For it is mutual trust, even more than mutual interest that holds human associations together. Our friends seldom profit us but they make us feel safe. Marriage is a scheme to accomplish exactly that same end. H. L. Mencken
To deem us simply enemies is to lose the true flavor of our relationship. It was more like the two of us entered into a business partnership in order to more efficiently pursue our mutual interest of hating each other. Patrick Rothfuss
Building a good, stable, and productive China-U.S. relationship is in our mutual interest of our two countries and our two peoples, and also contributes to peace and development. Hu Jintao
