In terms of adult game nights (or potlucks, parties, etc.), the standard etiquette is everyone takes a turn playing host (since there is some cost incurred/liabilities playing host).

Would you feel entitled to attending such social gatherings, even if your house rules are so vastly different than everyone else's they dissuade anyone from coming?

Also, anthropomorphizing, China is not my friend. More like arch rival, perhaps even nemesis. Canada can come over whenever.
