VPN it's very hard topic to talk. For example, "quality" of the VPN as a service highly depends from country where you located and VPN company located. Example: I'm in Ukraine, and Ukraine don't have any diplomatic agency with Taiwan, so i can easily use Taiwanese VPN, because ukrainian police or intelligence agency can't force these VPN's to share information about me. I think you understand why so, countries and their services (like police) interact with each other through embassies or consulates. The only way is to use Interpol or some other such services.
On the other hand, it's not a good idea to use taiwanese vpn if you're from USA, because Taiwan is highly dependent of the USA.
Just because two non-hostile countries don't have official diplomatic relations between one another doesn't mean any cooperation can be completely ruled out. Depends on how much of a high-value target one becomes.
Strange reaction, given that user's activity on tor.stackexchange. Maybe he had other reservations about creating new circuits such as extra load to the Tor network?
