"Till recently there have always been people on both sides who felt that a strong, stable relationship between the two countries was paramount.

It must be done in a reciprocal, mutually beneficial and constructive way. But this idea of decoupling, of minimizing the amount of contact between the two peoples, is a path toward disaster.

"None of the people who had thought up and fought for and developed the policy of engagement between our two countries ever thought that China was going to become just like the United States."
