"Believing that having all five partners on the same page from a high-profile international summit will have an impact on North Korea, Bush's goal is a tough united front reinforcing a demand that North Korea completely give up its pursuit of nuclear weapons and insisting that any talks with Pyong-yang occur only with all the partners present."

I agree, only china can somehow influence NK.
