Disclosure

Prosperous Intelligence and The Legation Times are both operated by Cypheon Company Limited. We state it because it changes how you should read this page: This is a related party, not a third party independent of the content we produce. Its data still has to pass the same checks as any other source before it is cited in an article, and the existence of this page shortens those checks at no step at all.
