<P>During Secretary of Defense Robert Gates's visit to China in January 2011, he stressed the importance of solid military-to-military relations. As a result of this visit, the U.S. Air Force (USAF) and People's Liberation Army Air Force (PLAAF) will hopefully engage each other through military exchanges across a wide range of issues rather than in combat.</P><P>The purpose of this report is to help analysts at different levels (tactical, operational, and strategic) examine and engage the PLAAF using the Ten Pillars as a base. The Ten Pillars include organizational structure, leadership, doctrine, officer corps, enlisted force, education, training, logistics and maintenance, and foreign relations.</P>
