then, Iran has increased enrichment levels and stockpiles of enriched uranium, raising fears of a nuclear weapons capability. 外交努力仍在继续,但在区域持续不稳定和互不信任的情况下,进展依然有限。 Diplomatic efforts have continued, but progress remains limited amid ongoing regional instability and mutual distrust.
