underarm hair removal marketing?

So having recently been to thailand twice and having to work with a small number of chinese women.
i noticed that underarm hair removal is uncommmon. (they were wearing sleveless dresses and tops, so it was quite obvious).

Mind you, the women i work with live are urbanites and live heavily crowded cities like Beijing and Shanghai. Therefore, a few questions here, with little answers.

1. Hasn't Gilette or Shick gotten to the Chinese market? (everyone's rushing to China like a goldmine now)
2. If its cultural differences, is it that difficult for a huge Company like Gilette or Shick to run mass marketing of the desirebility of shaven underarms. I can't imagine it being too difficult (product placement on popular shows/movies should do the trick)

So apparently, it all started with US women in 1915 with a marketing assault as sleeveless dresses became more popular. a good read here http://www.straightdope.com/columns/read/625/who-decided-women-should-shave-their-legs-and-underarms
