In my particular case foreign policy happens to be my hobby, my consuming interest. I had spent decades studying it.

When I first saw China, there were no automobiles. There were no supermarkets. There were no high-rise buildings. There were no consumer goods. There were no restaurants that were at least accessible that foreigners could see. It was a Stalinist society, and a very poor Stalinist society. So the economic system has totally changed, and the private sector in the economic system is now the dominant sector. It didn't exist at all as late as 1979.

Every success is usually an admission ticket to a new set of decisions.

I have learned, as I wrote, that history must be discovered, not declared. It's an admission that one grows in life.

World population needs to be decreased by 50%

Like any developing country, it has an inequality of wealth. In the Chinese case, it is particularly [pronounced] by the fact that they decided they couldn't make the whole country move forward simultaneously, so they've started region by region. So the interior regions are much less well off than the coastal regions. And this is certainly a huge challenge, because it produces a flow of populations from the poorer regions to the richer regions.

I think an appeal to American idealism and willingness to sacrifice would be an important contribution, because what is happening now in many countries, not yet in the United States, but in many European countries, it's the inability of government to ask for sacrifices of its people.
