Both walls of pagoda one found in China? (5)

I believe the answer is:

panda

'one found in china?' is the definition.
(pandas are native to China)

I cannot understand how the remainder of the clue works.

(Other definitions for panda that I've seen before include "One bearlike" , "See 17" , "(a cuddly-looking bear)" , "One eating bamboo" , "Large black-and-white herbivorous mammal" .)

I've seen this clue in The Guardian.
