Nothing is more international than nationalism, the great “-ism” of the 19th and 20th century, but these nationalisms tend to be mutually exclusive, where ethnic groups and national borders do not coincide.
The establishment of the Alliance of European National Movements (AENM) is an effort to lay the foundations for a European level party (Europarty) and later a political group in the European Parliament, in order to resist the European Union, immigration and globalisation.
According to the new and still very short Wikipedia article, the Alliance of European National Movements has been formed in 2009 by a number of nationalist and far-right parties in the European Union. Founding members are Jobbik (Hungary), Front National (France), Fiamma Tricolore (Italy), National Democrats (Correction 2 November 2009; see below: Nationaldemokraterna, Sweden) and National Front (Belgium). Other organisations of the European new right have announced participation, including groups from Austria, the United Kingdom, Spain and Portugal.
Here are some news items for further study.

Among others, the racist and fascist British National Party (BNP) (Wikipedia) as well as the Freedom Party of Austria (Freiheitliche Partei Österreichs, FPÖ) (Wikipedia) will probably join the European Alliance of Nationalist Movements.
There are some jolly interesting characters out there.
P.S. Update & Correction 2 November 2009 following comment: Sverigedemokraterna and Nationaldemokraterna are different parties, with own articles in Swedish Wikipedia.
