The scene takes place at the China Conservation & Research Centre for the Giant Panda in Sichuan province. Sanjayan told Mashable that the "Chinese have now cracked the code on how to breed [pandas]. And actually how [to] take a captive-born animal and put it back in the wild, which is really the holy grail of re-wilding."
Cracking the breeding code, so to speak, couldn't have come at a better time. The population of endangered pandas, according to the International Union for the Conservation of Nature, numbers in the thousands and continues to fall.
