I know there are many who questioned how the United States perceives China's emergence. But as I have said, in an interconnected world, power does not need to be a zero-sum game and nations need not fear the success of another. Cultivating spheres of cooperation, not competing spheres of influence, will lead to progress in the Asia Pacific.

zero-sum game就是指"零和博弈"，指参与博弈的各方，在严格竞争下，一方的收益必然意味着另一方的损失，博弈各方的收益和损失相加总和永远为"零"，双方不存在合作的可能。与zero-sum game相反的是win-win relationship，双方都获利的"双赢"机制。

As with any nations, America will approach China with a focus on our interests. And it's precisely for this reason that it is important to pursue pragmatic cooperation with China on issues of mutual concern, because no one nation can meet the challenges of the 21st century alone. And the United States and China will both be better off when we are able to meet them together. That's why we welcome China's effort to play a greater role on the world stage, a role in which their growing economy is joined by growing responsibility. China's partnership has proved critical in our effort to jumpstart economic recovery. China has promoted security and stability in Afghanistan and Pakistan. And it is now committed to the global non-proliferation regime and supporting the pursuit of denuclearization of the Korean peninsula.

有这么几个词组是badly off, worse off, well off, better off。其中badly off是‘处境艰难'，well off是‘处境优越'，那么很明显，worse off和better off就是他们的比较级形式。

jumpstart本来的意思是因为汽车无法发动，所以借助其他汽车的蓄电池来帮助车子发动。这里的引申含义是帮助进行某项活动。

So the United States does not seek to contain China, nor does a deeper relationship with China mean a weakening of our bilateral alliances. On the contrary, the rise of a strong and prosperous China can be a source of strength for the community of nations. And so in Beijing and beyond, we will work to deepen our strategic and economic dialogue and improve communication between our militaries.

这个contain在这里的意思是‘control something from spreading'，抑制，阻止

Of course, we will not agree on every issue. And the United States will never waver in speaking up for the fundamental values that we hold dear, and that includes respect for the religion and cultures of all people, because support for human rights and human dignity is ingrained in America. But we can move these discussions forward in a spirit of partnership rather than rancor.
