According to doctors, several months prior to the panda's death, aside from her longevity, the animal had suffered from serious diseases, particularly from contracted liver and kidney failure.
Rescued from a frozen river in the Basi Gorge in the southwest China province of Sichuan Province at the age of four, the panda was moved to Fuzhou, capital of southeast China's Fujian Province, CGTN noted.
Basi the panda who lived in captivity most of her life outlived other pandas by nearly two decades.
However, Basi was confirmed as the world's oldest living captive panda by the Guinness World Records only in August this year.
In 1990, Basi together with Pan Pan, a male, became the mascot of the 11th Asian Games, partaking in the festive events in Beijing.
Shi took good care of Basi for 27 years, especially during the panda's recovery from high blood pressure and cataract surgery.
Basi appears to wave during ceremonies to mark her 35th birthday on November 28, 2015. The park later held a memorial for her, calling her "an angel of friendship both at home and overseas".
Her body will be kept preserved for display in a planed "Basi Museum" at the zoo.
The world's oldest panda, named Basi, has died.
In September 2016, the International Union for Conservation of Nature removed the panda from its list of endangered species and classified it as vulnerable, the stage before extinction.
An estimated 1,864 exist in the wild, where they are threatened chiefly with habitat loss, and around 420 others live in captivity in zoos and reserves, the majority within China.
