SUE LAWLEY: I'm going to bring in Rick Brownell, who writes history books for high school children I'm told.
RICK BROWNELL: That's correct.
SUE LAWLEY: So your question?
RICK BROWNELL: Thank you. Professor, you were recently in China. It's a nation clearly on the rise on the world stage. To what extent should the United States be concerned about the rise of China, and what can we do diplomatically and economically to counterbalance them?
JEFFREY SACHS: I think the rise of China is a fundamental part of global history right now. History shows in the twentieth century that leading powers and rising powers don't have an easy time of it, and that's exactly the 1914 story, although the exact trigger of the war remains somewhat obscure. But it was clearly an arms race between a rising Germany and a naval leader, the British Empire, that stood as the fundamental fulcrum around which the alliances that finally triggered World War I were oriented. This could happen again. How China evolves will depend, just like John Kennedy says, on our own attitudes and our own form of behaviour. There is nothing fundamental about a conflictual relationship with China, but there is nothing that guarantees that we won't get trapped in one. It will depend heavily on how we behave ourselves, and our own attitudes.
SUE LAWLEY: Mr Brownell, do you want a quick comment on that?
RICK BROWNELL: Er yeah.
SUE LAWLEY: Do you buy that?
RICK BROWNELL: I tend to think…
SUE LAWLEY: A quick one, a quick one.
RICK BROWNELL: …though that China does a little bit of pushing of its own, like the way it's treated Tibet, its policy regarding Taiwan, most recently the test firing of, shooting down a satellite. I mean these are clearly steps that they're deliberately making to say to the world we're here, and no offence but I think that they, you know, are actually acting in an imperialistic fashion.
SUE LAWLEY: There you go, but you get into your them and us, and we, we can't get into a debate about China specifically now. I'm going to move on, Jeffrey, if you don't mind. What about a comment from here?
