Wordtracker has such a small sample size in the US that it's hard to imagine it would do better in targeting specific countries. That said, I haven't tried it in the countries you mention.
The free Trellian Keyword Discovery Tool doesn't allow you to select country, but their premium tools do offer "many regional and language specific keyword databases." Again, I haven't tried these for countries you mention.

Would you please suggest some useful keywords tools?
