以下是讲话全文:President Obama’s Closing Remarks at the Nuclear Security Summit He thanks leaders, says world will be more secure after historic gatheringWashington Convention Center, Washington, D.C.April 13, 2010美国总统奥巴马发表核峰会闭幕词华盛顿会议中心华盛顿哥伦比亚特区2010年4月13日THE PRESIDENT: Good afternoon, everybody. We have just concluded an enormously productive day.总统：大家好。

我们刚刚结束了成就斐然的一天。

I said this morning that today would be an opportunity for our nations, both individually and collectively, to make concrete commitments and take tangible steps to secure nuclear materials so they never fall into the hands of terrorists who would surely use them.我在上午说过，今天我们各国面临一个机会，可以分别和共同作出具体承诺和采取明确措施，确保核材料的安全，防止核材料落入那些无疑会利用它们的恐怖主义分子手中。

This evening, I can report that we have seized this opportunity, and because of the steps we’ve taken -- as individual nations and as an international community -- the American people will be safer and the world will be more secure.今晚，我可以这么说，我们成功地把握了这一机遇，作为具体的国家和国际社会，我们已经采取了措施，美国人民将因此更安全，世界将更稳定。

I want to thank all who participated in this historic summit -- 49 leaders from every region of the world. Today’s progress was possible because these leaders came not simply to talk, but to take action; not simply to make vague pledges of future action, but to commit to meaningful steps that they are prepared to implement right now.我谨在此感谢出席这一具有历史意义的峰会的全体代表，来自世界各地区的49位领导人。

今天之所以能取得进展，是因为这些领导人不仅与会发言，而且采取行动；不是含糊地承诺在未来采取行动，而是承诺他们准备立即实施的有意义的步骤。

I also want to thank my colleagues for the candor and cooperative spirit that they brought to the discussions. This was not a day of long speeches or lectures on what other nations must do. We listened to each other, with mutual respect. We recognized that while different countries face different challenges, we have a mutualinterest in securing these dangerous materials.我还要感谢各位同仁在讨论中所表现的坦率与合作精神。

今天并无冗长的讲话，亦无要求别国如何是从的训诫。

我们互相倾听、互相尊重。

我们认识到，虽然不同国家面临不同的挑战，但我们有着共同的利益，即确保这些危险核材料的安全。

So today is a testament to what is possible when nations come together in a spirit of partnership to embrace our shared responsibility and confront a shared challenge. This is how we will solve problems and advance the security of our people in the 21st century. And this is reflected in the communiqué that we have unanimously agreed to today.因此，当许多国家本着合作精神走到一起承担我们共同的职责和应对共同的挑战时，就能大有作为，今天这一点得到了验证。

这将是我们在21世纪解决问题和增进人民安全的途径。

这也体现在今天我们一致通过的公报之中。

First, we agreed on the urgency and seriousness of the threat. Coming into this summit, there were a range of views on this danger. But at our dinner last night, and throughout the day, we developed a shared understanding of the risk.首先，我们就这一威胁的紧迫性和严峻性达成了共识。

在参加本届峰会之际，人们对这一威胁众说纷纭。

然而，经过昨天晚餐席间乃至今天全天的讨论，我们对这一威胁达成了共同的理解。

Today, we are declaring that nuclear terrorism is one of the most challenging threats to international security. We also agreed that the most effective way to prevent terrorists and criminals from acquiring nuclear materials is through strong nuclear security -- protecting nuclear materials and preventing nuclear smuggling.今天，我们宣布核恐怖主义是国际安全所面临的最具挑战性的威胁之一。

我们还一致认为，防止恐怖主义分子和罪犯获得核材料的最有效方法就是加强核安全——保护核材料和防止核贩运。

Second, I am very pleased that all the nations represented here have endorsed the goal that I outlined in Prague one year ago -- to secure all vulnerable nuclear materials around the world in four years' time. This is an ambitious goal, and we are under no illusions that it will be easy. But the urgency of the threat, and the catastrophic consequences of even a single act of nuclear terrorism, demand an effort that is at once bold and pragmatic. And this is a goal that can be achieved.第二，我非常欣慰的是，所有与会国对我一年前在布拉格所阐述的目标予以支持，即在四年时间内确保世界所有易失散核材料的安全。

这是一项宏伟目标，我们非常清楚达到这项目标并非易事。

然而，由于该威胁的紧迫性，还由于哪怕一次核恐怖主义攻击即可导致巨大灾难，我们需要作出既大胆又务实的努力。

这是一个能够实现的目标。

Third, we reaffirmed that it is the fundamental responsibility of nations, consistent with their international obligations, to maintain effective security of the nuclear materials and facilities under our control. Thisincludes strengthening national laws and policies, and fully implementing the commitments we have agreed to.第三，我们重申，根据各国的国际义务，各国承担着基本的责任，必须以有效的方式保障我们控制之下的核材料及核设施的安全。

这包括加强国家法律和政策，全面履行我们一致同意的承诺。

And fourth, we recognized that even as we fulfill our national responsibilities, this threat cannot be addressed by countries working in isolation. So we've committed ourselves to a sustained, effective program of international cooperation on national [sic] security, and we call on other nations to join us.第四，我们认识到，即使在我们履行各自的国家职责时，也需要各国通力合作才能消除这一威胁。
