Giant panda Bao Bao, born on Aug 23, 2013 through artificial insemination in the United States, has returned to China. Here are photos showing Bao Bao’s growth history. Under a bilateral agreement between the Smithsonian's National Zoo and China, panda cubs born at the zoo to pandas on loan from China belong to China and should be returned before they reach the age of four, so they can join a breeding program.
