I see your point (and agree with it), but Hong Kong isn't really the best example here. Hong Kong isn't an independent state, as the protestors there found to their dismay. Not only because it's claimed by China, nor because it's recognized to be part of China by the rest of the world, but because it is in fact part of China, in being as much under the control of Beijing as any other part of the country.
Taiwan, which isn't recognized by most countries, would be a fitting example, though. Again, your actual point stands.
Looking back I think my brain was actually thinking Taiwan and I had a brain fart.
