at least 10% of the population. Besides the use in dealings with officials and in courts the law also allows for bilingual signage and guarantees education in the native language. Czech–German relations On 28 December 1989, Václav Havel, at that time a candidate for president of Czechoslovakia (he was elected one day later), suggested that Czechoslovakia should apologize for the expulsion of ethnic Germans after World War II.

German minority in Romania Numerous Romanian Germans have emigrated to Germany, especially after 1989 and are represented by the Association of Transylvanian Saxons in Germany (). Due to this emigration from Romania, the population of native Germans there has been dwindling constantly over the course of the previous decades (for example, in absolute figures:
