Ueno Zoo
Ling Ling was born at the Beijing Zoo in Beijing, China, on September 5, 1985. He was given to Japan and the Ueno Zoo in November 1992 by China in exchange for a panda which had been born in Japan. The 1992 panda exchange, between China and Japan, which is often called Panda diplomacy, took place to commemorate the 20th anniversary of the normalization of bilateral Sino-Japanese relations in 1972. He remained one of the Ueno Zoo's most popular attractions for over 15 years.
