For more than two decades, I worked to strengthen military and diplomatic ties with China, alongside scores of other U.S. and allied officials, all of us sincere in our belief that China could be encouraged to join the principled, inclusive network that has served as the backbone of regional security since the end of World War II - and thus the Asian miracle. It is easy for me to imagine having used my time as Secretary of Defense to solidify those ties and bring China into closer partnership with the United States and the other participants in the network.
