I've been invited to join this debate via an invitation on WT:HK. Categorization of countries without full sovereignty are handled on a per-topic basis. On the topic of bookshops, since Hong Kong has separate ISBN country code, copyright jurisdiction, and business registration regime from China, it would makes sense to categorise this directly into Category:Bookstores by country. See also e.g. Category:National libraries which lists Hong Kong Central Library. Deryck C. 18:33, 21 February 2017 (UTC)[reply]
