The whole point of DMCA is that it's a relatively recent extensions/addition to the copyright law that USA had before, which matched the Berne convention. The non-DMCA parts of copyright are pretty much the same in USA as across the whole world, as they have been harmonized with international treaties. The extra requirements of DMCA (e.g. restrictions on circumventing technical measures of copyright protection), however, are country-specific and not widespread elsewhere.
