That's correct. We are not a party to the convention itself, and many countries are not parties to that convention.
Basically, the criteria it lists also form part of international customary law, so we see ourselves as looking at those criteria for the recognition, but obviously it's not as though you meet the juridical or the legal tests and therefore you have a state. There is an eminently sovereign decision by other states, obviously taking into consideration those elements. It's been a well-established practice over time.
