I think culture and education play much bigger roles than anything else, all the sources I find show Germany and France having similar level of corruption (on top of being geographically and economically close) but completely different level of "social trust".
China's pretty corrupt politically but the social trust is quite high, the highest outside of northern europe as far as I can tell
