For China, renting pandas not only means a lot of rental income, but also means a series of opportunities for staff and relevant leaders to study abroad, which was very enviable in China in the mid-1960s. After seeing the benefits of panda rental, various domestic panda breeding institutions spare no effort to promote their own pandas. On the other hand, due to the warming of Sino-US relations and the panda craze in the United States, American zoos can benefit from tens of millions of dollars in huge tickets in just three or two months. In addition to economic benefits, political factors also have a great influence on panda rental. Some big American cities, including new york, have used government resources to encourage or help their zoos to rent pandas from China for exhibitions. Under the influence of various factors, the panda rental door heats up rapidly once it is opened. During the four years from 1984 to 1988, only Los Angeles, San Francisco, new york, San Diego, Toronto, Seattle, Portland, Atlanta, Cagliari, Memphis, Columbus, Detroit, Winnipeg and Florida have rented pandas from China.

In China, the original panda lease was organized and operated by the China Zoo Association, and the zoos that provided giant pandas became the biggest beneficiaries, which made the Ministry of Forestry, which has management authority over nature reserves and wildlife, very envious. The latter quickly joined the panda leasing, using their giant panda breeding base in China Nature Reserve to transport pandas overseas, and sometimes even catching wild pandas directly for leasing. The management of the whole work in China is very chaotic, because the two systems rent pandas at the same time, and it is difficult to accurately count how many pandas are captured and exported because of the loan transaction. In addition, the artificially raised pandas belong to different institutions, so the information cannot be communicated well and the blood relationship is unknown. All breeding institutions have solitary pandas.
