In this April 8, 2008, file photo, Chinese navy personnel get ready for U.S. Navy guided missile destroyer USS Lassen to dock at the Shanghai International Passenger Quay in Shanghai, China, for a scheduled port visit. The USS Lassen sailed past one of China's artificial islands in the South China Sea on Tuesday, Oct. 27, 2015, in a challenge to Chinese sovereignty claims that drew an angry protest from Beijing, which said the move damaged US-China relations and regional peace.
