== Foo of mainland China categories == 

 It was a consensus recently reached to undelete and to keep category:economy of mainland China. Regarding the term mainland China, please refer to the evidence that I have presented earler at Wikipedia talk:categorisation. The term is not defined purely based on geography. It means the People's Republic of China (PRC) excluding Hong Kong and Macao, as well as territories governed by the Republic of China (ROC), which the PRC claims. You may ask around your friends in Vancouver to testify this. —
