中国有句古言，温故而知新。当然，我们过去30年中也遇到了挫折和挑战，我们的关系并不是没有困难的，没有分歧的。但是我们必须一定是对手这种想法不应该是一成不变的。由于我们两国的合作，美中两国都变得更加繁荣、更加安全。我们基于相互的利益、相互的尊重就能有成就。

There is a Chinese proverb: "Consider the past, and you shall know the future." Surely, we have known setbacks and challenges over the last 30 years. Our relationship has not been without disagreement and difficulty. But the notion that we must be adversaries is not predestined -- not when we consider the past. Indeed, because of our cooperation, both the United States and China are more prosperous and more secure. We have seen what is possible when we build upon our mutual interests, and engage on the basis of mutual respect.

不过，这种接触的成功要取决于我们要彼此了解，要能够进行开诚布公的对话，彼此进行了解。就像当年美国乒乓球运动员所说的，我们作为人有着共同的向往，但是我们两国又不同。

And yet the success of that engagement depends upon understanding -- on sustaining an open dialogue, and learning about one another and from one another. For just as that American table tennis player pointed out -- we share much in common as human beings, but our countries are different in certain ways.

我认为我们两国每个国家都应该勾画出自己要走的路，中国是一个文明古国，它有着博大精深的文化。相对而言，美国是一个年轻的国家，它的文化受到来自许多不同国家移民的影响，而指导我们民主制度文件的影响，我有一个非常简单的向往，代表了一些核心的原则，就是所有的人生来平等，都有着基本的权利，而政府应当反映人们的意志，贸易应该是开放的，信息流通应当是自由的，而法律要保证这个公平。

I believe that each country must chart its own course. China is an ancient nation, with a deeply rooted culture. The United States, by comparison, is a young nation, whose culture is determined by the many different immigrants who have come to our shores, and by the founding documents that guide our democracy. Those documents put forward a simple vision of human affairs, and they enshrine several core principles -- that all men and women are created equal, and possess certain fundamental rights; that government should reflect the will of the people and respond to their wishes; that commerce should be open, information freely accessible; and that laws, and not simply men, should guarantee the administration of justice.

当然，我们的国家历史也不是没有过困难的地方，从很多方面来讲，很多年以来，我们是通过斗争来促进这些原则或者是所有的人民能够享受到，为了缔造一个更完美的联合，我们也打过一个很痛苦的内战，把一部分我们被奴役的人口释放出来，经过一段时间才能使妇女有投票权，劳工有组织权，包括来自各地的移民能够全部不接受。即使他们被解放以后，非洲与美国人也和美国人经过一些分开的、不平等的条件，经过一段时间才争取到全面的平等权利，所有这些是不容易的。但是我们对这些核心原则的信念我们取得的进展，在最黑暗的风暴当中是作为我们的指南针。

Of course, the story of our nation is not without its difficult chapters. In many ways -- over many years -- we have struggled to advance the promise of these principles to all of our people, and to forge a more perfect union. We fought a very painful civil war, and freed a portion of our population from slavery. It took time for women to be extended the right to vote, workers to win the right to organize, and for immigrants from different corners of the globe to be fully embraced. Even after they were freed, African Americans persevered through conditions that were separate and not equal, before winning full and equal rights. None of this was easy. But we made progress because of our belief in those core principles, which have served as our compass through the darkest of storms. That is why Lincoln could stand up in the midst of civil war and declare it a struggle to see whether any nation, conceived in liberty, and "dedicated to the proposition that all men are created equal" could long endure.

这就是为什么美国永远为了全世界各地的核心原则说话，我们不寻求把任何政治体制强制给任何国家，但是我们也不认为我们所支持的这些原则是我们国家所独有的，这些表达自由、宗教崇拜自由、接触信息的机会、政治的参与，我们认为这些是普世的权利，应该是所有人民能够享受到，包括少数民族和宗教的族群，不管是在中国、美国和任何国家，对于普遍权利的尊敬，作为美国对其他国家的开放态度的指导原则，我们对其他文化的尊重，我们对国际法的承诺和对未来的信念的原则。

That is why Dr. Martin Luther King could stand on the steps of the Lincoln Memorial and ask that our nation live out the true meaning of its creed. That's why immigrants from China to Kenya could find a home on our shores; why opportunity is available to all who would work for it; and why someone like me, who less than 50 years ago would have had trouble voting in some parts of America, is now able to serve as its President. And that is why America will always speak out for these core principles around the world. We do not seek to impose any system of government on any other nation, but we also don't believe that the principles that we stand for are unique to our nation. These freedoms of expression and worship -- of access to information and political participation -- we believe are universal rights. They should be available to all people, including ethnic and religious minorities -- whether they are in the United States, China, or any nation. Indeed, it is that respect for universal rights that guides America's openness to other countries; our respect for different cultures; our commitment to international law; and our faith in the future.

所有这些都是你们知道关于美国的一些情况，我们有很多要从中国学习。我们看看这个伟大城市的各地，也看看这个房间，我就相信我们两国有很重要的共同点，也就是对未来的信念，不管是美国还是中国，对现在的成就不能感到自满。

These are all things that you should know about America. I also know that we have much to learn about China. Looking around at this magnificent city -- and looking around this room -- I do believe that our nations hold something important in common, and that is a belief in the future. Neither the United States nor China is content to rest on our achievements.
