Pandas devour ice cake to celebrate 50 years at National Zoo in Washington
- The Smithsonian’s National Zoo and Conservation Biology Institute celebrated 50 years of its iconic panda exchange agreement with the Chinese government
- Chinese ambassador to the US Qin Gang praised the bears as ‘a symbol of the friendship’ between the nations

The “cake” was made from frozen fruit juice, sweet potatoes, carrots and sugar cane and it lasted about 15 minutes once giant panda mama Mei Xiang and her cub Xiao Qi Ji got hold of it.
The most famous tenants at the Smithsonian’s National Zoo and Conservation Biology Institute in Washington had an enthusiastic breakfast on Saturday in front of adoring crowds as the zoo celebrated 50 years of its iconic panda exchange agreement with the Chinese government.
Xiao Qi Ji’s father Tian Tian largely sat out the morning festivities, munching bamboo in a neighbouring enclosure with the sounds of his chomping clearly audible during a statement by Chinese ambassador Qin Gang. The ambassador praised the bears as “a symbol of the friendship” between the nations.

Pandas are almost entirely solitary by nature, and in the wild Tian Tian would probably never even meet his child. He received a similar cake for lunch.
In addition to hailing the 1972 agreement sparked by US President Richard Nixon’s landmark visit to China, Saturday’s celebration also highlighted the success of the global giant panda breeding programme, which has helped bring the animals back from the brink of extinction.
Xiao Qi Ji’s birth in August 2020 was hailed as a near miracle, due to Mei Xiang’s advanced age and the fact that zoo staff performed the artificial insemination procedure under tight restrictions after the Covid-19 pandemic shut the entire zoo. At age 22, Mei Xiang was the oldest giant panda to successfully give birth in the United States.
Normally they would have used a combination of frozen sperm and fresh semen extracted from Tian Tian. But to minimise the number of close-quarters medical procedures, zoo officials used only frozen semen.
