Who taught Russian in Eastern-bloc satellite countries?

Question

After the USSR gained many satellites countries in central/eastern Europe in 1945, Russian became obligatory at school. It seems those Russian courses were highly unpopular and only a small minority of people managed to actually get fluent in Russian. Did the USSR send actual native Russian teachers to every school to their satellite countries, or did they just force local teachers to teach Russian ? I ask because in my region German language is obligatory at school, but there is a huge lack of German-language schoolteachers and the vast majority of German teachers actually are local teachers, often rather mediocre at the language themselves, but they don't have a choice. The typical result is a awful quality of German course, low motivation for both the teacher and the class, and as a result an overall dislike of German language for schoolchildren, perpetuating the problem to the next generation. I wonder if the situation in soviet satellite countries was analogous.

Answer 1

During the Cold War, Russian was taught mostly by local teachers, i.e. a Polish teacher would teach Russian in Polish schools. Many of the more educated Eastern Europeans, including teachers, became quite proficient in Russian as it would help their careers to be fluent and ties with the USSR were extensive. Up to this day, most of the Eastern Europeans born approx. before 1975 have retained knowledge of Russian.
