Overview

• Sedema formally commemorated the September 10, 1975 arrival of Ying Ying and Pe Pe, which began Mexico’s five‑decade panda story.
• Chapultepec’s program produced eight births, including Tohui in 1981, the first panda to reach adulthood outside China and a national cultural icon.
• Xin Xin, born July 1, 1990, is 35 and in the final stage of life, holding the record for the longest‑lived panda born and cared for outside China.
• City environmental authorities said they are evaluating the viability of continuing the conservation legacy at Chapultepec.
• Any future pandas would require a lease consistent with China’s policy of at least ten years and about US$1 million per pair per year.
