San Diego isn’t the only zoo that is expecting new residents. The San Francisco Zoo is also slated to get a panda pair next year, KGO reported.

Giant pandas also will return to the Smithsonian’s National Zoo in Washington D.C. by the end of the year after the zoo’s last pair returned to China in November .

Panda-monium returns: Smithsonian’s National Zoo will have pandas once again

Panda diplomacy started in 1972 when President Richard Nixon worked with the Chinese government during the Cold War to bring pandas to the U.S. The U.S. sent two musk oxen to China in exchange. For decades, pandas lived in the U.S. on loan from China at the cost of up to $500,000 a year per animal, The Washington Post reported.

Last year, China wanted the ones that still lived in D.C., as well as the panda that lived in Memphis, Tennessee, returned.

The only zoo in the U.S. that still had pandas until now was Zoo Atlanta , and its loan agreement expires this year, Forbes reported.
