Chinese tourists visit Beijing's military museum

A Chinese woman poses for a photograph as she straddles the muzzle of an old Chinese tank on display at Beijing's National Military Museum of Revolution March 22, 2009. The head of the U.S. Pacific Command last week stated that China's "aggressive and troublesome" run-in with an unarmed American ship shows that Beijing is not yet ready to behave acceptably.
