Part of Switzerland in China? (6)

I believe the answer is:

canton

This clue is a double definition.

'part of switzerland' is the first definition.
(Swiss administrative subdivision)

'in china?' is the second definition.
('Canton' is part of 'china')

(Other definitions for canton that I've seen before include "It cannot be in Switzerland" , "Swiss state" , "State of Switzerland" , "part of Europe" , "Political district of Switzerland" .)

I've seen this clue in the Evening Standard.
