The 3-year-old landed in the city of Chengdu in Sichuan province on Wednesday after a 16-hour flight in a Boeing 777 emblazoned with a picture of a giant bamboo-eating panda.

Under the deal, all cubs born at the National Zoo must move to China by the time they reach four years old for breeding and research.

As a result of artificial insemination, Bao Bao was born on August 23, 2013, at the National Zoo in Washington D.C. It is time that Bao Bao come back to China.

"I havent stopped crying since they loaded to leave the zoo", wrote Arleen Dawn Curtis on the zoo's Facebook page.

After the foundation of the People's Republic of China in 1949, more giant pandas were shipped overseas.

Zoo keepers carry bamboo that will travel with giant panda Bao Bao as she is heads for her new home in China from the National Zoo in Washington, DC, US, Feb 21, 2017. "You guys must be exhausted".

She will be quarantined there for a month before meeting visitors, said base director Wei Rongping, as officials make efforts to accustom her to her new home.

Bao Bao is the offspring of Mei Xiang and Tian Tian, the National Zoo's second pair of giant pandas, loaned from China in 2000.

A panda cub in China has become an global sensation after refusing to let go of its zoo keeper's leg. The mating pair and the youngest cub remain in Washington.

Admirers have included former first lady Michelle Obama, who sent a message to the giant panda cub on the day she was born.

In fact, most giant pandas around the world are on loan from China, and cubs born overseas have to be sent to the Chinese breeding program to expand the gene pool before they turn four.
