There is a (perhaps less intense?) version of this operating in the Slavic nations. I notice it in Poland. Especially the rule of 3. A host offers you food and drink 3 times, and you are suppose to refuse it a few times, and only if they keep offering should you think that they are serious. Likewise, if you have Poles over for dinner, you might ask "Would you like more wine?" My American friends will say "yes" if they want more wine, but the Poles will say "No". Then you have to insist, "Please have more wine!" and they say "No" again, and this goes for a few rounds before they accept the wine.
