Good evening. Today, the United States -- together with our close allies and partners -- took an important first step toward a comprehensive solution that addresses our concerns with the Islamic Republic of Iran’s nuclear program. 晚上好。今天，美国与我们的亲密盟友和伙伴一道，朝着全面解决方案迈出了重要的第一步，以处理我们对伊朗伊斯兰共和国核计划的关切。
Since I took office, I’ve made clear my determination to prevent Iran from obtaining a nuclear weapon. As I’ve said many times, my strong preference is to resolve this issue peacefully, and we’ve extended the hand of diplomacy. Yet for many years, Iran has been unwilling to meet its obligations to the international community. So my administration worked with Congress, the United Nations Security Council and countries around the world to impose unprecedented sanctions on the Iranian government. 自我就任以来，我一直明确表示，决心阻止伊朗获得核武器。正如我多次说过的，我强烈希望和平解决这一问题，我们也一直伸出外交之手。然而，多年来伊朗不愿履行对国际社会的义务。因此，我的政府与国会、联合国安理会以及世界各国合作，对伊朗政府实施了前所未有的制裁。
These sanctions have had a substantial impact on the Iranian economy, and with the election of a new Iranian President earlier this year, an opening for diplomacy emerged. I spoke personally with President Rouhani of Iran earlier this fall. Secretary Kerry has met multiple times with Iran’s Foreign Minister. And we have pursued intensive diplomacy -- bilaterally with the Iranians, and together with our P5-plus-1 partners -- the United Kingdom, France, Germany, Russia, and China, as well as the European Union. 这些制裁已对伊朗经济产生重大影响；随着伊朗今年早些时候选出新总统，外交出现了契机。今年秋天早些时候，我亲自与伊朗总统鲁哈尼通话。克里国务卿多次会见伊朗外长。我们还开展了密集外交：既同伊朗人进行双边接触，也与我们的“5+1”伙伴——英国、法国、德国、俄罗斯和中国，以及欧盟——共同推进。
Today, that diplomacy opened up a new path toward a world that is more secure -- a future in which we can verify that Iran’s nuclear program is peaceful and that it cannot build a nuclear weapon. 今天，这场外交打开了一条通往更安全世界的新道路，通往这样一个未来：我们能够核实伊朗核计划是和平的，并且伊朗无法制造核武器。
While today’s announcement is just a first step, it achieves a great deal. For the first time in nearly a decade, we have halted the progress of the Iranian nuclear program, and key parts of the program will be rolled back. Iran has committed to halting certain levels of enrichment and neutralizing part of its stockpiles. 虽然今天宣布的内容只是第一步，但成果十分可观。近十年来，我们首次遏制了伊朗核计划的推进，该计划的关键部分将被回撤。伊朗承诺停止一定程度的浓缩活动，并使部分库存失去作用。
Iran cannot use its next-generation centrifuges, which are used for enriching uranium. Iran cannot install or start up new centrifuges, and its production of centrifuges will be limited. Iran will halt work at its plutonium reactor. And new inspections will provide extensive access to Iran’s nuclear facilities and allow the international community to verify whether Iran is keeping its commitments. 伊朗不得使用新一代离心机进行铀浓缩。伊朗不得安装或启动新的离心机，其离心机生产也将受到限制。伊朗将停止对钚反应堆的工作。新的检查将广泛进入伊朗核设施，使国际社会能够核实伊朗是否履行承诺。
These are substantial limitations which will help prevent Iran from building a nuclear weapon. Simply put, they cut off Iran’s most likely paths to a bomb. Meanwhile, this first step will create time and space over the next six months for more negotiations to fully address our comprehensive concerns about the Iranian program. And because of this agreement, Iran cannot use negotiations as cover to advance its program. 这些都是实质性限制，有助于阻止伊朗制造核武器。简单说，它们切断了伊朗最可能通往核弹的道路。同时，这一步将在未来六个月为进一步谈判创造时间和空间，以全面处理我们对伊朗核计划的关切。由于达成了这项协议，伊朗不能再以谈判为掩护推进其计划。
On our side, the United States and our friends and allies have agreed to provide Iran with modest relief, while continuing to apply our toughest sanctions. We will refrain from imposing new sanctions, and we will allow the Iranian government access to a portion of the revenue that they have been denied through sanctions. But the broader architecture of sanctions will remain in place and we will continue to enforce them vigorously. And if Iran does not fully meet its commitments during this six-month phase, we will turn off the relief and ratchet up the pressure. 美国及我们的朋友和盟友同意在继续实施最严厉制裁的同时，向伊朗提供有限的缓解。我们将不再施加新的制裁，并允许伊朗政府获得一部分此前因制裁而被其拒绝的收入。但制裁的整体架构仍将保留，我们会继续强力执行。如果伊朗在这六个月阶段没有完全履行承诺，我们将取消缓解措施并加大压力。
Over the next six months, we will work to negotiate a comprehensive solution. We approach these negotiations with a basic understanding: Iran, like any nation, should be able to access peaceful nuclear energy. But because of its record of violating its obligations, Iran must accept strict limitations on its nuclear program that make it impossible to develop a nuclear weapon. 未来六个月，我们将努力谈判一项全面解决方案。我们以一个基本共识开展谈判：伊朗和任何国家一样，都应能够获得和平的核能。但由于伊朗过去违反义务，伊朗必须接受对其核计划的严格限制，使其不可能发展核武器。
In these negotiations, nothing will be agreed to unless everything is agreed to. The burden is on Iran to prove to the world that its nuclear program will be exclusively for peaceful purposes. 在这些谈判中，除非一切都达成协议，否则不会就任何事项达成协议。伊朗有责任向世界证明，其核计划将完全用于和平目的。
If Iran seizes this opportunity, the Iranian people will benefit from rejoining the international community, and we can begin to chip away at the mistrust between our two nations. This would provide Iran with a dignified path to forge a new beginning with the wider world based on mutual respect. If, on the other hand, Iran refuses, it will face growing pressure and isolation. 如果伊朗抓住这个机会，伊朗人民将从重新加入国际社会中受益，我们也可以开始消除两国之间的不信任。这将为伊朗提供一条有尊严的道路，以相互尊重为基础，与更广阔的世界开启新的起点。反之，如果伊朗拒绝，它将面临不断加大的压力和孤立。
Over the last few years, Congress has been a key partner in imposing sanctions on the Iranian government, and that bipartisan effort made possible the progress that was achieved today. Going forward, we will continue to work closely with Congress. However, now is not the time to move forward on new sanctions -– because doing so would derail this promising first step, alienate us from our allies and risk unraveling the coalition that enabled our sanctions to be enforced in the first place. 过去几年，国会一直是对伊朗政府实施制裁的重要伙伴，两党共同努力才促成了今天取得的进展。今后，我们将继续与国会密切合作。然而，现在不是推进新制裁的时候，因为这样做会破坏这个充满希望的第一步，使我们与盟友疏远，并有可能瓦解最初促成制裁得以执行的联盟。
That international unity is on display today. The world is united in support of our determination to prevent Iran from developing a nuclear weapon. Iran must know that security and prosperity will never come through the pursuit of nuclear weapons -- it must be reached through fully verifiable agreements that make Iran’s pursuit of nuclear weapons impossible. 今天，全世界都看到了这种国际团结。世界团结支持我们阻止伊朗发展核武器的决心。伊朗必须知道，安全与繁荣永远不会通过追求核武器获得；它们必须通过完全可核查、使伊朗不可能追求核武器的协议来实现。
As we go forward, the resolve of the United States will remain firm, as will our commitments to our friends and allies –- particularly Israel and our Gulf partners, who have good reason to be skeptical about Iran’s intentions. 在我们继续前进时，美国的决心将保持坚定，我们对朋友和盟友的承诺也将保持不变，尤其是对以色列和海湾伙伴；他们有充分理由对伊朗的意图持怀疑态度。
Ultimately, only diplomacy can bring about a durable solution to the challenge posed by Iran’s nuclear program. As President and Commander-in-Chief, I will do what is necessary to prevent Iran from obtaining a nuclear weapon. But I have a profound responsibility to try to resolve our differences peacefully, rather than rush towards conflict. Today, we have a real opportunity to achieve a comprehensive, peaceful settlement, and I believe we must test it. 归根结底，只有外交才能为伊朗核计划带来的挑战带来持久解决方案。作为总统和三军统帅，我将采取必要行动，阻止伊朗获得核武器。但我肩负着深重责任，要努力和平解决我们的分歧，而不是仓促走向冲突。今天，我们有真正机会实现全面、和平的解决，我相信我们必须加以检验。
The first step that we’ve taken today marks the most significant and tangible progress that we’ve made with Iran since I took office. And now we must use the months ahead to pursue a lasting and comprehensive settlement that would resolve an issue that has threatened our security -- and the security of our allies -- for decades. It won’t be easy, and huge challenges remain ahead. But through strong and principled diplomacy, the United States of America will do our part on behalf of a world of greater peace, security, and cooperation among nations. 我们今天迈出的第一步，标志着自我就任以来与伊朗取得的最重大、最切实进展。现在，我们必须利用未来几个月，寻求持久而全面的解决方案，解决这个几十年来威胁我们安全以及盟友安全的问题。这不会容易，前方仍有巨大挑战。但通过坚定而有原则的外交，美国将代表一个更加和平、安全、各国合作的世界，尽到自己的责任。
