about the same type of difference is between western europe and slavic people, and even inside the slavic people themselves there is the same gradient - the more eastern ones, like Russians, are more "communal"/less "individualized" than say Polish. And my personal impression is that further east you go, beyond slavic part of Russia, an individuality gets even less respect/recognition, and in particular North Chinese being more individualistic than South, still noticeably less so even than Russians.

A theory that something requires more cooperation in the east vs. west and what applies gradually and across the whole Eurasia continent - what can it be?. I think there must be something else beyond mere cooperation behind the phenomenon of the "a person is nothing" principle getting stronger with move toward the east.
