Eastern Europe? Easy, something that uses 9mm Makarov. AFAIK, it is still widely used as a military and police cartridge, and easy to get ahold of. That being said, I'm not sure how much that has changed in the past few years. Also keep in mind that I'm suggesting a military/police cartridge becuase it is easier to get ahold of on the ground, not because it might be easier to bring into the country.
In the Far East, 9mm Parabellum is pretty much the standard. Heck, the Russians are switching to it if they can every afford to, so it might the global gold standard. Well, silver, any way. <img src="/images/graemlins/smile.gif" alt="" />
But... EVERYONE uses .22LR, I just like something that has a bit more oomph.
