The EU legal acts in the area of copyright have what is called "EEA relevance". This means that apart from the (still 28) Member States, they are also binding (although with more flexibilities) to Norway, Iceland, Liechtenstein and Switzerland. Thus this reform sets out the copyright framework for 32 countries in Europe.
On top of it, the EU will include pieces of its IPR legislation in trade and association treaties with third countries. Some of our "best selling exports" have been the criminalisation of DRM circumvention (aka: you may have a legal right to use content but at the same time, you are forbidden to exercise this right because of DRM) as well as term lenghts for copyright protection that exceed the Berne Convention.
