Chilean police officers patrol with bicycles donated by China in Santiago, capital of Chile on Aug 8, 2017. A new donation of Chinese bicycles to be used on local police patrols was formalized Tuesday in a ceremony headed by Felipe Alessandri, the mayor of Santiago, and Chinese Ambassador to Chile Li Baorong.
