Well, in Serbia you have some major EU banks i.e. Intesa, SocGen, CA, Russian VTB, SberBank, Turkish Halk and Chinese BoC as well as Serbian banks such as AIK mts, Postanska etc.. Majority of banks require (for non-residents) corp. owners ID, corp. registry extract not older than 90 days... I don't see anything special or beneficial to have a bank acc. in Serbia. I think it is easier to open an account in Montenegro (Note: I did not open an account in Montenegro)
