Why do asian killers always tunnel?

Sorry if the title sounds racist, but I'm genuinely curious. My servers are NA west and I play killer more than survivor so I don't often get against killers that live in Asia, but when I do they're very likely to tunnel early on in the game before a gen even gets completed. The usual NA west killers I get against wait to tunnel until 2-3 gens are left so most of the time a killer tunnels super early on I always end up being right that they're Asian.

Is it a cultural difference, difference in how they're taught the game by other players, something else, or a combination of things?

Pref don't answer if you don't have experience on Asian servers or aren't Asian

edit: Post locked so I recommend looking at MaexEnerji's, SettingIntentions', and YuriSuccubus69's replies, not just because they live in Asia or are Asian but because it explains the difference in playstyle a lot imo.
