Interesting observation. Your "wink" doesn't give me much clue about what aspect of French and Korean attitudes you feel are similar. I'm somewhat skeptical of the idea of a "national attitude", but I've observed that many of my French friends are convinced of the superiority of all things French and appear to be not particularly bothered whether outsiders perceive things in the same way. I think this is the attitude that some people refer to as "French arrogance" etc.

OTOH, some Koreans that I have met and done business with have said things within the first moments of our discussion to emphasize the superiority of Korea and Korean culture (in particular the superiority of Korea in relation to Japan). On more than one occasion this need to say that Korea is great has been quite odd in the context of the discussion we were having. On those occasions I got the feeling that the person I was speaking with was suffering from insecurity rather than having a superiority complex.
